The Colt 1911 handgun is one of the most famous gun designs in history. It is produced in several different models, each tailored for a different group of users (military, law enforcement, security, private etc.), and periodic changes have been made to update and improve it. Despite changes, the 1911 remains one of the most respected handgun designs ever made, and its future remains bright.
Among the areas of success for the Colt was a test at the end of 1910 attended by its designer, John Browning. 6,000 rounds were fired from a single pistol over the course of two days. When the gun began to grow hot, it was simply immersed in water to cool it. The Colt gun passed with no reported malfunctions, while the Savage designs had 37.
Service History
- 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, an arched mainspring housing, a longer grip safety spur (to prevent slide bite), a wider front sight, a shorter spur on the hammer, and simplified grip checkering by eliminating the "Double Diamond" reliefs. Those unfamiliar with the design are often unable to tell the difference between the two versions at a glance. No significant internal changes were made, and parts remained interchangeable between the two.
- Working for the U.S. Ordnance Office, David Marshall Williams developed a .22 training version of the M1911 using a floating chamber to give the .22 long rifle rimfire recoil similar to the .45 version. As the Colt Service Ace, this was available both as a handgun and as a conversion kit for .45 M1911 pistols.
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), and Singer (500). 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.
- 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, with the 920 examples stamped with Nazi Waffenamt codes being the most sought after. German forces also used captured M1911A1 pistols, using the designation "Pistole 660(a)". The M1911 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. It was also used during Desert Storm in specialized U.S. Army units and US Navy Mobile Construction Battalions (Seabees), and has seen service in both Operation Iraqi Freedom and Operation Enduring Freedom, with U.S. Army Special Forces Groups and Marine Corps Force Reconnaissance Companies.
- 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 ran a Joint Service Small Arms Program to select a new semi-automatic pistol using the NATO-standard 9mm Parabellum pistol cartridge. After trials, the Beretta 92S-1 was chosen. The Army contested this result and subsequently ran its own competition in 1981, the XM9 trials, eventually leading 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 that was boycotted by some entrants of the original trials, cracks in the frames of some pre-M9 Beretta-produced pistols, and also despite a problem with slide separation using higher than specified pressure rounds that resulted in injuries to some US Navy special operations operatives. This last issue resulted in an updated model that includes additional protection for the user, the 92FS, and updates to the ammunition used.
- 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 in the Offensive Handgun Weapon System (OHWS) trials. This resulted in the Heckler & Koch OHWS becoming the MK23 Mod 0 Offensive Handgun Weapon System, beating the Colt OHWS, a much modified M1911. Dissatisfaction with the stopping power of the 9mm Parabellum cartridge used in the Beretta M9 has actually promoted re-adoption of handguns based on the .45 ACP cartridge such as the M1911 design, 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
- Many military and law enforcement organizations in the United States and other countries continue to use (often modified) M1911A1 pistols including Marine Force Recon, Los Angeles Police Department S.W.A.T. and L.A.P.D. S.I.S., the FBI Hostage Rescue Team, F.B.I. regional S.W.A.T. teams, and 1st Special Forces Operational Detachment—Delta (Delta Force). The Tacoma, Washington 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 that is therefore 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 M1911-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 $380 for an imported Armscor/Rock Island model to more than $4,000 for the best competition or tactical models from such as those by Fusion Firearms, Rock River Armory (no longer in production), Wilson Combat, Ed Brown, Les Baer and Nighthawk Custom.
- Due to an increased demand for M1911 pistols among Army Special Operations units, who are known to field a variety of M1911 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 Special Operations units at Ft. Bragg and other locations. The project provided a feasibility study with insight into future projects. Models were loaned to various Special Operations 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 an M1911 platform in .40 which will incorporate lessons learned from the M1911 A2 project. Ultimately, the M1911 A2 project provided a test bed for improving existing M1911s. An improved M1911 variant becoming available in the future is a possibility.
- The Springfield Custom Professional Model 1911A1 pistol is produced under contract by Springfield Armory for the FBI regional SWAT teams and the Hostage Rescue Team. This pistol is made in batches on a regular basis by the Springfield Custom Shop, and a few examples from most runs are made available for sale to the general public at a selling price of approximately US$2,500 each.
MEU(SOC) Pistol
- Marine Expeditionary Units formerly issued M1911s to Force Recon units. 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, the Marines 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, but design and supply time was limited. 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.
Other Users
- Numbers of Colt M1911s 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.
- Norway used the Kongsberg Colt which was a license produced variant and is recognized by the unique slide catch. Many Spanish firearms manufacturers produced pistols derived from the 1911, such as the STAR Model P, the ASTRA 1911PL, and the Llama Model IX-A, just to name a few. Argentina produced a licensed copy, the Model 1927 Sistema Colt, which eventually led to production of the cheaper Ballester-Molina, which is based closely on the 1911.
- Germany Third Reich Home Guard used captured M1911s at the end of WWII under its German Wehrmachtswaffenamt weapon code 'Pistole 660 American' / P.660(a). The Brazilian company IMBEL (Indústria de Material Bélico do Brasil) still produces the .45 in several variants for military and law enforcement uses.
- The Greek Hellenic Army issues the M1911 as a sidearm. These are WWII production American pistols supplied as military aid in 1946 and afterward as the US aided Greece against Communist expansion.
- The Royal Thai Army still uses USGI M1911s that were supplied as military aid during the Vietnam War era.
- The Rapid Action Battalion (RAB Forces), an anti-terrorist tactical team in Bangladesh uses this weapon.
- The Armed Forces of the Philippines issues Mil-spec M1911A1 pistols as a sidearm to the special forces, military police and officers. These pistols are produced by Armscor and Colt.
- A Chinese Arms manufacturer, Norinco, exports a clone of the M1911A1 for civilian purchase. Importation into the US was blocked by trade rules in 1993. Norinco also manufactured conversion kits to chamber the 7.62x25mm Tokarev round after the Korean war.
Models
- Officially, there are two models of the gun: The original Model 1911 or simply M1911 (introduced in 1911) and the updated M1911A1 (introduced 1927, although transition models were introduced in 1924). The changes between the two were relatively minor, and consisted of details such as a shortened trigger and a longer grip safety tang, the latter to help protect the area between the user's thumb and forefinger from being pinched by the hammer when the gun was fired. Numerous other minor changes are made from time to time, but the gun is typically just referred to as an M1911.
Custom Models
- Since its inception, the M1911 has lent itself to easy customization. Replacement sights, grips, and other aftermarket accessories are the most commonly offered parts. Since the 1950s and the rise of competitive pistol shooting, many companies have been offering the M1911 as a base model for major customization. These modifications can range from changing the external finish, checkering the frame, and hand fitting custom hammers, triggers, and sears. Some modifications include installing compensators and the addition of accessories such as tactical lights and even scopes. These guns can cost over $5000 and are built from the ground up or on existing base models. The main companies offering custom Colt M1911s are: Fusion Firearms, Millennium Custom, Springfield Custom Shop, Ed Brown, Nighthawk Custom, Wilson Combat, Kimber, and Les Baer.
Civilian Models
- Colt Government Mk. IV Series 70 (1970-1983): Introduced the accurized Collet Barrel Bushing (1970-1988).
- Colt Government Mk. IV Series 80 (1983-?): Introduced an internal firing pin safety.
- Colt M1991A1 (1991-2001 ORM; 2001-Present NRM): A hybrid of the M1911A1 military model redesigned to use the slide of the Mk. IV Model 80. The 1991-2001 model used the old Colt rollmark engraved on the slide. The 2001 model introduced a new rollmark engraving.
- Browning's basic M1911 design has seen very little change throughout its production life. 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, including Kimber and Smith & Wesson, 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 have seen 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 USP, the M1911 shows no signs of decreasing popularity and continues to be widely present in various competitive matches such as those of IDPA, IPSC, and Bullseye.
- The slide stop pin of the 1911 can be depressed with firing if the index finger is placed along the side of the gun to assist in aiming the gun. That is an effective method of aiming which was known of since the early 19th century. Cautionary language against using that method of aiming and firing was included in the initial manual on the 1911 which was published in 1912. It also is found in other military manuals on the 1911 up to the 1940s.
Users
Brazil: The Brazilian Army uses a version of the M1911 developed by IMBEL chambered in 9x19mm Parabellum and designated M973.
Reliability
- It was the reliability of the 1911 that built its reputation as much as its stopping power. Its performance in the Army tests performed in 1911 (the gun was named after the year) set a record that was not beaten until a machine gun (also developed by Browning) broke it. The 1911 fired a continuous 6,000 rounds, stopped only for cooling, cleaning, and attempts to make it jam as it might on the battlefield.
Military Service
- The 1911 was the official military sidearm from 1911 until its retirement in 1985. Although it was replaced with the 9mm Beretta 52F (largely for conformance with NATO forces and its 15-round capacity), the U.S. military has not barred its forces from using the 1911. It continues to be used by special forces units which prefer its battlefield-proven pedigree.
