Abstract
An extended capacity cartridge magazine assembly for containing and feeding cartridges to a firearm is disclosed. The magazine includes a metal body for containing cartridges having an upper outlet through which cartridges may exit the magazine into the firing chamber of the firearm and a base plate for covering the bottom of the magazine body. A follower body is disposed within the body of the magazine for biasing cartridges toward the upper outlet. The follower body and the magazine body have certain dimensions to prevent an unwanted amount of rotation of the follower body when 0.45 caliber cartridges are being used. A collar slidably movable along the length of the magazine body is adapted to retain the base plate in a fixed position with respect to the magazine body. A flexible bumper plate interconnects with the bottom surface of the collar to secure the cartridge magazine assembly.
