ABSTRACT:
A cartridge feeding drum magazine for use with semiautomatic or full-automatic firearms such as pistols or submachine guns. A rotor is provided within a drum housing to define an annular cartridge-receiving channel, and a magazine extension joins the drum at 90.degree. thereto for insertion within the existing magazine receptacle of a firearm. The rotor, which is spring-biased for rotation, carries a separate magazine spring within a housing, so that the magazine spring remains enclosed while the rotor turns to feed cartridges. The magazine spring moves out of its housing to urge remaining cartridges through the magazine extension, after cartridge-feeding movement of the rotor is completed.
