About the Cartridge

Initially introduced in Europe, this semi-rimmed centerfire cartridge came to the United States when Colt introduced its 'Pocket Model' semiautomatic pistol. Like the .25 ACP, the .32 ACP is considered by many as too weak to be an effective self-defense round. But it has been an extremely popular caliber, notably by the fact that practically all minor and major manufacturers of autoloading handguns in the world have built millions of small pocket autoloaders in .32 Auto.
