ABSTRACT:
The magazine, which is usable specifically for hand guns, is capable of storing cartridges of various sizes, i.e. diameters. The magazine lips are bent inwards with such a curvature that their inner surface defines part of a jacket of a cylinder, which has a diameter which corresponds substantially to the diameter of the base of the largest cartridge which the magazine can store. The uppermost edges of these magazine lips extend at an angle relative to each other such that they diverge in the firing direction of the magazine. The distance between these edges is at any point along their extent smaller than the diameter of the smallest cartridge which can be stored in the magazine. A spring biassed feeder within the magazine has a cartridge support surface, which includes a bulged surface section. This bulged surface section ensures a line contact with any size cartridge or shell, respectively, which is stored in the magazine. Accordingly, a cartridge which is loaded into the chamber of the gun is guided by two diverging fixed guides, namely the upper edges of the lips and one movable guide. This allows a handling of cartridges of various sizes without a jamming when loading.
