ABSTRACT:
A gun magazine including a magazine body for holding a series of rounds of ammunition, and a floor plate at the lower end of the magazine body detachable therefrom by generally horizontal sliding movement relative to the body, with the floor plate preferably containing a recess extending downwardly into the floor plate beneath the lower extremity of the magazine body and into which the main ammunition follower spring projects downwardly. The floor plate may be connected to the magazine body loosely, in a manner enabling slight upward and downward shifting movement of the plate relative to body, and be provided with locking means for blocking lateral separation of the floor plate from the magazine body but adapted to be released to permit such separation by a slight shifting movement of the floor plate against the tendency of the main follower spring. The follower itself which is urged upwardly by that spring, to advance the ammunition upwardly, is releasably retained in a lower position by a spring pressed latching element to facilitate loading of rounds into the magazine.
