Glock and its Variants With full Details

The Glock pistol, sometimes referred to by the manufacturer as a Glock "Safe Action" pistol and colloquially as a Glock, is a series of polymer-framed, short recoil-operated, locked-breech semi-automatic pistols designed and produced by Glock Ges.m.b.H., located in Deutsch-Wagram, Austria. It entered Austrian military and police service by 1982 after it was the top performer on an exhaustive series of reliability and safety tests. Despite initial resistance from the market to accept a perceived "plastic gun" due to unfounded durability and reliability concerns and fears that it might circumvent metal detectors in airports, Glock pistols have become the company's most profitable line of products, commanding 65% of the market share of handguns for United States law enforcement agencies as well as supplying numerous national armed forces, security agencies, and police forces in at least 48 countries.Glocks are also popular firearms among civilians for recreational and competition shooting, home and self-defense, and concealed carry or open carry. Variants:- Following the introduction of the Glock 17, numerous variants and versions have been offered. Variants that differ in caliber, frame, and slide length are identified by different model numbers with the exception of the Glock 17L. Other changes not dealing with frame and slide length are identified with suffixes, such as "C", which denotes compensated models.non-primary source needed Minor options such as frame color, sights, and included accessories are identified by a separate model code on the box and do not appear anywhere on the firearm. Glock pistols are made in five form factors, all modeled after the original full-sized Glock 17. "Standard" models are designed as full-sized duty firearms with a large magazine capacity. "Compact" models are slightly smaller with reduced magazine capacity and lighter weight, while maintaining a usable grip length. "Subcompact" models are designed for easier carry, and being lighter and shorter, are intended to be used with two fingers on the grip below the trigger guard, and lack an accessory rail like the larger, after generation two, Glock models. The .45 ACP and 10mm Auto models have bigger, wider slides and are slightly larger than the smaller-chambered pistols and are available in the subcompact models Glock 29 (10mm) and Glock 30 (.45 ACP). Glock produces three models of single-stack "Slimline" subcompact pistols, the Glock 36 in .45 ACP, the Glock 42 in .380 ACP, and the Glock 43 in 9 x19 mm. "Competition" versions have longer barrels and slides, adjustable sights, an extended slide and magazine release. Beginning in 2007, Glock introduced several "Short Frame" models designated by the suffix "SF". The short frame was originally designed to compete in the now cancelled U.S. military Joint Combat Pistol trials for a new .45 ACP pistol to replace the M9 pistol. Glock's entry featured an optional ambidextrous magazine release and MIL-STD-1913 rail along with a reduction in the size of the backstrap. The Glock 21SF is currently available in three versions: one with a Picatinny rail and ambidextrous magazine release and two with a Universal Glock rail available with or without the ambidextrous magazine release. Current 10 mm and .45 ACP Glock magazines are manufactured with ambidextrous magazine release cutouts. As of January 2009, the Glock 20, 21, 29, and 30 were offered in short-framed variations. These models incorporate a 2.5 mm (0.098 in) reduction in trigger reach, and full-sized models feature a 4 mm (0.16 in) reduction in heel depth, which corresponds to an overall reduction in length for those models. 9×19mm Parabellum The Glock 17 is the original 9×19mm Parabellum model, with a standard magazine capacity of 17 rounds, introduced in 1982. Several modified versions of the Glock 17 have been introduced: The Glock 17L, introduced in 1988, incorporates a longer slide and extended barrel. Initially, the Glock 17L had three holes in the top of the barrel and a corresponding slot in the slide; however, later production pistols lack the holes in the barrel. The Glock 17L is manufactured in limited quantities. The Glock 17C, introduced in 1996, incorporates slots cut in the barrel and slide to compensate for muzzle rise and recoil. Many other Glock pistols now come with this option, all with a "C" suffix on the slide. The Glock 17MB is a version with ambidextrous magazine catch. This model, along with the other MB variants, was discontinued upon the introduction of the fourth-generation models, which have a reversible magazine catch. The Glock 17M, introduced in 2016, was created in response to an FBI solicitation for a new 9mm pistol. Differences from the Generation 4 model include removal of the finger grooves, ambidextrous slide lock, rounded slide nose profile, flared magwell with new magazine baseplates, and a tougher finish on metal components. The Glock 17M also abandons the polygonal rifling of previous models for conventional rifling.As of 2017, the Federal Bureau of Investigation. the South Carolina Highway Patrol and the Canadian Ontario Provincial Policehave adopted the pistol as standard. The Glock 18, chambered in 9×19mm Parabellum, fitted with a detachable shoulder stock being fired in fully automatic mode The Glock 18 is a selective-fire variant of the Glock 17, developed at the request of the Austrian counter-terrorist unit EKO Cobra, and as a way to internally test Glock components under high strain conditions.[67] Originally produced in 1986, this machine pistol–class firearm has a lever-type fire-control selector switch, installed on the serrated portion of the rear left side of the slide. With the selector lever in the bottom position, the pistol fires fully automatically, and with the selector lever in the top position, the pistol fires semiautomatically. The firearm is typically used with an extended 33-round-capacity magazine, although other magazines from the Glock 17 can be used, with available capacities of 10, 17, or 19 rounds. Unlike all its other pistols, Glock is highly secretive about Glock 18 models, not including them on its official websites or its public catalogues,and because of the pistol's nature, it is only offered to military, law enforcement and government organizations,and its production details are highly classified. Early Glock 18 models were ported to reduce muzzle rise during automatic fire. A very early design introduced a longer ported barrel which was soon discarded as it would not fit in a holster. Another compensated variant was produced, known as the Glock 18C. It has a keyhole opening cut into the forward portion of the slide, similar to the opening on the Glock long-slide models, although the Glock 18 has a standard-length slide. The keyhole opening provides an area to allow the four, progressively larger (from back to front) compensator cuts machined into the barrel to vent the propellant gases upwards, affording more control over the rapid-firing machine pistol. The compensator cuts start about halfway back on the top of the barrel. The two rear cuts are narrower than the two front cuts. The slide is hollowed, or dished-out, in a rectangular pattern between the rear of the ejection port and the rear sight. The rate of fire in fully automatic mode is around 1,100–1,200 rounds per minute. Most of the other characteristics are equivalent to the Glock 17, although the slide, frame, and certain fire-control parts of the Glock 18 are not interchangeable with other Glock models. The compact Glock 19 in 9×19mm Parabellum The Glock 19 is effectively a reduced-size Glock 17, called the "Compact" by the manufacturer. It was first produced in 1988, primarily for military and law enforcement. The Glock 19's barrel and pistol grip are shorter by about 12 mm (0.5 in) than the Glock 17, and it uses a magazine with a standard capacity of 15 rounds. The pistol is compatible with factory magazines from the Glock 17 and Glock 18, giving the Glock 19 available capacities of: 17 rounds (standard magazine with +2 extension), 10, 17, and 19 (standard Glock 17 magazine with +2), and the 31 (standard Glock 18 magazine with +2 removed) and 33 rounds of the Glock 18. To preserve the operational reliability of the short recoil system, the mass of the slide remains the same as in the Glock 17 from which it is derived. With the exception of the slide, frame, barrel, locking block, recoil spring, guide rod, and slide lock spring, all of the other components are interchangeable between the models 17 and 19. The subcompact Glock 26 with tritium night sights in 9×19mm Parabellum The Glock 26 is a 9×19mm "subcompact" variant designed for concealed carry and was introduced in 1995, mainly for the civilian market. It features a smaller frame compared to the Glock 19, with a pistol grip that supports only two fingers, a shorter barrel and slide, and a double-stack magazine with a standard capacity of 10 rounds. A factory magazine with a +2 extension gives a capacity of 12 rounds. In addition, factory magazines from the Glock 17, Glock 18, and Glock 19, with capacities of 15, 17, 19, 31 and 33 rounds, will function in the Glock 26. More than simply a "shortened" Glock 19, design of the subcompact Glock 26 required extensive rework of the frame, locking block, and spring assembly that features a dual recoil spring. The Glock 34 is a competition version of the Glock 17. It is similar to its predecessor, the Glock 17L, but with a slightly shorter slide and barrel, to meet the maximum size requirements for many sanctioned action pistol sporting events. It was developed and produced in 1998, and compared to the Glock 17, features a 21 mm (0.8 in) longer barrel and slide. It has an extended magazine release, extended slide stop lever, 20 N (4.5 lbf) trigger pull, and an adjustable rear sight. The sides at the front of the slide are slanted instead of squared. Further, the top of the slide and parts of its inside are milled out, creating a conspicuous hole at the top designed to reduce front-end muzzle weight to better balance the pistol and reduce the overall weight of the slide. The Glock 43 is a "slimline" version of the subcompact Glock 26 that features an ultracompact slide and frame. The Glock 43 is the first Glock pistol to be manufactured with a single-stack 9×19mm Parabellum magazine, having a standard capacity of six rounds and being unique to the model. Unlike other subcompact Glock pistols, the Glock 43 cannot use factory magazines from its larger relatives due to its single-stack magazine design. It also does not allow the removal of the backplate grip as is possible on the 4th gen Glocks. 10mm Auto.The subcompact third-generation Glock 29 in 10mm Auto The Glock 20, introduced in 1991, was developed for the then-growing law enforcement and security forces market for the 10mm Auto. The pistol handles both full-power and reduced "FBI" loads that have reduced muzzle velocity. Due to the longer cartridge and higher pressures, the pistol is slightly larger than the Glock 17, having a roughly 2.5 mm (0.1 in) greater width and 7 mm (0.3 in) greater length. Though many small parts interchange with the Glock 17, with a close to 50% parts commonality, the major assemblies are scaled-up and do not interchange. The standard magazine capacity of the Glock 20 is 15 rounds. In 2009, Glock announced they would offer a 152 mm (6.0 in) barrel as a drop-in option. The Glock 20SF is a version of the Glock 20 that uses the Short Frame (SF) which is based on the standard G20 frame (same width), but reduces the trigger reach from the back of the grip by 2.5 mm (0.098 in) and the heel of the pistol is shortened by 4 mm (0.16 in) so the trigger can be reached and operated better by users with relatively small hands. The Glock 29 is a 10mm Auto equivalent of the subcompact Glock 26 introduced in 1997 along with the Glock 30 (.45 ACP). The pistol features a 96 mm (3.8 in) barrel and a standard magazine capacity of 10 rounds. Like other subcompact Glock pistols, the Glock 29 functions with the factory magazines from its related full-size model, giving an optional capacity of 15 rounds. The Glock 29SF version of the Glock 29 uses the SF which is based on the standard G29 frame (same width), but reduces the trigger reach from the back of the grip by 2.5 mm (0.098 in). The Glock 40, introduced in 2015, is a 10mm Auto equivalent of the long-slide Glock 17L. The Glock 40 is only made with the "Gen4" frame and "MOS" (Modular Optic System) configuration..45 ACP. The slim-frame Glock 36 in .45 ACP Glock pistols chambered for the .45 ACP (and the .45 GAP) feature octagonal polygonal rifling rather than the hexagonal shaped bores used for models in most other chamberings.Octagonal rifling provides a better gas seal in relatively large diameter rifled bores, since an octagon resembles a circle more closely than a hexagon. The Glock 21 is a .45 ACP version of the Glock 20 designed primarily for the American market.Compared to the Glock 20 chambered in 10mm Auto, the slide of the Glock 21 is lighter to compensate for the lower-energy .45 ACP cartridge. The standard Glock 21 magazine is of the single-position-feed, staggered-column type with a capacity of 13 rounds. The Glock 21SF is a version of the Glock 21 that uses a Short Frame lower which is based on the standard G21 frame (same width), but reduces trigger reach from the back of the grip by 2.5 mm (0.098 in), and the heel of the pistol is shortened by 4 mm (0.16 in) so the trigger can be reached and operated better by users with smaller hands. The Glock 30 is a .45 ACP version of the subcompact Glock 29, with a standard magazine capacity of 10 rounds. The factory magazine from the Glock 21, with a capacity of 13 rounds, will function in the Glock 30. The Glock 30SF is a version of the Glock 30 that uses a Short Frame lower which is based on the standard G30 frame (same width), but reduces trigger reach from the back of the grip by 2.5 mm (0.098 in). The G30SF accepts the same double-stack .45ACP magazines as the G30 and G21. The Glock 30S is a version of the Glock 30 that features a thin slide (same slide as the G36), a Short Frame lower, and a double stack magazine. Like the G30, G30S magazines holds 10 rounds. The Glock 36 is a "slimline" version of the subcompact Glock 30 that features an ultracompact slide and frame and is chambered for the .45 ACP cartridge. The Glock 36 is the first Glock pistol to be manufactured with a single-stack magazine, having a standard capacity of six rounds and being unique to the model. The Glock 36 cannot use factory magazines from its larger relatives due to its single-stack magazine design. The Glock 41 is a competition version of the Glock 21, much like what the G34 is in relation to the G17; it features a 5.3-inch barrel and an elongated slide. The Glock 41 is only made with the "Gen4" frame. .40 S&W Glock 22 OD in .40 S&W with olive drab frame The competition-oriented Glock 35 in .40 S&W The Glock 22 is a .40 S&W version of the full-sized Glock 17 introduced in 1990. The pistol uses a modified slide, frame, and barrel to account for the differences in size and power of the .40 S&W cartridge. The standard magazine capacity is 15 rounds. The Glock Model 22 is favored and used by several police agencies around the world, including the Baltimore Police Department, Los Angeles Police Department, Miami Police Department, Maryland State Police, Kansas City Police Department, Missouri State Highway Patrol, Alaska State Troopers in the United States, and the NSW Police Force and Queensland Police Service in Australia - among others. The Glock 23 is a .40 S&W version of the compact Glock 19. It is dimensionally identical to the Glock 19, but is slightly heavier and uses a modified slide, frame, .40 S&W barrel, and a standard magazine capacity of 13 rounds. The factory 15-round magazine from the larger Glock 22 will function in the Glock 23. The Glock 24 is a .40 S&W long-slide variant of the Glock 22, similar in concept to the Glock 17L. Additionally, a compensated, ported-barrel version designated the 24C was also produced. The Glock 24 was introduced in 1994 and officially dropped from the company's regular product lineup upon the release of the Glock 34 and 35.[80] The Glock 27 is a .40 S&W version of the subcompact Glock 26, with a standard magazine capacity of 9 rounds. The factory magazines from the larger Glock 22 and 23 will function in the Glock 27, increasing capacity to 13 or 15 rounds. Spacers are available that fit on these larger-capacity magazines themselves; they have the effect of "extending" the magazine well of the pistol, thereby improving the ergonomic feel of the pistol when the longer magazines are inserted. The Glock 35 is a .40 S&W version of the competition Glock 34. The Glock Model 35 is the current service pistol for the Kentucky State Police. As is typical of pistols chambered in .40 S&W, each of the standard Glock models (22, 23, and 27) may be easily converted to the corresponding .357 SIG chambering (Glock 31, 32, and 33, respectively) simply by replacing the barrel. No other parts need to be replaced, as the .40 S&W magazines will feed the .357 SIG rounds. 380 ACP The first two .380 ACP models are primarily intended for markets which prohibit civilian ownership of firearms chambered in military calibers such as 9×19mm Parabellum. Due to the relatively low bolt thrust of the .380 ACP cartridge, the locked-breech design of the Glock 19 and Glock 26 was minimally modified for the Glock 25 and Glock 28 to implement unlocked breech operation. It operates via straight blowback of the slide. This required modification of the locking surfaces on the barrel, as well as a redesign of the former locking block. Unusual for a blowback design, the barrel is not fixed to the frame. It moves rearward in recoil until it is tilted below the slide, similar to the standard locked-breech system. The reduced size and mass of the Glock 42 required return to the Glock-standard locked-breech design. The Glock 25, introduced in 1995, is a blowback derivative of the compact (102 mm (4.0 in) barrel) Glock 19. The magazine capacity is 15 rounds. Standard fixed sight elevation is 6.9 mm, unlike the 6.5 mm elevation used for the 9×19mm models. The Glock 28, introduced in 1997, is a blowback derivative of the subcompact (87 mm (3.4 in) barrel) Glock 26. The standard magazine capacity is 10 rounds, but the 15-round Glock 25 magazine will function in the Glock 28. Standard fixed-sight elevation is 6.9 mm, unlike the 6.5 mm elevation used for the 9×19mm Parabellum models. The Glock 42, introduced in 2014, is an all-new locked-breech "slimline" (83 mm (3.3 in) barrel) design. The single-stack magazine is unique to this model, with a capacity of six rounds. It is Glock's smallest model ever made and is manufactured in the USA, which unlike the Glock 25 and 28, allows domestic sales in that market. .357 SIG The subcompact Glock 33 in .357 SIG The Glock 31 is a .357 SIG variant of the full-sized Glock 22. The standard magazine capacity of the Glock 31 is 15 rounds. The Glock 32 is a .357 SIG variant of the compact Glock 23. The standard magazine capacity of the Glock 32 is 13 rounds. The Glock 33 is a .357 SIG variant of the subcompact Glock 27. The standard magazine capacity of the Glock 33 is 9 rounds. As is typical of pistols chambered in .357 SIG, each of the standard Glock models (31, 32, and 33) may be easily converted to the corresponding .40 S&W chambering (Glock 22, 23, and 27, respectively) simply by replacing the barrel. No other parts need to be replaced, as the .357 SIG magazines will feed the .40 S&W round. 45 GAP Glock pistols chambered for the .45 GAP (and the .45 ACP) feature octagonal polygonal rifling rather than the hexagonal shaped bores used for models in most other chamberings. Octagonal rifling provides a better gas seal in relatively large diameter rifled bores, since an octagon resembles a circle more closely than a hexagon. The Glock 37 is a .45 GAP version of the Glock 17. It uses a wider, beveled slide, larger barrel, and different magazine, but is otherwise similar to the Glock 17. The Glock 37 first appeared in 2003. It was designed to offer ballistic performance comparable with the .45 ACP in the frame size of the Glock 17. The concern with the size of the Glock 20/21 has been addressed by the Glock 36, 21SF, and 30SF, all of which featured reduced-size frames. The standard magazine capacity of the Glock 37 is 10 rounds. The Glock 38 is a .45 GAP version of the compact Glock 19. The standard magazine capacity of the Glock 38 is 8 rounds. The Glock 39 is a .45 GAP version of the subcompact Glock 26. The standard magazine capacity of the Glock 39 is 6 rounds.
