Need blueprints for Glock17. Glock17 blueprints needed

In 1980, it was decided to replace the old Walther P.38 pistol in service with the Austrian army with a new pistol chambered for the same cartridge (9x19 Parabellum). The main contender was the Steyr GB, which at the same time has very serious rivals: the Italian pistol Beretta 92, the German P98 and HK 97, as well as the German-Swiss P220. However, eminent, long-established firms have an unexpected competitor - a small firm Glock GmbH. Already experienced in the production of shooting accessories and cold steel, Gaston Glock, having collected the wishes and opinions of various experts, released his pistol. The design of the new pistol was a combination of various solutions and ideas previously tested in various German and Austrian models, but this combination gave the pistol new qualities. The Glock 17 was created as a fairly powerful, lightweight, maximally safe and easy-to-handle combat pistol with a capacious magazine, always ready to fire. The number 17 in the title denoted the capacity of the store. In 1983, the Glock 17 pistol was adopted by the Austrian army, as well as the police under the symbol P90. By 1985, the gun entered service with the security forces of Sweden and Norway. However, the main demand for the Glock 17 was from law enforcement agencies. Subsequently, the Glock 17 pistol was put into service with the police and security forces in about 60 countries of the world, including the USA, Norway, Sweden, the Netherlands, etc. In 1986, the pistol was introduced from the USA. At this time, the police departments were just abandoning revolvers in favor of self-loading 9mm pistols of equal safety and combat readiness, and the Glock 17 aroused considerable interest. In 1996, about 1,200,000 of these pistols were already sold in the United States, providing Glock with good publicity in the process.

Home hallmark Glock pistol 17 refers to the extensive use of plastic in the design, although it should be noted that many firms and designers have experimented with the use of plastic in the design of weapons. The frame of the gun is completely made of durable plastic and can withstand temperatures up to 200°C. The guide frames are additionally reinforced with steel inserts. The total proportion of plastic in the pistol is about 40% of the entire structure, which in turn gave rise to a legend regarding the “invisibility” of Glock pistols for metal detectors. In reality, the mass of metal parts of the pistol is quite enough to trigger any metal detector. Plastic frames, contrary to many rumors, also do not provide "recoil damping", in fact, they provide comfortable contact between the shooter's palm and the handle, making the recoil perceived by the shooter "softer". Their main advantage is a reduction in the mass of weapons, corrosion resistance and cost reduction (high-strength plastic costs less than high-quality steel, and, unlike steel parts, plastic ones do not require additional processing). The casing-shutter of the pistol has a rectangular shape, a flat upper surface and does not have a muzzle sleeve. The impact mechanism, assembled in the shutter, is covered behind with a plastic cover. In general, the gun turned out to be quite easy to use, extremely reliable and unpretentious, as well as relatively light and inexpensive. He is rightfully considered one of the best representatives of his class.

The automatics of the Glock 17 pistol work due to the recoil of the barrel during its short stroke. The barrel bore is locked according to a scheme that is a modification of the Browning High-Power pistol scheme - lowering with the help of lower inclined protrusions of the breech breech. The engagement of the bolt with the barrel has been changed: the rectangular breech of the barrel engages with a groove located on the back of the window for ejection of spent cartridges. This decision simplified the production of casings-gates. The barrel is equipped with a polygonal cut with significantly rounded edges. Such cutting is less prone to abrasion, reduces the risk of the bullet breaking off the rifling and does not damage its shell. The barrel is set quite low, which improves the shooter's control of recoil, increasing the accuracy of fire. USM - shock type. The firing pin is always half-cocked before firing. Glock 17 is not equipped with a non-automatic fuse, but it has 3 automatic ones at once. The first is presented in the form of a lever on the trigger. When this lever is depressed, it, resting against the frame, blocks the trigger. Pressing the trigger (primary) first releases the fuse, then (a stroke of about 5 mm) the striker fuse is raised by the protrusion of the trigger rod, after which the drummer is cocked with a sear located at the end of the rod. The pull also turns off the locking lever (uncoupler), which disconnects the drummer from the trigger rod before the trigger is pressed. The subsequent movement of the (secondary) trigger removes the sear from the groove of the frame, interacts with the uncoupler and lowers, after which the firing pin is released and the primer is subsequently pricked. Speaking of the successful application of old solutions - a “half-cocked” striker was found in the 1907 Roth-Steyr pistol of the year, and an automatic safety located on the trigger was in the 1930 Sauer of the year. Such a trigger scheme provides sufficient safety, since a pistol can be fired only when the bolt is locked in conjunction with the correct trigger pull. The trigger pull of the Glock 17 is 2-4 kgf and is set at the factory. After a shot, the pistol is always automatically set to the safety, which is removed the next time the trigger is pressed.
The Glock 17 handle is made integral with the frame, which provides it with a convenient shape and size with a sufficiently capacious magazine. The magazine is double-row, the cartridges are staggered, in the neck of the magazine the cartridges are rearranged in one row. The angle of inclination of the handle to the axis of the barrel is 112°. The shape of the trigger guard in front is made with the expectation of imposing the index finger of the second hand when firing from two hands. The front and rear grips, as well as the front trigger guard, are knurled to give the pistol greater stability when fired. At the point where the handle converges with the trigger guard, there is a magazine latch that is pressed forward. After all the cartridges are used up, the magazine feeder turns on the shutter delay. The shutter release button is located on the left side of the frame above the grip. To the left above the trigger guard in the recess is the slide of the barrel lock. The surfaces of the gun, made of metal, are treated with a protective matte finish"Tenifer". In addition to the laconic design and low weight, the Glock 17 is distinguished by its overall simplicity: the design consists of only 33 parts, including the store. It can be completely dismantled with a nail or stud in just a minute or less. On the underside of the frame there is a mount that allows you to attach various accessories to the pistol (tactical lights, laser pointer, etc.). Sights in the form of a front sight and a replaceable permanent rear sight are mounted on the casing-gate. They can be equipped with luminous inserts that simplify the process of aiming in low light conditions. The rear sight can be replaced with an adjustable one. Adjustable rear sights are equipped with a sports pistol model with an elongated (153mm) barrel Glock 17L, which is also used by some police special forces in the United States. In addition, there is a Glock 17C variant with a compensator integrated into the barrel, which has the form of a group of slots in front of the upper part of the trunk, which correspond to longitudinal slots located on the upper side of the bolt near the rear sight. The commercial success of the Glock 17 pistol was an impetus for the company, prompting it to create a number of modifications based on it.

In 1980, due to the moral and physical obsolescence of the pistols in service in Austria, a competition was announced for a new army pistol called the Pistole 80. Pistols from such experienced manufacturers as Beretta, Heckler-Koch, Steyr took part in the competition, but in 1982 the Austrian The army officially adopted the pistol of the hitherto practically unknown company Glock model 17 under the designation P80. Prior to the start of the competition, Glock was known mainly as a manufacturer army knives and sapper shovels. Its ambitious owner, Gaston Glock, recruited a team of experienced gunsmiths specifically to participate in the competition and gave them the opportunity to create a pistol “from scratch”, and they succeeded. Using a few unorthodox, but in principle not new ideas, the Glock team managed to create an exceptionally simple, reliable and inexpensive pistol to manufacture.
Based on the already existing positive experience in the use of polymers in the creation small arms in pistols (VP-70 of the German company Heckler-Koch) and assault rifles(AUG of the Austrian company Steyr) Glock engineers created a pistol with a polymer frame. This decision made it possible to reduce the cost of production, increase survivability and corrosion resistance, and lighten the weapon. To ensure the most simple handling of weapons, the Austrians abandoned manual fuses, leaving only automatic fuses. The striker-type trigger with pre-cocked striker was inherited from the Austrian Roth-Steyr pistol of the 1907 model, the automatic trigger safety from the German Sauer pistol of 1930, the modified Browning barrel locking system from the SIG-Sauer P220 pistol. Total number parts of the new pistol, including the store, amounted to only 33.

For more than 30 years since the appearance of the first model 17 Glock pistol, the company has created several dozen models on its basis in all the most popular pistol calibers (9x17, 9x19, .357SIG, .40SW, .45ACP) and even tried to create its own cartridge. 45GAP (Glock Auto Pistol), which turned out to be not so successful. Glock pistols have gained worldwide popularity as army weapon(they are in service not only in Austria, but also in the UK, Sweden and many other countries). In addition, these pistols are popular as police weapon(in particular, in the USA), as well as a civilian weapon for self-defense and sports.

Over the years of the release of Glock pistols, they have changed four generations of models.

The first generation of Glock pistols consisted of the Glock 17 / P80 pistol itself, which had smooth handles with fine corrugation “in a circle”.

The second generation of Glock pistols, which appeared in 1988, additionally included the first compact Glock 19 model and was distinguished by the presence of larger notches on the front and back of the handle.

The third generation of Glock pistols, which appeared in 1998, received a guide for attaching a lantern or laser sight under the barrel, notches for fingers and a “shelf” for thumb on the handle of the weapon and a new ejector, which additionally serves as an indicator of the presence of a cartridge in the chamber.

Fourth generation of Glock pistols, launched in 2010 and produced in parallel with the 3rd generation models, received pistol grips of a reduced cross-section with interchangeable pads on the back of the handle, allowing the weapon to be adapted to shooters with a wide variety of palm sizes. In addition, the 4th generation pistols received an enlarged magazine ejection button, which can be rearranged on both sides of the weapon, and a number of smaller design improvements.

Standing apart from this entire line of weapons is the Glock 18 automatic pistol. Designed for law enforcement, this pistol was never commercially available and was produced in small numbers.

As mentioned above, the main advantages of Glock pistols are ease of construction and use, high reliability, significant resource, relatively light weight. The disadvantages of these pistols are usually not the most convenient shape of the handle (corrected in the current 4th generation of pistols), as well as the absence of any manual safety catches, which, with insufficient user training, periodically leads to accidental shots.
Widely exaggerated in the media mass media The “plastic” design of the Glock pistol, which allegedly led to the fact that the pistol was invisible in x-rays and not detected by metal detectors, is nothing more than a fabrication of the press. In fact, any Glock pistol consists of metal for more than half of its mass and is perfectly detected by any special means.

The automation of all pistols of the Glock series (except pistols of models 25 and 28 in 9x17 caliber) is based on the Browning scheme with a short stroke of the barrel and a rigid locking of one protrusion in the breech breech behind the window for ejecting cartridges in the bolt. The skew of the breech for its unlocking and locking is carried out by the interaction of the figured tide under the barrel with a steel insert in a polymer frame. The gates are made of steel by precision casting and have a special coating highly resistant to external influences. Trunks have polygonal rifling. The trigger mechanism is a striker, with a preliminary cocking of the mainspring and its additional cocking by the shooter's muscular strength at the moment the trigger is pressed. To pre-cock the mainspring, it is enough to pull the bolt back about 15mm and release it. The gun does not have non-automatic (manual) fuses. The system of automatic fuses (safeaction) includes a safety on the trigger (blocking its movement if it is pressed incorrectly), blocking the drummer when the trigger is not pressed, and blocking the drummer from breaking off the sear during strong blows. The frame of the pistol is made of high-impact plastic in black or (more recently) olive green. Steel guides for the slide are integrated into the frame when it is cast, as well as a small metal plate on which the serial number of the weapon is engraved. In front of the frame of modern pistols there is a guide for attaching a combat flashlight or a laser designator. Sights are open, with white contrasting or luminous inserts. Glock pistols with the index "C" after the model number have a barrel toss compensator, made in the form of upward holes in the muzzle of the barrel and the shutter casing. On the frame above the trigger guard on both sides there are sliders, when pressed down, the pistol is partially disassembled (removal of the barrel, return spring and bolt from the frame). Cartridges are fed from box-shaped double-row plastic magazines with cartridges exiting in one row (with the exception of the most compact models 36 and 42, which have single-row magazines).

The Glock 18 automatic pistol differs from the basic Glock 17 model by the presence of a fire mode translator on the left on the shutter. For this pistol, extended magazines with a capacity of 33 rounds have been developed and are being produced, also compatible with 9mm Glock pistols models 17, 19 and 26.

Several decades ago, the Austrian armed forces were equipped with two models of handguns, some of which were issued during the Second World War, and some even before it. Model 11 is the Austrian designation for the automatic pistol Colt M 1911 A1 (USA), and model 38 is the name used in Austria for the Walter R 38 automatic pistol from Germany.

In the mid-seventies, the Austrian armed forces announced a tender among local and foreign firms for the production of new standard handguns. They needed a modern pistol that would meet the following requirements: the ability to quickly prepare for battle without the need to actuate a lever or fuse; maximum possible safety for the user and large magazine capacity.

Many enterprises from Austria and other countries took part in the competition, and when the decision was made, the specialists were extremely surprised. It was not an eminent manufacturer that won, but an Austrian enterprise completely unknown in the field of development and production of weapons. Until that time, the company produced only plastic and metal products and was known only for the supply of bayonet shovels and belts for machine guns for the army. But Gaston Glock, director of the family business, by developing the Glock 17 automatic pistol, was ahead of all competitors.

And one more circumstance surprised the experts. The Glock pistol, which was loaded with 9x19 Parabellum cartridges and had a magazine capacity of 17 rounds (which gave the pistol its name), was not generally intended for military use, but was designed as a civilian weapon for free sale. After the company received subsidies in May 1980, the designers began developing some prototypes that could be used for military purposes.
In May 1982, after appropriate tests, the Austrian military ordered 25,000 copies of the Glock 17 pistol for the army.

The gun was made mainly of plastic and therefore had a small mass. For example, the handle, due to its rough surface, is very comfortable in the hand and is made by flame spraying of polyamide artificial resin. In the production of parts that are subjected to the greatest load, plastic parts were reinforced with steel plates. The bolt body and barrel are made of steel.
The Glock 17 automatic pistol can be used for single fire, and the action of its automation is based on the use of the recoil energy of the moving barrel. The supply of Parabellum 9x19 cartridges is carried out from a two-row magazine, which is made of plastic. Shooting is carried out on the principle of single action. Designers and manufacturers have equipped their weapons not with an external trigger, but with a firing pin, which is automatically cocked when reloading and moving the bolt forward after a shot. Thus, in order to shoot, the shooter only needs to pull the trigger.
The trigger resistance is approximately 3 kg, and its free travel is 5 mm. The resistance and trigger path remain the same with each shot, which guarantees accurate shooting. Aiming even in poor visibility is also easy. sighting device made of plastic.

Despite the fact that our fellow citizens will not see personal short-barreled weapons for self-defense for a long time, you need to be able to understand it at least a little. Let theoretically, let it be at the level of “click here, shoot there”, but it is necessary. You never know exactly how life will turn out ... And so we will tell you something interesting about Glock pistols.

Why Glock? Oh, there are as many as 7 reasons for this, or rather, myths that only grow around. So…

1. Glock pistols are the most common handguns in the world.

Partly true. Yes, Glocks are very fond of law enforcement officers. The same Glock 17 and its various variations are in service with the law enforcement forces of Norway, Austria, Canada, Mexico, the USA and a bunch of other NATO countries. Not to mention America, where Glock pistols are generally a ubiquitous phenomenon.

But other brands can boast of the enviable popularity of their pistols. We are talking about arms companies CZ (Czech Republic), Beretta and Tanfoglio (Italy), Walther and Heckler & Koch (Germany), FN (Belgium) and Colt (America).

In Russia, among the “siloviki”, the APS pistols (Stechkin automatic pistol), PYa (Yarygin pistol) and PM (Makarov pistol) are extremely popular, and the Glock pistol is only gaining momentum.

2. The Glock is missing a fuse

This is perhaps the main feature of the pistol. The Glock has three safety locks (on the trigger, on the drummer and shockproof), and they are all automatic. In order to start shooting, you do not need to intentionally press the button or switch the fuse box, the protection system will work automatically.

And this is also the reason why Glock pistols are categorically not recommended for beginners, so that they don’t shoot something for themselves.

Glock is well suited for people who use weapons for work or for sports, and train daily for several hours. The same law enforcement officers are honing their skills in using the Glock to automatism. And they are very pleased with the absence of the need to make unnecessary movements to remove the gun from the safety.

3. Glock is invisible to metal detectors

Lies, of course, but there is a grain of truth here. The Glock is indeed quite poorly viewed on detectors, since half of the construction is heat-resistant plastic. At least the latest models.

Here are just a recognizable outline of the weapon, which is visible on the detector screen, is still preserved. Plus, it hasn’t worked out yet, so it will “ring” like any other weapon. And the myth that it can still be carried unnoticed appeared after the release of the film "Die Hard 2" and Bruce Willis's phrase about it.

4. Because of the plastic, the Glock pistol weighs too little

Yes, the gun is relatively light, but not too light. Simplifying the design main reason why they started using heat-resistant plastic. He really significantly reduced the weight of the gun, while maintaining the proper level of strength.

Discharged Glock 17 weighs about the same as three full ammunition for it - 51 rounds of 9x19 caliber. These are 649 and 612 grams, respectively. When fully loaded, the pistol weighs 941 grams (pistol with magazine and 18 rounds). Which is comparatively more than that of PM. But given the greater power, it is quite logical.

5. The plastic that Glock pistols are made of is brittle and short-lived.

And this myth is almost the opposite of the previous one. The official name for the plastic used in the production of Glocks is Polymer 2. There is information that this is just an alternative name for another material - DuPont's Glass-Reinforced Zytel® Nylon. Which is used, among other things, for the production of particularly durable sneakers. So far, no one has been able to refute this information.

6. The Glock has an extremely complex design and a lot of parts.

base model Glock 17 consists of only 34 components. For comparison, the same PM of the constituent parts has 32 positions. That is, Glock pistols are very easy to disassemble and maintain.

And given the fact that Western gunsmiths gravitate more towards reliability at the expense of complexity, the Glock was almost a revolutionary concept.

7. Glock is dangerous, it is very easy to get a random shot from it.

Partly true, but remember that "guns don't kill, people do."

Yes, the lack of a mechanical fuse can play a trick on the shooter. Gaston Glock himself, after creating experimental models, preferred to work with a new pistol, using only one hand - the left. That is, recharge, and pick up, and clean. The gunsmith rightly feared that even accidentally pulling the trigger could provoke a shot.

Novice Glock users are also afraid of this, but with practice, the fear goes away pretty quickly.

Glock 17 (Glock 17) is an Austrian pistol developed by Glock for the needs of the Austrian army. He became the first type of weapons developed by this company. The resulting sample turned out to be quite successful and convenient to use, thanks to which it was later adopted by the Austrian army under the designation P80. Due to its combat qualities and reliability, it has become widely used as a civilian weapons self defense.

Glock 17 pistol - video

Glock produces modifications of this pistol in various versions for different cartridges, for example: 9 × 19 mm Parabellum Glock 19, .40 S&W - Glock 22, 10 mm Auto - Glock 20, .357 SIG - Glock 31, .45 ACP - Glock 36 and .45 GAP - Glock 37.

A design feature of the pistol is the absence of a fuse box and a trigger. The gun is mostly made of high-strength heat-resistant - up to 200 ° C - plastic. This makes the Glock 17 lightweight and extremely durable. The principle of operation is “grab and shoot”, there is no fuse, however, the shot will not occur without fully pressing the “safe action” trigger. It consists of 33 parts, and partial disassembly is carried out in seconds.

Story

After the end of World War II, the Austrian armed forces were armed with two main models of pistols Colt M1911A1 and Walther P38. The Austrian police were equipped with Walther PP and Walther PPK military and even pre-war years of production or released in the post-war years under license in France. To resolve the situation in 1980, it was decided to announce a competition for a new pistol to equip the Austrian police and army.

The following requirements were imposed on the contestants:

Ammunition type: 9x19mm Parabellum;
— minimum magazine capacity: 8 rounds;
- the ability to control the gun with the right and left hand;
- quick bringing into combat position (without the need to switch the fuse);
- the possibility of assembly and disassembly without special equipment, the number of parts in the gun - no more than 58;
- all parts must be interchangeable within the same model without mutual adjustment;
- for 10,000 shots there should be no more than 20 delays;
- the gun should preserve the integrity and functionality as much as possible under external influences and temperature changes;
- maximum safety for the user: the shot should not occur when hitting a steel plate after falling from a height of 2 meters.

Various weapons manufacturers took part in the struggle for such a promising order. Among them was the then little-known company Glock, founded in 1963 in the town of Deutsch-Wagram, located near Vienna. At that time, the company was engaged in the production and supply of sapper shovels, bayonet-knives, belts and various ammunition for the Austrian army. Back in the mid-1970s, Gaston Glock, the founder and owner of the company, set the task of creating the simplest, most effective and reliable pistol for his designers.

Using the existing experience in the use of polymers in the manufacture of weapons, the Glock 17 pistol was created. The fundamental innovation of this model was the widespread use of polymer materials in its design, mainly impact-resistant polyamide was used. In 1982, according to the results of military tests, the Glock 17 pistol was adopted by the Austrian army under the designation P.80. Glock was ordered 25,000 pistols, production facilities were not ready for such a significant order, therefore, until the full deployment of their own production capacity subcontractors were involved.

Around the same time, the pistol was presented along with samples from other manufacturers to participate in the competition called "M9" for the re-equipment of officers and non-commissioned officers of all branches of the US armed forces with personal service weapons (in the end, the Beretta model won).

Pistols submitted to the M9 competition

Soon after the arrival of the new pistol to the Austrian troops, this model gained considerable popularity, which prompted the Glock company to further expand and improve the model range, but at the heart of the design existing models The pistols of this company still retain those successful technical solutions that were first successfully used in the development of the Glock 17 pistol.

The name "Glock 17", the pistol, most likely owes to the serial number (No. 17) of the package of technical drawings of the company, eventually accepted for production.

Production generations and variants

To date, there are four production generations of the Glock 17. Buyers are offered a choice of third or fourth generation pistols, the same applies to most other Glock models, but some models (Glock 17L, Glock 24, Glock 25, Glock 28, Glock 36, Glock 38, Glock 39, Glock 42, Glock 43) are offered only in the third generation, and some (Glock 40 and Glock 41) only in the fourth.

First generation

Pistols of this generation were produced until 1988, mainly for the Austrian army. They were distinguished by a handle with a uniformly distributed rough texture. In total, about 500,000 copies were produced.

Second generation; second and a half generation

The second generation Glock appeared in late 1988, early 1989. On the front and rear surfaces of the handle, corrugations began to be made in the form of small square protrusions forming horizontal and vertical lines, which increased the reliability of holding the pistol in the hand. The same corrugation is available on the front surface of the trigger guard. The second generation pistols were adopted by the FBI, the Finnish police, the armies of Norway and the Netherlands. After some time, sub-finger recesses began to be made on the front surface of the handles, this option was designated generation 2.5. Some authors prefer to call this frame an early version of the third generation.

third generation

The third generation, in addition to the corrugation and sub-finger recesses, also received a mount for underbarrel flashlights and laser designators, and in addition, an additional (second) pin that fixes the locking block (a metal insert in the case with a cross member, which, interacting with the figured cutout of the tide of the breech breech, leads to its lowering, and as a result - the disengagement of the barrel from the bolt). This change was made so that the locking block could withstand the recoil of the powerful .357 SIG rounds introduced from this generation. Although the 9 mm models did not need such a reinforcing pin, for unification technological processes they got it too. In the upper part of the handle, they began to make a recess for the thumb, bounded from below by an elongated protrusion.

As an option, third generation pistols are available in RTF2 (Rough Textured Frame). The handle of the pistol in this version is covered with convex points that increase the reliability of holding the weapon, including if it is wet. There are 64 points per square centimeter of the RTF2 frame surface. On the other hand, the constant wearing of a pistol in this version, for example in an underarm holster, leads to accelerated wear of the fabric of clothing in contact with the handle. In this regard, RTF2, for all its merits, is unattractive for professional bodyguards working in expensive suits.

fourth generation

The fourth generation has the most significant innovations among all existing generations. The handle is standard RTF, but compared to the RTF2 pistols of the third generation, there are larger gaps between the points - 25 points per cm², instead of 64 for the RTF, and the points themselves are larger.

The back of the handle is made in the form of a separate interchangeable part called the "back plate" (back strap). A part of the minimum size SF (short frame) is installed as standard, in this case the distance from the back of the handle to the trigger is 70 mm. The gun comes with two additional parts M (medium) and L (large), which can be installed instead of the standard one. Detail M increases the distance to the trigger up to 72 mm, L - up to 74 mm. Thus, they allow better grip ergonomics for shooters with longer fingers. To change the part, you need to remove the mounting pin, for which a special tool is provided in the kit.

The store latch button has become larger and more convenient. It also became possible to rearrange it to the right side (more convenient for left-handed shooters). In this regard, a second window appeared on the magazines of the fourth generation pistols under the latch tooth, on the right side. pistol shops previous generations can be used in fourth generation pistols, but only if the button is set to the left.

Instead of one return spring, fourth-generation pistols began to install two springs of different diameters (on the same guide rod). In this case, the load arising from recoil is distributed more evenly, the survivability of each individual spring increases, and the recoil felt by the shooter decreases.

Unlike previous generations, the fourth has a corresponding marking on the shutter - Glock 17 Gen4.

Design

This type of pistol is a fairly simple and reliable design, consisting of 33 parts and can be disassembled without the help of special equipment.

Pistol automation

The automatics of the Glock 17 pistol work according to the scheme of using recoil with a short barrel stroke. The design used a modernized system Colt-Browning (Brauning Cam), which is a modernization of the Browning earring. Under the breech, a tide is made with an inclined groove, coinciding with the guide ledge of the frame. The groove is made at such an angle that, moving along the ledge, it causes the moving barrel to decrease, due to which the latter disengages from the shutter-casing, and then stops, allowing the shutter to roll back unhindered.

The barrel bore is locked by means of a descending breech, which enters with its rectangular protrusion located above the chamber into the window for ejection of spent cartridge cases of the shutter-casing. The decrease occurs when the bevel of the lower tide of the breech breech interacts with the protrusion of the frame. After the shot, the bolt, moving backward, bends the uncoupler, thereby releasing the thrust, which then rises under the action of the thrust spring. When the bolt moves forward, the striker's hook encounters the thrust hook and returns the trigger through the thrust to the forward position. In this case, the drummer is pre-cocked. Pistols of the latest releases are equipped with an ejector, which also acts as an indicator of the presence of a cartridge in the chamber.

trigger mechanism

The trigger mechanism (USM) of the striker type with a preliminary partial cocking of the drummer when the shutter-casing moves back and additional cocking when the trigger is pressed. When the trigger is pressed, the firing pin block is first removed, then the sear releases the combat platoon, and a shot is fired. Glock calls the trigger of this design only self-cocking (DAO). However this system in fact, it is a classic single-action trigger with an additional firing pin.

In Glock pistols, the drummer is cocked by moving the shutter-casing back, and the relatively long trigger stroke and slightly more than a conventional single-action trigger, the force required to cock the drummer, replace the manually controlled fuse. To ensure maximum ease of handling weapons in the design of this pistol, it was decided to abandon the use of manual safety catches, only automatic ones were left, which made it possible to significantly reduce the time interval from the moment the pistol was removed to the moment the fire was opened.

In the absence of cartridges, the shutter delay is turned on, fixing the shutter in the allotted position. The length and force of the stroke in this case prevent random shot in the absence of a flag fuse. The trigger pull is 2.5 kg and can be adjusted from 2 to 4 kg. A small effort required to pull the trigger allows you to increase the accuracy of fire even for a poorly trained shooter.

Circuit breakers

The gun is equipped with three independently operating automatic safety locks. Glock called this system Safe Action. The safety lever, which is equipped with the trigger, blocks its movement back and releases it only when the shooter is consciously pressed. The automatic fuse of the striker makes it impossible for the striker to hit the primer of the cartridge in the event of an accidental failure from the cocking sear. The trigger rod, with its special protrusion, raises the fuse, which is a cylinder with a groove, and opens the way forward for the drummer. The shockproof fuse is a protrusion of the trigger rod, which has a cruciform shape, which is included in the groove of the shutter-casing. It prevents the combat platoon from falling off the sear during an external impact.

Sights

The sights of Glock pistols, made of plastic, are removable and installed in transverse dovetail grooves, consist of a rear sight with the possibility of making horizontal adjustments by shifting it and a front sight, which can be replaced with another one with a different height for vertical correction. For ease of aiming in low light conditions, a luminous dot is applied to the front sight, and a luminous frame is applied to the rear sight. The rear sight can be adjustable, but this is not usually the case in military models. Since 1988, pistols of this model in most cases are equipped with a special guide for attaching a laser target designator (LTC) or a tactical flashlight.

Design features

The gun has a simple and reliable design. When completely disassembled, it consists of 33 parts, including a magazine. Maintenance can be carried out without the use of special equipment using improvised means, which greatly facilitates maintenance and repair. Equipped as standard with a 17-round magazine; can also use magazines with a capacity of 19 and 33 rounds. In addition to the generally accepted design features, the Glock 17 also has a number of specific technical solutions that were then used in pistols of subsequent models.

Many parts of the pistol were created using polymer materials, including the frame (except for the barrel and bolt cover), which made it possible to reduce the weight of the weapon to 900 g in running order (for comparison: the weight of the Beretta 92 pistol with a magazine of 15 rounds is 950 g . in unloaded state). Moreover, the mass of the equipped store in the Glock 17 is 250 g, that is, about 25% of the weight is ammunition.

A distinctive feature of Glock pistols is also the high survivability of components and mechanisms. On average, a pistol is considered wear-resistant if it can fire about 30-40 thousand shots, and 300-350 thousand shots can be fired from the Glock 17. Such superiority in wear resistance is due to the extensive use of polymer parts and the unique barrel manufacturing technology patented by Glock.

The outer body and frame can be made of plastic in various colors. The most famous is classic black, there is also a Glock 17 in camouflage. In the production of parts subjected to the greatest stress, the plastic is reinforced metal plates. The guide frames along which the shutter casing moves are reinforced with steel inserts. At the bottom of the frame is a small metal plate stamped with the gun's factory serial number. On the pistol frame above the trigger guard on both sides there are latches, when pressed, incomplete disassembly of the pistol, removal of the bolt barrel and return spring from the frame becomes available.

Shooting underwater

An interesting feature of Glock pistols is the ability to fire underwater. In this case, not only rupture, but also swelling of the trunk does not occur. However, for stable operation of the primer, a special striker with transverse grooves or a set of Spring cups amphibia is required: the mainspring of the striker with a plastic pallet with holes. Available only for pistols chambered in 9 mm Parabellum. However, for firing under water without the risk of barrel swelling, the use of cartridges with FMJ-type full-shell bullets is recommended. Glock pistols can be fired underwater at depths up to three meters. The bullet retains great energy at a distance of up to two meters when fired at a depth of one meter. Shooting at close range from under the water is also effective, while the sound of the shot is not audible.

Existing modifications manufactured by Glock

The Glock 17 pistol served as the basis for the entire range of pistols manufactured by Glock. Glock pistols, which have the “C” index in the model designation, are equipped with a built-in compensator, made in the form of several upwardly directed holes located at various intervals in the muzzle of the barrel, and an elongated cutout in the upper part of the casing-bolt. The presence of this device made it possible to reduce the recoil when fired, which somewhat increased the accuracy of fire.

Usage

Due to its successful design, the pistol has become widespread throughout the world. Various modifications of the Glock 17 pistol are in service with the army and police in more than 30 countries, such as Austria, Sweden and Norway. The model was approved by the NATO leadership as one of the main models of small arms, "Glocks" of various modifications are in service with the police and intelligence agencies of the United States, Canada, Mexico, India, the Philippines, Saudi Arabia and many other countries.

This pistol is a typical self-defense weapon. Maximum effective range shooting is 50 m, effective shooting at such a distance requires a good shooting training and experience with weapons that are fired from. On average, the Glock 17 is most effective at a distance of 20-25 m, due to the fact that even a poorly trained shooter is able to hit a target at such a distance. The muzzle velocity of a bullet fired from a Glock 17 at the muzzle is 350-360 m/s. The muzzle energy is about 500 J. These characteristics determine the scope of this weapon model.

The energy of a bullet of 350-400 J is enough to inflict serious injury upon impact. The 9mm bullet has a pronounced stopping effect, which allows the shooter to inflict incapacitating, but not fatal, wounds. This quality is especially necessary for police and intelligence officers in cases where you need to stop the target, but there is no need to kill him. In the event that the enemy is protected by body armor, hitting the chest plate of the armor leads to strong concussion, and in some cases to loss of balance, which gives the shooter time to transfer fire to parts of the body that are not protected by armor.

Glock 17 can be effectively used in almost all climatic zones, with the exception of the Far North and zones with a sharply continental climate, in which the air temperature can drop below -40 ° C. This is due to its design features. Due to the wide use of polymers, this model is not afraid of the traditionally dangerous for pistols high humidity, dust, jungle and rainforests. But under conditions low temperatures the plastic frame of the pistol turns from an advantage into a disadvantage due to the increased fragility of the plastic; the components and assemblies of the pistol fail faster, and without proper regular maintenance with the replacement of plastic components in a critical situation, the pistol may not be combat-ready.

The initial velocity of the bullet, like all pistols, is relatively low, which limits the effective range of 50 m.

In law enforcement forces, the Glock 17 is used as the main weapon on peacetime patrols.

In army structures, the Glock 17 is an additional weapon for officers, in some cases sergeants. They can also arm the crews of vehicles. In combat conditions, the Glock 17 is effective for self-defense when it is impossible to use the main weapon.

It is thanks to the fact that the Glock 17 effectively copes with the tasks in all three main areas of its application that it has become so widespread in the world.

Advantages of the Glock 17 pistol

High resistance to corrosion, thanks to the use of a special patented Glock technology for processing barrels and a large number of polymer parts.
- Smooth recoil and high accuracy of fire due to the use of a large number of polymer parts.
- Less weight than pistols of the same class due to the manufacture of the body and frame of the pistol from plastic.
- High wear resistance of units and mechanisms. The barrel before burning out allows you to make 300-350 thousand shots (for other pistols, on average, this value is 40-50 thousand shots).
- Bringing into combat position does not require switching any fuse.
- Declared by the manufacturer the possibility of firing at aquatic environment without damage to the gun when changing the return spring.
- The gun can be easily disassembled for cleaning and maintenance without the use of special equipment.
- Ability to use stores with a large number of rounds.
- This pistol has a comparatively larger handle slope than other pistols, which makes shooting more comfortable.

Disadvantages of the Glock 17 pistol

There is a possibility that when carried in a pocket for a long time without regular maintenance, small debris can jam the firing pin release lever, making it impossible to fire. But, according to some sources, this event is too unlikely to affect the actual combat capability of the pistol.
- Shutter guides, having a small area, wear out quickly, which leads to a gradual deterioration in accuracy and accuracy of fire due to the rocking of the bolt frame.
- Low resistance of important pistol components to high rates of fire.
- With prolonged use, microcracks in plastic almost inevitably appear.
- The standard front sight is too wide and covers the target.
- Like all pistols with a plastic frame, it requires a confident hold of the weapon to ensure the operation of the automation.
- The trigger mechanism does not allow re-pricking the cartridge primer in the event of a misfire - you need to pull the bolt. The disadvantage is conditional, with a small number of cartridges. In general, when shooting, the cause of a misfire is not important - the way to eliminate it is important. In the presence of cartridges, it is easier to pull the bolt than to cock an open trigger, not knowing whether the striker will prick the primer of this cartridge, provided that it has not been pricked for the first time.
- Due to the use of polymer materials, the Glock becomes more brittle at temperatures below -40 ° C, which can lead to cracks in the receiver and frame under mechanical stress. At high temperatures - over 200 °C - deformations of the plastic components of the pistol may occur. In the technical recommendations of the Glock company, the operating temperature range is specified from -40 to 200 ° C, the use of a gun outside this temperature range can lead to failure of its main components and structural components.

Curious facts

A widely advertised feature of the Glock 17 is its ability to fire under water when retrofitting the pistol with a special reinforced return spring. This effect is achieved due to the strength of the barrel and simple and reliable automation that does not use complex gas exhaust systems, and replacing the standard return spring with a reinforced one allows you to return the bolt back to the firing position even with a significantly increased environmental resistance. The practical value of this ability is low - this is due to the fact that in water the energy of the bullet is extinguished very quickly due to the high density of the medium, and the effective firing range does not exceed 1-2 meters. But despite the low efficiency of the pistol in this situation, the very presence of this ability indicates the high reliability and wear resistance of components and mechanisms, the preservation of the combat capability of the Glock 17 in conditions of any, arbitrarily high humidity, and even the ability to fire when there is water in the barrel bore , which for many other models of pistols can lead to barrel deformation or serious damage to the components and parts of the weapon.
