When it comes to the world of shooting, there’s nothing more iconic than the infamous Colt M1911. Developed in 1904 and 1905 by John Browning, the .45 ACP was designed to be the semi-auto version of the .45 caliber. It was actually the U.S. Military that originally requested an updated round. General John Thompson was quoted as saying that he wanted a “real man stopper” pistol. This was after the ineffectiveness of the .38 in the Philippine-American War.
John Browning, working for the weapons manufacturer Colt, was the mastermind, but the .45 caliber wasn’t his first option. In fact, he had been working on a .41 caliber before the military decided, after testing several caliber sizes, that the .45 was the proper size. It started out being filled with 200 grains of powder behind a 13-gram bullet. This round reached a velocity of 900 feet per second.
However, after more intense testing, the round was adapted to have 230 grain powder with a 14.9-gram bullet. This is the round that became known as the .45 ACP. Though the round is still extremely popular, and used by many agencies around the world, many are still switching to the 9mm strictly based on cost and the amount of rounds available in the gun.
