Glock

Glock GmbH (trademarked as GLOCK) is a weapons manufacturer of handguns that are trade marked as "Safe Action Pistols." Glock is headquartered in Deutsch-Wagram, Austria. Named after its founder, Gaston Glock, Glock is best known for its line of polymer-framed pistols; it also produces equipment such as field knives and entrenching tools.

The Glock handguns are in use by a majority of US and international law enforcement agencies and military personnel. Glock handguns are also very popular with civilians, especially for personal protection and practical shooting. Glock currently produces 35 models of handguns. The US-led Multi National Force-Iraq has equipped the Iraqi military and the Iraqi National Police with Glock sidearms.

History

Founded in 1963, Glock started out as a manufacturer of curtain rods before branching out into the arms industry in the 1970s, manufacturing machine gun belts, practice hand grenades, plastic magazines, field knives, and entrenching tools for the Austrian Army. When, in the early 1980s, the Austrian Army requested a pistol model, Glock responded with the Glock 17, a 9 mm semi-automatic pistol. (The 17 was so-named because it was Gaston Glock's seventeenth patent.) The Austrian Army adopted the Glock 17 in 1982 with the Norwegian Army adopting the model two years later. One year later, Glock Inc. was established in the US in Smyrna, Georgia. In the next few years, Glock expanded its 9 mm product line, developing the select-fire Glock 18 in 1986 and the Glock 17L and Glock 19 in 1988. In 1990 Glock became the first manufacturer to offer models chambered for the .40 S&W cartridge, the Glock 22 and the Glock 23, beating Smith & Wesson to the marketplace with pistols for their own cartridge.

Glock sidearms are common handguns among law enforcement agencies and military organizations around the world. The popularity of Glock pistols can be attributed to a number of factors. They are said to be very reliable, being able to function under extreme conditions and to fire a wide range of ammunition types. The simplicity of the Glock design contributes to this reliability, as it contains a relatively small number of components (nearly half as many as the typical handgun) making maintenance and repair easy. Disassembly for the Glock pistol is simple, making it easy to field strip without expensive tools.

The polymer frame makes them lighter than typical steel or aluminum-framed handguns, which is attractive for police officers and civilians who carry firearms for extended periods of time. Glock pistols do not have any external controls such as levers, decockers, or manual safeties (stock). This adds to the simplicity of use and removes a potential source of errors when operating the handgun under stress. Most of the steel components in a Glock pistol are treated with a nitriding process called "Tenifer", which increases the surface hardness and makes the weapon resistant to corrosion and wear.

The popularity of Glock pistols seems to have inspired other manufacturers to begin production of similar polymer-framed firearms, including the Springfield XD, Steyr MA1, Smith & Wesson M&P, and Walther P99 pistols. Glocks tend to be in the middle of the price range for quality pistols: generally less expensive than similar SIG-Sauer and HK USP pistol models, but more expensive than Hi-Point or Taurus models.

"Plastic pistol" myths

Glock pistols do set off metal detectors and can indeed be detected by X-ray machines, due to their metal barrels, slides, magazines, and ammunition. The erroneous claim that they could not was first made in an article by columnist Jack Anderson, entitled, "Quaddafi Buying Austrian Plastic Pistol", published in The Washington Post on January 13, 1985. The claim was then reported by the Associated Press and further reported by many United States television news stations and newspapers. It has since become an urban legend that to this day continues to appear in news reports and movies, and has even been a topic of debate in the United States Congress and during oral argument before the United States Supreme Court in the case of District of Columbia v. Heller.

In fact, 83.7% (by weight) of the Glock pistol is normal ordnance steel and the "plastic" parts are a dense polymer known as "Polymer 2", which is radio-opaque and is therefore visible to X-ray security equipment. In addition, virtually all of these "plastic" parts contain embedded steel not to make the firearms "detectable", but to increase functionality and shooting accuracy. Contrary to popular movies like Die Hard 2: Die Harder, neither Glock nor any other gun maker has ever produced a "porcelain", "ceramic" or "plastic" firearm which is undetectable by ordinary security screening devices. Even if a pistol were completely undetectable by either X-ray machines or metal detectors were to be developed, the ammunition inside would still be detectable.

In Die Hard 2, the character John McClane portrayed by Bruce Willis specifically referred to a non-existent "Glock 7" with many fictitious characteristics:

That punk pulled a Glock 7 on me! You know what that is? It's a porcelain gun made in Germany. It doesn't show up on your airport X-ray machines, and it costs more than you make here in a month!

Mike Papac, an armorer at Cinema Weaponry, which supplied the Glock pistols used in Die Hard 2, has stated, "I remember when we did that scene, I tried to talk them out of it. There's no such thing as a gun invisible to metal detectors, and there shouldn't be, but they wouldn't budge. They had it written into the script and that was that."

The Glock pistol design was not the first to incorporate a plastic frame. Heckler & Koch used polymer for their VP70 pistol frame in 1970[4]. HK's innovation of polymer frames and polygonal rifling seem to have been influential in the Glock design. Still earlier, Remington introduced their polymer-framed Nylon 66 Rifle in 1959. This was so revolutionary at the time that Remington dyed the plastic brown to resemble wood and fitted a cosmetic sheet-metal cover on the receiver to make it appear to be made from steel. Further, the most extensive use of polymers in a pistol was in the Ram-Line Syn Tech Exactor pistol with a barrel made from steel-lined plastic.

Explosive malfunctions

The explosive malfunction of a firearm, dubbed a kB! (or kaBoom!) by firearms magazine writer Dean Speir, generally results from case failure in a cartridge. Explosive malfunctions in Glock pistols usually damage the firearm and can cause injury to the shooter.

Controversy arose over Glock's safety standards when in 2001 several instances of explosive malfunction occurred in Glock pistols sold to police departments in the United States. Upon pulling the trigger, the cartridge case would rupture and cause an explosion that would tear apart the gun and sometimes send fragments into the shooter's face.

The cause of this malfunction is unknown but may be due to issues with a purposely oversized (loose), and partially unsupported chamber in Glock's pistols chambered in .40 S&W, .45 ACP, and 10 mm Auto. The chamber lacks full support in the rear by the feed ramp in order to facilitate feed reliability. The lack of support in the chamber, usually combined with the use of lead (unjacketed) bullets, reloaded ammunition, or poor-quality factory ammunition (all in violation of Glock's recommendations), would cause the case to fail. The subsequent rapid expansion of gas into the chamber caused the cartridge casing to expand beyond normal specifications near the feed ramp at which time the casing would rupture, sometimes damaging the polymer frame and usually ejecting the magazine downwards out of the pistol grip.

Glock, in its own defense, says that the manual that accompanies each pistol informs the shooter of the dangers of using non-factory rated ammunition, and that the firearm will function safely if the shooter uses factory-loaded, jacketed ammunition and properly cleans and cares for the firearm. Supporters also point out that this type of malfunction occurs in other firearms as well. However, there continues to be controversy over the presence of an unsupported chamber, critics arguing that it is not necessary and is a liability for the company.

It has been stated (by Glock and at least one noted barrel maker, the late Gale MacMillan) that because of the specific design of the polygonal rifling in the Glock pistol, operators should not shoot non-jacketed lead ammunition. Lead residue can quickly build up, decreasing the bore diameter and create a dangerous over-pressurization in the barrel, leading to structural failure or warping in the chamber of the barrel. One can notice a bulge in the fired case ejected from the pistol (even with target loads) to see the result of the unsupported chamber.

Knives

Glock currently manufactures two models of knives. The Field Knife 78 is a classic knife, with a 6.5 inch (165 mm) blade and 11.4 inch (290 mm) overall length. The Survival Knife 81 has the same overall dimensions with an additional saw on the back of the blade. Both knives are phosphate-treated and have a Glock-polymer sheath and are available in olive, tan, and black.

How the Glock works.

Colt .45 Model 1911 and some variants

M1911 pistol

Mid-1945 produced M1911A1 U.S. Army semi-automatic pistol by Remington Rand. This one was re-built by Anniston Army Depot, October 1972, and carries the ANAD 1072 stamp. The cartridges shown are the .45 ACP (left) and 7.65 mm Browning/.32 ACP (right). Confiscated early 2004 in or around Al-Qurna, Iraq, by Dancon/Irak. Destroyed shortly after.

The M1911 is a single-action, semi-automatic pistol (handgun) chambered for the .45 ACP cartridge. It was designed by John M. Browning, and was the standard-issue side arm for the United States armed forces from 1911 to 1985, and is still carried by some U.S. forces. It was widely used in World War I, World War II, the Korean War and the Vietnam War. Its formal designation as of 1940 was Automatic Pistol, Caliber .45, M1911 for the original Model of 1911 or Automatic Pistol, Caliber .45, M1911A1 for the M1911A1, adopted in 1924. The designation changed to Pistol, Caliber .45, Automatic, M1911A1 in the Vietnam era. In total, the United States procured around 2.7 million M1911 and M1911A1 pistols during its service life.

Comparison of government-issue M1911 and M1911A1 pistols

The M1911 is the most well-known of John Browning's designs to use the short recoil principle in its basic design. Besides the pistol being widely copied itself, this operating system rose to become the pre-eminent type of the 20th century and of nearly all modern centerfire pistols.

History

General William Crozier became Chief of Ordnance of the Army in 1901.

Early history and adoption

The M1911 pistol originated in the late 1890s, as a search for a suitable self-loading (or semi-automatic) handgun, to replace the variety of revolvers then in service. The United States of America was adopting new firearms at a phenomenal rate; several new handguns and two all-new service rifles (the M1892/96/98 Krag and M1895 Navy Lee), as well as a series of revolvers by Colt and Smith & Wesson for the Army and Navy were adopted just in that decade. The next decade would see a similar pace, including the adoption of several more revolvers and an intensive search for a self-loading pistol that would culminate in official adoption of the M1911 after the turn of the decade.

Hiram S. Maxim had designed a self-loading pistol in the 1880s, but was preoccupied with machine guns. Nevertheless, the application of his principle of using bullet energy to reload led to several self-loading pistols in the 1890s. The designs caught the attention of various militaries, each of which began programs to find a suitable one for their forces. In the U.S., such a program would lead to a formal test at the turn of the 19th to the 20th century.

During the end of 1899 and start of 1900, a test of self-loading pistols was conducted, which included entries from Mauser (the C96 "Broomhandle"), Mannlicher (the Steyr Mannlicher M1894), and Colt (the Colt M1900).

This led to a purchase of 1,000 DWM Luger pistols, chambered in 7.65 mm Luger, a bottlenecked cartridge. These would go on field trials but ran into some issues, especially in regard to stopping power. Other governments had also made similar complaints, which resulted in DWM producing an enlarged version of the round, the 9mm Parabellum (known in current military parlance as the 9x19mm NATO), a necked-up version of the 7.65 mm round. Fifty of these were tested as well by the U.S. Army in 1903.

In response to problems encountered by American units fighting Moro guerrillas during the Philippine-American War, the then-standard .38 Long Colt revolver was found to be unsuitable for the rigors of jungle warfare, particularly in terms of stopping power, as the Moros had very high battle morale and frequently used drugs to inhibit the sensation of pain.[citation needed] The U.S. Army briefly reverted to using the M1873 single-action revolver in .45 Colt caliber, which had been standard during the last decades of the 19th century; the slower, heavier bullet was found to be more effective against charging tribesmen. The problems with the .38 Long Colt led to the Army shipping new single action .45 Colt revolvers to the Philippines in 1902. It also prompted the then-Chief of Ordnance, General William Crozier, to authorize further testing for a new service pistol.

Following the 1904 Thompson-LaGarde pistol round effectiveness tests, Colonel John T. Thompson stated that the new pistol "should not be of less than .45 caliber" and would preferably be semi-automatic in operation. This led to the 1906 trials of pistols from six firearms manufacturing companies (namely, Colt, Bergmann, Deutsche Waffen und Munitionsfabriken (DWM), Savage Arms Company, Knoble, Webley, and White-Merril).

Of the six designs submitted, three were eliminated early on, leaving only the Savage, Colt, and DWM designs chambered in the new .45ACP (Automatic Colt Pistol) cartridge. These three still had issues that needed correction, but only Colt and Savage resubmitted their designs. There is some debate over the reasons for DWM's withdrawal — some say they felt there was bias and that the DWM design was being used primarily as a "whipping boy" for the Savage and Colt pistols, though this does not fit well with the earlier 1900 purchase of the DWM design over the Colt and Steyr entries. In any case, a series of field tests from 1907 to 1911 were held to decide between the Savage and Colt designs. Both designs were improved between each testing over their initial entries, leading up to the final test before adoption.

Among the areas of success for the Colt was a 6,000 round test at the end of 1910 attended by its designer, John Browning. The Colt gun passed with flying colors, having no malfunctions, while the Savage designs had 37.

Service history

Following its success in trials, the Colt pistol was formally adopted by the Army on March 29, 1911, thus gaining its designation, M1911 (Model of 1911). It was adopted by the Navy and Marine Corps in 1913. Originally manufactured only by Colt, demand for the firearm in World War I saw the expansion of manufacture to the government-owned Springfield Armory.

Battlefield experience in the First World War led to some more small external changes, completed in 1924. The new version received a modified type classification, M1911A1. Changes to the original design were minor and consisted of a shorter trigger, cutouts in the frame behind the trigger, a curved mainspring housing, a longer grip safety spur (to prevent hammer bite), a wider front sight, a shorter spur on the hammer, and simplified grip checkering. Those unfamiliar with the design are often unable to tell the difference between the two versions at a glance. No internal changes were made, and parts remained interchangeable between the two.

World War II

World War II and the years leading up to it created a great demand. During the war, about 1.9 million units were procured by the U.S. Government for all forces, production being undertaken by several manufacturers, including Remington Rand (900,000 produced), Colt (400,000), Ithaca Gun Company (400,000), Union Switch & Signal (50,000), Singer (500), the Springfield Armory and Rock Island Arsenal. So many were produced that, after 1945, the government did not order any new pistols, and simply used existing parts inventories to "arsenal refinish" guns when necessary. This pistol was favored by US military personnel.

M1911A1

Before World War II, a small number of Colts were produced under license at the Norwegian weapon factory Kongsberg Vaapenfabrikk (these Colts were known as "Kongsberg Colt"). During the German occupation of Norway the production continued. These pistols are highly regarded by modern collectors. German forces used captured M1911A1 pistols, using the designation "Pistole 660(a)". The 1911 pattern also formed the basis for the Argentine Ballester-Molina and certain Spanish Star and Llama pistols made after 1922.

Replacement for most uses

After World War II, the M1911 continued to be a mainstay of the United States Armed Forces in the Korean War and the Vietnam War and was even used during Desert Storm in some U.S. Army units.

However, by the late 1970s the M1911A1 was acknowledged to be showing its age. Under political pressure from NATO to conform to the NATO-standard pistol cartridge, the US Air Force's Joint Service Small Arms Program was run to select a new semi-automatic pistol using the NATO-standard 9mm Parabellum pistol cartridge (a cartridge that had been previously tested by the US Army in 1903 and found wanting). After trials, the Beretta 92S-1 was chosen. This result was contested by the Army which subsequently ran its own competition (the XM9 trials) in 1981 which eventually lead to the official adoption of the Beretta 92F on January 14, 1985. By the later 1980s production was ramping up despite a controversial XM9 retrial and a separate XM10 reconfirmation, which was boycotted by some entrants of the original trials, cracks in the frames of the Beretta-produced pistols, and also despite a dangerous problem with slide separation that resulted in injuries to some US Navy service members. This last resulted in it being updated to the 92FS standard, which includes additional protection for the user.

By the early 1990s, most M1911A1s had been replaced by the M9, though a limited number remain in use by special units. The United States Marine Corps in particular were noted for continuing the use of M1911 pistols for selected personnel in MEU(SOC) and reconnaissance units (though the USMC also purchased over 50,000 M9 handguns). For its part, the United States Special Operations Command (USSOCOM) issued a requirement for a .45 ACP handgun (Offensive Handgun Weapon System (OHWS) trials). This resulted in the Heckler & Koch OHWS becoming the MK23 Mod 0 Offensive Handgun Weapon System (beating a Colt OHWS, a much modified 1911). Dissatisfaction with the Beretta M9's stopping power has actually promoted re-adoption of the 1911 (along with other handguns) among USSOCOM units in recent years, though the M9 remains predominant both within SOCOM and in the US military in general.

Current users

The M1911A1 design is favored by a large number of police SWAT teams throughout the United States. Many military and law enforcement organizations in the United States and many other countries continue to use (often modified) M1911A1 pistols because they favor the greater stopping power of the .45 cartridge and the superior shootability of the weapon.[citation needed] Marine Force Recon, Los Angeles Police Department Special Weapons and Tactics, the FBI Hostage Rescue Team and 1st Special Forces Operational Detachment - Delta (Delta Force) are among them. The Tacoma, WA Police Department made history in 2001 by becoming the first metropolitan police department in nearly 50 years to adopt the 1911 as its official carry weapon. The Tacoma Police Department selected the Kimber Pro Carry II or Pro Carry II HD as optional, department supplied weapons available to its officers.

The M1911A1 is also extremely popular among the general public in the United States for practical and recreational purposes. The pistol is commonly used for concealed carry (thanks in part to a single-stack magazine, which makes for a thinner pistol; thus easier to conceal), personal defense, target shooting, and competition. Numerous aftermarket accessories allow users to customize the pistol to their liking. There are a growing number of manufacturers of 1911-type pistols and the model continues to be quite popular for its reliability, simplicity, and patriotic appeal. Various tactical, target, and compact models are available. Price ranges from a low end of $250 for an imported model to more than $3,000 for the best competition or tactical models such as those by Smith and Wesson, Rock River Arms, Springfield Armory, STI International Inc, Strayer Voigt Inc, Kimber Manufacturing, Wilson Combat, and Les Baer.

Due to an increased demand for M1911 pistols among Army Spec Ops units, who are known to field a variety of 1911 pistols, the Army Marksmanship Unit began looking to develop a new generation of M1911s and launched the M1911-A2 project in late 2004. The goal was to produce a minimum of seven variants with various sights, internal and external extractors, flat and arched mainspring housings, integral and add-on magazine wells, a variety of finishes and other options, with the idea of providing the end-user a selection from which to select the features that best fit their missions. The AMU performed a well received demonstration of the first group of pistols to the Marine Corps at Quantico and various Spec Ops units and Ft. Bragg and other locations. The project provided a feasibility study with insight into future projects. Models were loaned to various Spec Ops units, the results of which are classified. An RFP was issued for a Joint Combat Pistol but it was ultimately canceled. Currently units are experimenting with a 1911 platform in .40 which will incorporate lessons learned from the 1911 A2 project. Ultimately, the 1911 A2 project provided a test bed for improving existing 1911s. Perhaps we will see development of an improved 1911 variant in the near future.

Marine Expeditionary Units formerly issued M1911s to Force Recon units.[citation needed] Hand-selected Colt M1911A1 frames were gutted, deburred, and prepared for additional use by the USMC Precision Weapon Section (PWS) at Marine Corps Base Quantico. They were then assembled with after-market grip safeties, ambidextrous thumb safeties, triggers, improved high-visibility sights, accurized barrels, grips, and improved Wilson magazines. These hand-made pistols were tuned to specifications and preferences of end users.

In the late 1980s, Marine Corps Colonel Robert Young laid out a series of specifications and improvements to make Browning's design ready for 21st century combat, many of which have been included in MEU(SOC) pistol designs. However, as the U.S. Marine Corps began its process of hand selecting members from its Force Recon to be submitted to USSOCOM as Marine Corps Special Operations Command, Detachment One (MCSOCOM Det-1), the selection of a .45 ACP M1911A1-based pistol meant roughly 150 units would be needed, quickly. The PWS was already backlogged with producing DMRs, USMC SAM-Rs, and updating M40A1s to M40A3s, so Det-1 began the search for COTS (commercial off-the-shelf) surrogates to use. Discovering that the Los Angeles Police Department was pleased with their special Kimber M1911 pistols, a single source request was issued to Kimber for just such a pistol despite the imminent release of their TLE/RLII models. Kimber shortly began producing a limited number of what would be later termed the Interim Close Quarters Battle pistol (ICQB). Maintaining the simple recoil assembly, 5-inch barrel (though using a stainless steel match grade barrel), and internal extractor, the ICQB is not much different from Browning's original design.

The final units as issued to MCSOCOM Det-1 are the Kimber ICQBs with Surefire IMPL (Integrated Military Pistol Light), Dawson Precision Rails, Tritium Novak LoMount sights, Gemtech TRL Tactical Retention Lanyards, modified Safariland 6004 holsters, and Wilson Combat '47D' 8 round magazines. They have reportedly been used with over 15,000 rounds apiece.

Numbers of Colt 1911s were used by the Royal Navy as sidearms during World War I in .455 Webley Automatic caliber. The handguns were then transferred to the Royal Air Force where they saw use in limited numbers up until the end of World War II as sidearms for air crew in event of bailing out in enemy territory. Some units of the South Korean Air Force still use these original batches as officers' sidearms(2008).

Design

Asking for a .45-caliber automatic pistol was a tall order that few manufacturers or inventors attempted successfully in the early 20th century. To accomplish this, Browning settled on a design that is so timeless, it has been changed little in nearly 100 years of production. The basic principle of the pistol is recoil operation. As the expanding combustion gases force the bullet down the barrel, they give reverse momentum to the slide and barrel which are locked together during this portion of the firing cycle. After the bullet has left the barrel, the slide and barrel continue rearward a short distance.

At this point, a link pivots the barrel down, out of locking recesses in the slide, and brings the barrel to a stop. As the slide continues rearward, a claw extractor pulls the spent casing from the firing chamber and an ejector strikes the rear of the case pivoting it out and away from the pistol. The slide stops and is then propelled forward by a spring to strip a fresh cartridge from the magazine and feed it into the firing chamber. At the forward end of its travel, the slide locks into the barrel and is ready to fire again.

The military mandated a grip safety and a manual safety. A grip safety, sear disconnect, slide stop, half cock position, and manual safety (located on the left rear of the frame) are on all standard M1911A1s. Several companies have developed a firing pin block safety. Colt's 80 series uses a trigger operated one and several other manufacturers use a Swartz firing-pin safety, which is operated by the grip safety.



The same basic design has also been offered commercially and has been used by other militaries. In addition to the .45 ACP (Automatic Colt Pistol), models chambered for .38 Super, 9mm Parabellum, .400 Corbon, and other cartridges were also offered. The M1911 was developed from earlier Colt designs firing rounds such as .38 ACP. The design beat out many other contenders during the government's selection period, during the late 1890s and 1900s, up to the pistol's adoption. The M1911 officially replaced a range of revolvers and pistols across branches of the U.S. armed forces, though a number of other designs would see some use in certain niches.



Despite being challenged by newer and lighter weight pistol designs in .45 caliber, such as the Glock 21, the SIG Sauer P220 and the Heckler & Koch Mk 23, the 1911 shows no signs of decreasing popularity, and continues to be widely present in various competitive matches, such as those of IDPA and IPSC.



Also, despite its relatively large size, the M1911 has a very flat profile owing to its single-stack magazine design, easing concealment.

Memory groove grip safety

Safeties: A grip safety, sear disconnect, slide stop, a half cock position, and manual safety (located on the left rear of the frame) are on all standard M1911(A1)s. Several companies have developed a firing pin block. Colt's 80 series uses a trigger operated one and several other manufacturers (such as Smith & Wesson) use one operated by the grip safety.

Grip safety deactivation: A problem for some shooters is that they have trouble deactivating the grip safety when they hold the gun. This primarily affects shooters who have small hands. It can also occur when a shooter places his thumb on top of the thumb safety, which tends to reduce pressure on the grip safety. To rectify this problem, a number of grip safety manufacturers have designed safeties with extended ridges, so that when a shooter grips the gun, his hand will come into contact with the ridges and deactivate the safety (i.e., allowing the gun to fire). Some instructors find this "problem" to be a result of poor hand placement, since an 11 year-old was documented able to do so, or worn safety components, known to both military and civilian armourers and systematic checks are to be made to verify its functionality.
