Likewise with .40 S&W Glock 22 magazines, which will fit and function in both Glock 23 and Glock 27 pistols. The connector ensures the pistol can only fire semiautomatically. They feature additional openings that allow liquids to flow and escape around them, offering enhanced reliability when water has penetrated into the firing pin assembly channel. They are positioned differently which is why barrels are not interchangeable between the full sized and compact frames. Several samples of the 9×19mm Glock 17 (so named because it was the 17th patent procured by the company[13]) were submitted for assessment trials in early 1982, and after passing all of the exhaustive endurance and abuse tests, the Glock emerged as the winner. 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. Generation 5 magazines will not interchange with any previous GLOCK generations. The Glock's frame, magazine body, and several other components are made from a high-strength nylon-based polymer invented by Gaston Glock, called Polymer 2. Replace the base plate on the Gen 5 magazines. [121], The Tatmadaw of Burma has adopted a clone of the Glock 17 known as the MA5 MK II. When using a Gen 5 magazine with the extended base plate, the front of the base plate hits the lip.. Updates centered on ergonomics and the recoil spring assembly. The grip has an angle of 109° and a nonslip, stippled surface on the sides and both the front and rear straps. According to Major Riddle with the IMPD; "Glock is working to correct the problem and we hope to begin issuing the new [17Ms] as soon as December".[45][46]. But a subcompact magazine for the 26 won’t work in the 17 because it’s too small. These magazines are also notched on the right side for the magazine release. [6] Glocks are also popular firearms among civilians for recreational and competition shooting, home- and self-defense, and concealed or open carry. Any Glock Gurus out there know what parts aren't compatible? In 1991, an integrated recoil spring assembly replaced the original two-piece recoil spring and tube design. Each GLOCK delivers on our promise of safety, reliability, and simplicity at an affordable price. The redesigned magazine floor plates feature a frontward protruding lip to offer grip for manual assisted extraction and the magazine follower became orange colored for easier visual identification. Turkish company Akdal Arms produces a pistol named the Ghost TR01, which is heavily influenced by Glock pistols in its design.[116]. These early Glock 17 "pencil barrel" pistols are considered rare and highly desirable by Glock collectors. [5], Despite initial resistance from the market to accept a perceived "plastic gun" due to concerns regarding durability and reliability which proved unfounded,[citation needed] as well as fears that its use of a polymer frame might bypass the detection of the metal detectors in airports, also unfounded,[citation needed] Glock pistols have become the company's most profitable line of products as well as supplying national armed forces, security agencies, and police forces in at least 48 countries. As of January 2009, the Glock 20, 21, 29, and 30 were offered in short-framed variations. [27] These early Glock (Gen 1) pistols (serial number prefix AF through AM) were also manufactured with a barrel that had a smaller overall diameter and thinner bore walls, later known as "pencil barrels." Nothing is changed internally or really … The initial production run is limited to 10,000 units. The Tenifer treatment is applied in a 500 °C (932 °F) nitrate bath. The "Gen 5" slide can feature front serrations (FS) to provide an additional tactile traction surface choice. Polymer 2 is resistant to shock, caustic liquids, and temperature extremes where traditional steel/alloy frames would warp and become brittle. With Glock Gen 5 magazines, the extended base plate will not fit the Glock 19X. We carry a diverse selection from high capacity to standard per model. Zebra Active Member. The factory-standard firing pin spring is rated at 24 N (5.4 lbf), but by using a modified firing pin spring, it can be increased to 28 N (6.3 lbf) or to 31 N (7.0 lbf). Yes all glock magazines that are the same caliber are interchangeable, unless you try to put in a smaller mag, like a 26 mag into a 17 or a 19 How do you think about the answers? It is pushed upward to release the firing pin for firing only when the trigger is actuated and the safety is pushed up through the backward movement of the trigger bar. Glock has updated its basic design several times throughout its production history. The reduced size and mass of the Glock 42 required return to the Glock-standard locked-breech design. For the engineer Gaston Glock, see, *Semi-automatic pistol *Machine pistol (Glock 18), Glock 17 "first-generation" full-size model adopted in 1985 by the Norwegian military under the P80 designation, Glock 34 with a GTL 22 attachment featuring a dimmable xenon white light and a red laser, A military diver displaying a Glock 17 fitted with maritime spring cups (not visible in picture, these are part of the internal mechanism), 2011 recoil spring assembly exchange program, Commemorative, anniversary, engraved, and other rare Glocks. [29], The polymer frames of third-generation models can be black, flat dark earth, or olive drab. 188 81. [62] Glock steel parts using the Tenifer treatment are more corrosion resistant than analogous gun parts having other finishes or treatments, including Teflon, bluing, hard chrome plating, or phosphates. The first 4th Generation (Gen 4) Glocks came along in 2009. So a full-size Glock 17 magazine (9mm) will work in smaller Glocks like the 19 and the 26. In late 1983, the United States Department of Defense inquired about the Glock pistol and received four samples of the Glock 17 for unofficial evaluation. Magazine Release Button. Gen4 magazines will work in older models. 5,453 Posts #2 • Jan 28, 2011. [122] They're currently being manufactured and adopted for Myanmar's special forces units. Double Stacked and Staggered for Maximum Capacity. Website by Hudson. The magazines are made of steel and are overmolded with plastic. This design gives the recoil spring fewer tasks as the action cycles, helping to ensure that sufficient energy is available to strip a new round from the magazine and achieve full battery even when the breech, chamber, and/or magazine are heavily fouled. No, not all GLOCK magazines are interchangeable. The Austrian government would not allow Glock to recreate the Austrian Army Proof designations on the slide, barrel, or frame. 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. G19 compact size slide is interchangeable with G47 standard size slide. Where the Glock Generation 4 handgun has the magazine release on the left side, either Generation of Magazine is going to work in the Generation 4 assembly. Glock Magazines. Thumb rests on both sides of the frame and finger grooves on the front strap were added. [64], The newer lines of Glock pistols - i.e. The three safety mechanisms are automatically disengaged one after the other when the trigger is squeezed, and are automatically reactivated when the trigger is released.[17][68]. Many internal parts were less conspicuously revised. [69] For jurisdictions which restrict magazine capacity to 10 rounds, Glock offers single-stack, 10-round magazines. [60] The frame houses the locking block, which is an investment casting that engages a 45° camming surface on the barrel's lower camming lug. Please note: we no longer accept orders over the phone. Glock's entry featured an optional ambidextrous magazine release and MIL-STD-1913 rail along with a reduction in the size of the backstrap. [67] The external safety is a small inner lever contained in the trigger. [41], On 29 June 2016 the United States Federal Bureau of Investigation (FBI) awarded a contract to Glock to provide new 9×19mm Parabellum chambered duty pistols. The earliest Glock boxes had ammunition storage compartments that allowed for 17 rounds of 9mm to be stored with the pistol. The first Glock 17s imported to the US were serialized with an alpha-numeric (two letter prefix followed by three numbers) stamped into the slide, barrel, and a small metal plate inserted into the bottom side of the polymer frame. They have come in basically 5 generations, and this is a breakdown of the relevant differences. [22] The British preferred the Glock 17 Gen 4 over the Beretta Px4 Storm, FN FNP, Heckler & Koch P30, SIG Sauer P226, Smith & Wesson M&P, and Steyr M9A1 of which 19 pistols each, all chambered in 9×19mm Parabellum, where trailed in the R9GSP trails. This camming action terminates the barrel's movement while the slide continues back under recoil, extracting and ejecting the spent cartridge casing. 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. The introduction of fourth-generation Glock pistols continued in July 2010 when the Glock 19 and Glock 23, the reduced size "compact" versions of the Glock 17 and Glock 22, became available for retail. [120] It is not known if they could make their way to Iranian Military and replace the Browning Hi-Power, 1911 and SIG P226 pistols and they were possibly some prototypes and have never gone on mass production. A punch is provided to remove the standard trigger housing pin and replace it with the longer cross pin needed to mount the medium or large backstrap that will increase the trigger distance by 2 mm (0.079 in) or 4 mm (0.16 in). G47 standard size slide is interchangeable with G19 compact size slide. A recent study by Stephen Christen and Hans Rudolf Jordi, and published by Forensic Science International in February 2019, shows that the new GMB barrels leave more identifiably unique markings on the fired projectile. [64], Aside from the original Austrian company, Glock pistols are manufactured by the Glock Inc. subsidiary division located in the United States. [123], In 2017, it's reported that Norinco is able to make a clone of the Glock 17[124] known as the NP-7 (or NP7). Additionally, many law enforcement agencies had the department name, logo, or badges engraved on the slides of issued duty weapons. As you know, Glock gen 5 plastic frames don't have the finger grips anymore. A dual recoil spring was added for better shooting as well. [125] The pistol is subcontracted to Hunan Ordnance Small Arms Research Institute Co, Ltd.[126][127] Its features appear to be influenced by the fourth gen version of the Glock 17. Current 10mm and .45 ACP Glock magazines are manufactured with ambidextrous magazine release cutouts. A spring-loaded sheet-metal pressing serves as the slide catch, which is secured from unintentional manipulation by a raised guard molded into the frame. [5] Within three months, Glock developed a working prototype that combined proven mechanisms and traits from previous pistol designs. These magazines are notched on the right side for the magazine release. [59] This plastic was specially formulated to provide increased durability and is more resilient than carbon steel and most steel alloys. 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. 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.[72][73][74]. Well since then the Gen 3 and Gen 4 Glock’s have come out and it’s time for a historical reflection of the Engineering differences between the 4 (Four) generations of Glock’s to prevent the continuation of them being spoken of as “Cosmetic” changes. [28], A mid-life upgrade to the Glock pistols involved the addition of checkering on the front strap and trigger guard and checkering and serrations to the back strap. [34], Mechanically, fourth-generation Glock pistols are fitted with a dual recoil spring assembly to help reduce perceived recoil and increase service life expectancy. This trigger modification is available in two versions: NY1 and NY2 that are rated at 25 N (5.6 lbf) to 40 N (9.0 lbf) and 32 N (7.2 lbf) to 50 N (11.2 lbf), respectively, which require about 20 N (4.5 lbf) to 30 N (6.7 lbf) of force to disengage the safeties and another 10 N (2.2 lbf) to 20 N (4.5 lbf) in the second stage to fire a shot. The hammer-forged barrel has a female type polygonal rifling with a right-hand twist. Besides that, non-firing dummy pistols ("P" models) and non-firing dummy pistols with resetting triggers ("R" models) have a bright red frame and Simunition-adapted practice pistols ("T" models) – a bright blue frame for easy identification.[30]. The first two .380 ACP models are primarily intended for markets that prohibit civilian ownership of firearms chambered in military calibers such as 9×19mm Parabellum. Free shipping and returns on The Glock 17 and the Glock 19 are, essentially, the same gun, except that the Glock 19 has a slightly smaller barrel and grip. Glock had extensive experience in advanced synthetic polymers, which was instrumental in the company's design of the first commercially successful line of pistols with a polymer frame. There are three sidearms made by Iranian DIO's Shahid Kaveh Industry Complex which they call Ra'ad (has a safety selector, possibly an unlicensed copy of Glock 17), Glock 19 and Kaveh-17 (probably an improved Ra'ad, a variant of Glock 17S), which all of them are unlicensed clones of Glock pistols. For these and other reasons, Glock pistols are commonly considered to be some of the most reliable striker-fired, semi-automatic handguns available, with some independent testing even showing a Glock taking a lead over a Sig Sauer P320[55] in a wet/dry reliability test, even though the latter was selected as the winner of the U.S. Army's MHS competition. The initial two fourth-generation models announced were the full-sized Glock 17 and Glock 22, chambered for the 9×19 mm Luger and .40 S&W cartridges, respectively. A completely standard GLOCK will be sufficient for most shooters, but you might want to go beyond the average shooter. The 43x and the 48 have longer grips that allow for a full three-finger hold and a 10-round capacity. It is believed that Glock designed and created this adjustable rear sight over a weekend in order to meet the ATF's importation requirements, and so it was dubbed the "weekend" sight. The stabilization of the round is not by conventional rifling, using lands and grooves, but rather through a polygonal profile consisting of a series of six or eight interconnected noncircular segments (only the .45 ACP and .45 GAP have octagonal polygonal rifling). And if so, can a newer gen 5 Glock slide be put onto a, say gen 4 Glock lower frame? [54] By relying partially on force from the shooter's trigger finger to cock the striker, a Glock effectively reduces the load on the recoil spring as the slide moves forward into battery, whereas almost all other striker-fired pistols on the market rely fully on the recoil spring to cock the striker.
