This cartridge was introduced by Winchester in 1979 to be used in the gas-operated Wildey pistol. Winchester's new pistol was not much of a success, but the powerful .45 Winchester Magnum cartridge was. The cartridge is essentially an elongated version of the .45 ACP round. It was the most powerful semi-auto cartridge of its time, until the introduction of the .50 Action Express in 1988.
