The M1911 pistol originated in the late 1890s as the result of a search for a suitable self-loading (or semi-automatic) pistol to replace the variety of revolvers then in service. The United States was adopting new firearms at a phenomenal rate; several new pistols 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 rifle in the 1880s, but was preoccupied with machine guns. Nevertheless, the application of his principle of using cartridge energy to reload led to several self-loading pistols in 1896. 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 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 Mannlicher M1894), and Colt (the Colt M1900).
This led to a purchase of 1,000 DWM Luger pistols, chambered in 7.65mm Luger, a bottlenecked cartridge. During field trials these ran into some problems, especially with stopping power. Other governments had made similar complaints. Consequently, DWM produced an enlarged version of the round, the 9×19mm Parabellum (known in current military parlance as the 9×19mm 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.
American units fighting Moro guerrillas during the Philippine–American War using the then-standard Colt M1892 revolver, .38 Long Colt, found it to be unsuitable for the rigors of jungle warfare, particularly in terms of stopping power, as the Moros had high battle morale and often used drugs to inhibit the sensation of pain. The U.S. Army briefly reverted to using the M1873 single-action revolver in .45 Colt caliber, which had been standard during the late 19th century; the heavier bullet was found to be more effective against charging tribesmen. The problems 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 .45 ACP (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 test at the end of 1910 attended by its designer, John Browning. Six thousand 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.
Following its success in trials, the Colt pistol was formally adopted by the Army on March 29, 1911, when it was designated Model of 1911, later changed to Model 1911, in 1917, and then M1911, in the mid-1920s. The Director of Civilian Marksmanship began manufacture of M1911 pistols for members of the National Rifle Association in August 1912. Approximately 100 pistols stamped "N.R.A." below the serial number were manufactured at Springfield Armory and by Colt. The M1911 was formally adopted by the U.S. Navy and Marine Corps in 1913.
By the beginning of 1917, a total of 68,533 M1911 pistols had been delivered to U.S. armed forces by Colt Firearms Company and the U.S. government's Springfield Armory. However, the need to greatly expand U.S. military forces and the resultant surge in demand for the firearm in World War I saw the expansion of manufacture to other contractors besides Colt and Springfield Armory, including Remington-UMC, North American Arms Co. of Quebec. Several other manufacturers were awarded contracts to produce the M1911, including the National Cash Register Company, the Savage Arms Company, the Caron Bros. of Montreal, the Burroughs Adding Machine Co., Winchester Repeating Arms Company, and the Lanston Monotype Company, but the signing of the Armistice resulted in the cancellation of the contracts before any pistols had been produced.
Battlefield experience in World War I led to some more small external changes, completed in 1924. The new version received a modified type classification, M1911A1, in 1926 with a stipulation that M1911A1s should have serial numbers higher than 700,000 with lower serial numbers designated M1911. The M1911A1 changes to the original design consisted of a shorter trigger, cutouts in the frame behind the trigger, an arched mainspring housing, a longer grip safety spur (to prevent hammer bite), a wider front sight, a shortened hammer spur, and simplified grip checkering (eliminating the "Double Diamond" reliefs). These changes were subtle and largely intended to make the pistol easier to shoot for those with smaller hands. Many persons 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 M1911 and the M1911A1.
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 pistol and as a conversion kit for .45 M1911 pistols.
Before World War II, a small number of modified M1911-pattern pistols in .45 caliber were produced under license at the Norwegian weapon factory Kongsberg Vaapenfabrikk, designated "Pistol M/1914" and unofficially known as "Kongsberg Colt". Production continued after the German occupation of Norway in 1940. The Pistol M/1914 is noted for its unusual extended slide stop which was specified by Norwegian ordnance authorities. Throughout the M/1914's use in Norwegian military service, Norway continued to build the M/1914 pistol as originally specified. These pistols are highly regarded by modern collectors, with the 920 examples stamped with German Army inspectors proof (Waffenamt) codes and the unknown number of unmarked examples assembled by the Norwegian resistance movement (the "Matpakke-Colt" or "Lunch Box Colt") being the most sought after. German forces also used captured M1911A1 pistols, using the designation "Pistole 660(a)".
The M1911 and M1911A1 pistols were also ordered from Colt or produced domestically in modified form by several other nations, including Argentina (Modello 1916 and Modello 1927 contract pistols, and the Ballester–Molina), in Brazil by the M1937 contract pistol, in Mexico by M1911 Mexican contract pistols and the Obregón, and in Spain by private manufacturers Star and Llama.
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). New M1911A1 pistols were given a parkerized metal finish instead of blueing, and the wood grip panels were replaced with panels made of brown plastic. The M1911A1 was a favored small arm of both US and allied military personnel during the war, in particular, the pistol was prized by some British commando units and the SOE as well as Commonwealth South African forces.
So many 1911A1 pistols were produced during the war that the government cancelled all postwar contracts for new production, instead choosing to rebuild existing pistols with new parts, which were then refinished and tested for functioning. From the mid-1920s to the mid-1950s thousands of 1911s and 1911A1s were refurbished at U.S. Arsenals and Service depots. These arsenal rebuilds consisted of anything from minor inspections to major overhauls of pistols returned from service use. Pistols that were refurbished at Government arsenals will usually be marked on the frame/receiver with the arsenal's initials, such as RIA (Rock Island Armory) or SA (Springfield Armory).
Among collectors today, the Singer-produced pistols in particular are highly prized, commanding high prices even in poor condition.
From 1943 to 1945 a fine-grade russet-leather M1916 pistol belt set was issued to some generals in the US Army. It was composed of a leather belt, leather enclosed flap-holster with braided leather tie-down leg strap, leather two-pocket magazine pouch, and a rope neck lanyard. The metal buckle and fittings were in gilded brass. The buckle had the seal of the United States on the center (or "male") piece and a laurel wreath on the circular (or "female") piece. The pistol was a standard-issue M1911A1 that came with a cleaning kit and three magazines.
From 1972 to 1981 a modified M1911A1 called the RIA M15 General Officer's Model was issued to General Officers in the US Army and US Air Force. From 1982 to 1986 the regular M1911A1 was issued. Both came with a black leather belt, open holster with retaining strap, and a two-pocket magazine pouch. The metal buckle and fittings were similar to the M1916 General Officer's Model except it came in gold metal for the Army and in silver metal for the Air Force. The M15 and M1911A1 were replaced with the M9 pistol in 1986.
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 used during Desert Storm in specialized U.S. Army units and U.S. 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 Congress to standardize on a single modern pistol design, the U.S. Air Force ran a Joint Service Small Arms Program to select a new semi-automatic pistol using the NATO-standard 9 mm 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 despite a problem with slide separation using higher-than-specified-pressure rounds that resulted in injuries to some U.S. 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 Beretta M9, though a limited number remain in use by special units. The U.S. Marine Corps (USMC) 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 pistols). For its part, the United States Special Operations Command (USSOCOM) issued a requirement for a .45 ACP pistol in the Offensive Handgun Weapon System (OHWS) trials. This resulted in the Heckler & Koch OHWS becoming the MK23 Mod 0 Offensive Handgun Weapon System (itself being heavily based on the 1911's basic field strip), beating the Colt OHWS, a much modified M1911. Dissatisfaction with the stopping power of the 9 mm Parabellum cartridge used in the Beretta M9 has actually promoted re-adoption of pistols based on the .45 ACP cartridge such as the M1911 design, along with other pistols, among USSOCOM units in recent years, though the M9 remains predominant both within SOCOM and in the U.S. military in general.
Many military and law enforcement organizations in the United States and other countries continue to use (often modified) M1911A1 pistols including Marine Corps Special Operations Command, Los Angeles Police Department SWAT and S.I.S., the FBI Hostage Rescue Team, FBI regional SWAT teams, and 1st Special Forces Operational Detachment—Delta (Delta Force).
The M1911A1 is 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 around $400 for basic pistols imported from the Philippines or Turkey (Armscor, Tisas, Rock Island Armory, Girsan, STI Spartan, Seraphim Armoury) to more than $4,000 for the best competition or tactical versions (Wilson Combat, Ed Brown, Les Baer, Nighthawk Custom, and STI International).
Due to an increased demand for M1911 pistols among Army Special Operations units, who are known to field a variety of M1911 pistols, the U.S. 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 pistol in .40 which will incorporate lessons learned from the A2 project. Ultimately, the M1911A2 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$2,700 each.
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.
In late July 2012, the U.S. Marines placed a $22.5 million order for 12,000 M1911 pistols for MEU(SOC) forces. The new 1911 was designated M45A1 or "Close Quarters Battle Pistol" CQBP. The M45A1 features a dual recoil spring assembly, Picatinny rails and is cerakoted tan in color.Bangladesh still uses USGI M1911s supplied as military aid during the Vietnam War era while Rapid Action Battalion (RAB Forces), an anti-terrorist police tactical team in Bangladesh uses this weapon.
The Brazilian company IMBEL (Indústria de Material Bélico do Brasil) still produces the pistol in several variants for military and law enforcement uses in .45 ACP, .40 S&W and 9 mm calibres. The two former are also available to Army-registered collectors and shooters. For the civilian market, the pistols are chambered in .380 ACP since there are strong calibre restrictions in place. Also, produces for US civilian market as the supplier to Springfield Armory.
The Canadian company Seraphim Armoury brands Filipino manufactured pistols in several models for domestic and export use. Pistols are available in .45 ACP and 9 mm calibres for civilian, military and law enforcement use.
A Chinese Arms manufacturer, Norinco, exports a clone of the M1911A1 for civilian purchase as the M1911A1 and the high-capacity NP-30, as well 9mm variants the NP-28 and NP-29. Norinco also manufactured conversion kits to chamber the 7.62×25mm Tokarev round after the Korean War.
As of 2013, the pistol is made under license instead of copying with Colt manufacturing machinery, due to an agreement between Norinco and Colt in order to stop Norinco from producing the Norinco CQ rifle. Importation into the United States was blocked by trade rules in 1993 but Norinco still manages to import the weapon into Canada and successfully adopted by IPSC shooters, gunsmiths and firearms enthusiasts there because of the cheaper price of the pistol than the other M1911s.
The German Volkssturm used captured M1911s at the end of World War II under the weapon code P.660(a), in which the alphabet means "Amerika", the weapons' origin country.
The Greek Hellenic Army issues the World War II production American M1911 as sidearm. These pistols are supplied as military aid in 1946 and afterward as the U.S. aided Greece against Communist expansion.
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 1911, such as the STAR Model B, the ASTRA 1911PL, and the Llama Model IX, 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 resembles the 1911, but is not actually based on it.
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 mostly produced by Colt, though some of them are produced locally by Armscor, a Philippine company specialized in making 1911-style pistols. The Indonesian Army issued a locally produced version of the Springfield M1911, chambered in .45 ACP along with the Pindad P1, the locally manufactured Browning Hi-Power pistol as the standard issue sidearm.
In the 1950s, the Republic of China Army (Taiwan) used original M1911A1s, and the batches are now still used by some forces. In 1962, Taiwan copied the M1911A1 as the T51 pistol, and it saw limited use in the Army. After that, the T51 was improved and introduced for export as the T51K1. Now the pistols in service are replaced by locally-made Beretta 92 pistols- the T75 pistol.
The Royal Thai Army and Royal Thai Police uses the Type 86, the Thai copy of the M1911 chambered in the .45 ACP round,
The Turkish Land Forces uses "MC 1911" Girsan made copy of M1911.
Numbers of Colt M1911s were used by the Royal Navy as sidearms during World War I in .455 Webley Automatic caliber. The pistols 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.
Colt Government Mk. IV Series 70 (1970–1983): Introduced the accurized Split Barrel Bushing. The first 1000 prototypes in the serial number range 35800NM – 37025NM were marked BB on the barrel and the slide. Commander sized pistols retained the solid bushing.
Colt Government Mk. IV Series 80 (1983–present): Introduced an internal firing pin safety and a new half-cock notch on the sear; pulling the trigger on these models while at half-cock will cause the hammer to drop. Models after 1988 returned to the solid barrel bushing due to concerns about breakages.
Colt 1991 Series (1991–2001 ORM; 2001–present NRM): A hybrid of the M1911A1 military model redesigned to use the slide of the Mk. IV Model 80; these models aimed at providing a more "mil-spec" pistol to be sold at a lower price point than Colt's other 1911 models in order to compete with imported pistols from manufacturers such as Springfield Armory and Norinco. The 1991–2001 model used a large "M1991A1" rollmark engraved on the slide. The 2001 model introduced a new "Colt's Government Model" rollmark engraving. The 1991 series incorporates full-sized blued and stainless models in either .45 ACP or .38 Super, as well as blued and stainless Commander models in .45 ACP.
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. A common modification of John Browning's design is to use a full-length guide rod that runs the full length of the recoil spring. This adds weight to the front of the pistol, but does not increase accuracy, and does make the pistol slightly more difficult to disassemble. Custom guns can cost over $5000 and are built from the ground up or on existing base models. The main companies offering custom M1911s are: Springfield Custom Shop, Ed Brown, STI International, Nighthawk Custom, Wilson Combat, and Les Baer. ISPC models are offered by both Strayer Voigt Inc (Infinity Firearms) and STI International.
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 rear of the barrel down, out of locking recesses in the slide, and the barrel is stopped by making contact with the lower barrel lugs against the frame's vertical impact surface. 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.
There are no fasteners of any type in the 1911 design, excepting the grip screws. The main components of 1911 are held in place by the force of the recoil spring. The pistol can be "field stripped" by partially retracting the slide, removing the slide stop, and subsequently removing the barrel bushing. Full disassembly (and subsequent reassembly) of the pistol to its component parts can be accomplished using several manually removed components as tools to complete the disassembly.
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. Language cautioning against pulling the trigger with the second finger was included in the initial M1911 manual, and later manuals up to the 1940s.
The same basic design has been offered commercially and has been used by other militaries. In addition to the .45 ACP (Automatic Colt Pistol), models chambered for .38 Super, 9×19mm Parabellum, 7.65mm Parabellum, 9mm Steyr, .400 Corbon, and other cartridges were 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 early 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, the Springfield XD 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 USPSA, IDPA, IPSC, and Bullseye.Cartridge: .45 ACP
Other commercial and military derivatives: Other versions offered include .22, .38 Super, 9×19mm Parabellum, .40 S&W, 10mm Auto, .400 Corbon, .460 Rowland, .22 LR, .50 GI, .455 Webley, 9×23mm Winchester, and others. The most popular alternative versions are 9×19mm Parabellum, .38 Super and 10mm Auto.
Barrel: 5 in (127 mm) Government, 4.25 in (108 mm) Commander, and the 3.5 in (89 mm) Officer's ACP. Some modern "carry" guns have significantly shorter barrels and frames, while others use standard frames and extended slides with 6 in (152 mm) barrels

Guns chambered in .38 Super and 9 mm have a 9+1 capacity. Some manufacturers, such as Armscor, Para Ordnance, Strayer Voigt Inc and STI International Inc, offer 1911-style pistols using double-stacked magazines with significantly larger capacities (typically 14 rounds). Colt makes their own 8 round magazines which they include with their Series 80 XSE models.
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 M1911A1s. 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.
On March 18, 2011, the U.S. state of Utah—as a way of honoring M1911 designer John Browning, who was born and raised in the state—adopted the Browning M1911 as the "official firearm of Utah".AMT Hardballer
