The Colt M1911 is a semi-automatic, magazine-fed, single-action .45 caliber handgun. John Browning sold the original design to Colt, when it became the standard-issue side arm for the United States Armed Forces from 1911 to 1985, and modernized variants of the M1911 are still carried by some US special forces units today, although it was largely phased out in favor of the M9 pistol. It fires the .45 ACP round, which causes more tissue disruption than the 9mm Parabellum, but has more recoil and has lower ammunition capacity when compared to similarly sized 9mm handguns. It is used by Alliance of Nations, the Axis of Empires and the Coalition of Independent States
