A drum magazine for a gun has a housing with a feed throat extending from the housing and within the housing are mounted concentric sprockets. The sprockets have serrations for nesting cartridges and each sprocket is independently rotatable with stops for limiting the rotation of the outer sprocket and stops limiting rotation of the intermediate sprocket. A latch is arranged to prevent rotation of the outer sprocket in a counter direction to the direction of feeding cartridges out of the magazine until the intermediate sprocket is rotated in the counter direction a predetermined amount. A connector is connected to the outer sprocket and passes through the outer sprocket to engage with the cartridges nested in the intermediate sprocket so that by virtue of the connector, the sprockets rotate together. A similar connector is provided between the intermediate sprocket and the inner sprocket. A U-shaped pusher is provided to push the last few remaining cartridges in the magazine out of the feed throat.
A drum magazine for a gun including a stationary housing, an inner rotatably mounted member and an outer rotatably mounted member substantially concentric therewith, drive means for rotating the members in a first direction, stop means for limiting rotation of the outer member with respect to the housing, and latch means between the outer member and the housing arranged to lock when the stop means limit the rotation of the outer member to thereby prevent rotation of the outer member in a counter direction to the first direction until the inner member is rotated in said counter direction a predetermined amount.
