Abstract
A firearms magazine has compound tapered side walls and feed lips having substantially parallel end portions for maintaining contact with the cartridge as it is loaded. Removable inserts reduce the interior length and width to hold cartridges of different sizes. One insert has a channel along its height to protect the cartridge noses, and is held by a reinforcing member. A movable cartridge follower feeds the cartridges out of the magazine and has a pair of projections extending along its length for contacting and centering the last cartridge and a projection at one end slideable in the channel of the insert. The follower has one or more downwardly extending members to contact the floor or walls to maintain position of the follower with respect thereto. Projections extending inward from the side walls contact shoulders of the firearms cartridges in sliding relationship as they are fed out of the magazine.
