Designed in 1911 by John Moses BROWNING enterprises, this weapon is the base colt 1911. He was adopted by the USA on 23 March 1911. At the end of the first world war, colt 1911 is amended, then appears the Colt 1911A1. These amendments are:
-Shortening of the relaxation,
-The swelling of the part rear hook (under the pedal with safety),
-The notch of the handle part and of relaxation,
-Elongation of the sight at the end of the barrel,
-Change of form to the placement of the screws on the handle (1911 = round / / / 1911A1 = diamond form)
It is estimated that at the end of the second world war, more than 2.5 million Colt had been manufactured. Its ammunition of 45ACP earned him his nickname of "45". The cartridge was also used for other regulatory weapons such as the Thomson or the M3.
Distributed to officers and ammunition providers, other IM had in their possession, having done everything to have one. This weapon will be the regulatory gun of the U.S. Army until 1985 (there will be of course changes back into day...).
