Abstract
A cartridge magazine having a slidably removable bottom cover which slides on a pair of flange slide rails on the bottom end of the hollow main cartridge-holding body of the magazine, to enable assembly and removal of the cover. Cam stops and end stops are formed on elastically flexible opposite side walls of the body, and are engagable in releasable locking relation by inturned lock lips which ride in sliding relation on the flange slide rails. The lock lip means are movable over the cam lock stops by depression of the flexible outer walls during assembly and removal of the cover, being cam depressed during assembly and being positively manually depressed for disassembly removal. A cartridge feed spring acts in conjunction with the curvature of the main body and a key tab on the bottom cover to exert a small removal-acting lateral force on the cover.
