A primer cartridge magazine is removably mounted in the reciprocally movable slider of a wedge-type breech mechanism of a gun. The magazine has a longitudinal spring mounted therein which biases a stack of primer cartridges via a guide member towards the bottom of the magazine at which bottom a primer cartridge inlet and outlet is disposed. The magazine has a pair of parallel opposite walls which define a widened top portion having a pair of indicating windows. An indicating disc is rotatably mounted by means of a composite shaft in the widened portion and indicates via the indicating windows by means of a plurality of numbers disposed on each face of the indicating disc the stock of primer cartridges in the magazine. A tension band is connected to the indicating disc and guide member. A first locking mechanism locks the indicating disc against rotation when the magazine is not assembled in the slider. A second locking mechanism locks the indicating disc against rotation during loading of the magazine.
