The official US military designation for the Colt .45 semiautomatic pistol adopted by the US in 1911.
The gun was designed by John Moses Browning, and produced by Colt.
During trials, the Browning-Colt design beat out several competing designs, including one from Savage and a .45 caliber version of the German Parabellum ("Luger").
The M1911 saw its first combat in the Philippines and then in World War I.
Early use showed that it could be improved and in 1921 the M1911A1 was introduced, which featured a few changes like a reocontoured frame,
shorter trigger, and a rounded backstrap. The M1911A1 remained the standard US military handgun until it was replaced in the 1980's by the Beretta M9.

conform to more modern theories of handgun usage.
