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. It is popular with civilian shooters in competitive events such as IDPA, International Practical Shooting Confederation, and Bullseye shooting.
The history of the M1911 began in the early 1900s, when famous designer John M. Browning began developing semi-automatic pistols for Colt. In 1906-1907 the US Army announced trials to replace its service revolvers with new, semi-automatic pistols. The Army required the pistol to have a caliber of .45. So Browning designed its own cartridge that fired 230 grains bullet, and then, designed a new pistol. In 1911, after extensive testings, the new pistol and its cartridge, designed by Browning and manufactured by Colt, were adopted for U.S. military service as the M1911. Prior to and during World War I, more than one million of these guns were manufactured, mostly by Colt and Springfield Armory, as well as by Remington-UMC, Burroughs, Savage and some other companies. The rights to manufacture Colt/Browning design were also sold to some foreign countries, such as Norway and Argentine.
In 1926, original design was improved, following the recommendations of the US Army Ordnanve Dept. The improved design was adopted by the US Military as the M1911A1 pistol, and served with distinction until the mid-1980s, when it was officially replaced in service with M9 pistol.
