Colt Model 723

[Diante Scharsch]

Designedby John Browning, the M1911 is the best-known of his designs to use the short recoil principle in its basic design. The pistol was widely copied, and this operating system rose to become the preeminent type of the 20th century and of nearly all modern centerfire pistols. It is popular with civilian shooters in competitive events such as the International Defensive Pistol Association and International Practical Shooting Confederation.[15]

The U.S. military procured around 2.7 million M1911 and M1911A1 pistols during its service life. The pistol served as the standard-issue sidearm for the United States Armed Forces from 1911 to 1985.[16] It was widely used in World War I,[17] World War II, the Korean War, and the Vietnam War. The M1911A1 was replaced by the adoption of the 9mm Beretta M9 pistol as the standard U.S. military sidearm in 1985. However, the U.S. Army did not officially replace the M1911A1 with the Beretta M9 until October 1986; production and procurement delays kept the 1911A1 in service with some units past 1989. The 1911A1 has never been completely phased out. Modernized derivative variants of the M1911 are still in use by some units of the U.S. Army Special Forces, U.S. Marine Corps and the U.S. Navy.

The United States was adopting new firearms at a phenomenal rate; several new pistols and two all-new service rifles (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.[citation needed]

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 the official adoption of the M1911 after the turn of the decade.[citation needed]

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.[19]

This led to a purchase of 1,000 DWM Luger pistols, chambered in 7.65mm Luger. 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 919mm Parabellum with fifty weapons chambered for it tested by the U.S. Army in 1903.[20]

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.[22] This led to the 1906 trials of pistols from six firearms manufacturing companies (namely, Colt, Bergmann, Deutsche Waffen und Munitionsfabriken (DWM), Savage Arms, Knoble, Webley, and White-Merrill).[22]

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.[22]

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 in 1917 to "Model 1911", and then "M1911" in the mid-1920s. The Director of Civilian Marksmanship began manufacture of M1911 pistols for members of the National Rifle Association of America in August 1912. Approximately 100 pistols stamped "N.R.A." below the serial number were manufactured at Springfield Armory and by Colt.[24] The M1911 was formally adopted by the U.S. Navy and Marine Corps in 1913. The .45 ACP "Model of 1911 U.S. Army" was used by both U.S. Army Cavalry troops and infantry soldiers during the United States' Punitive Expedition into Mexico against Pancho Villa in 1916.[25]

By the beginning of 1917, a total of 68,533 M1911 pistols had been delivered to U.S. armed forces by Colt's Patent Firearms Manufacturing 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 and North American Arms Co. of Quebec.[26] Several other manufacturers were awarded contracts to produce the M1911, including the National Cash Register Company, the Savage Arms Company, the Caron Brothers Manufacturing 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.[27]

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.[28] 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).[22] These changes were subtle and largely intended to make the pistol easier to shoot for those with smaller hands. No significant internal changes were made, and parts remained interchangeable between the M1911 and the M1911A1.[22]

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.[22] As the Colt Service Ace, this was available both as a pistol and as a conversion kit for .45 M1911 pistols.[22]

Before World War II, 500 M1911s were produced under license by the Norwegian arms factory Kongsberg Vaapenfabrikk, as Automatisk Pistol Model 1912. Then, production moved to a modified version designated Pistol Model 1914 and unofficially known as "Kongsberg Colt". The Pistol M/1914 is noted for its unusual extended slide stop which was specified by Norwegian ordnance authorities. Twenty-two thousand were produced between 1914 and 1940 but production continued after the German occupation of Norway in 1940 and 10,000 were produced for the German armed forces as Pistole 657 (n). [29]

The M1911 and M1911A1 pistols were also ordered from Colt or produced domestically in modified form by several other nations, including Brazil (M1937 contract pistol), Mexico (M1911 Mexican contract pistol and the Obregn pistol), and Spain (private manufacturers Star and Llama).[citation needed]

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 bluing, and the wood grip panels were replaced with panels made of brown plastic. The M1911A1 was a favored small arm of both U.S. and allied military personnel during the war, in particular, the pistol was prized by some British commando units and Britain's highly covert Special Operations Executive, as well as South African Commonwealth forces.[30][31][32]

The M1911A1 pistol was produced in very large quantities during the war. At the end of hostilities the government cancelled all contracts for further production and made use of existing stocks of weapons to equip personnel. Many of these weapons had seen service use, and had to be rebuilt and refinished prior to being issued. From the mid-1920s to the mid-1950s thousands of 1911s and 1911A1s were refurbished at U.S. arsenals and service depots. These rebuilds consisted of anything from minor inspections to major overhauls. Pistols that were refurbished at government arsenals will usually be marked on the frame/receiver with the arsenal's initials, such as RIA for Rock Island Armory or SA for Springfield Armory.[citation needed]

From 1943 to 1945 a fine-grade russet-leather M1916 pistol belt set was issued to some generals in the U.S. 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 lanyard. The metal buckle and fittings were in gilded brass. The buckle had the seal of the U.S. 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 U.S. Army and U.S. 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.

After World War II, the M1911 continued to be a mainstay of the U.S. Armed Forces in the Korean War and the Vietnam War, where it was used extensively by tunnel rats.[34] 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.[35]
