A magazine and compact feed mechanism for firearms includes an end cap on the magazine to keep cartridges from falling out and a stop mechanism for preventing a rotating cartridge transfer disk from traveling beyond 90°. The magazine is placed in a horizontal position so that it is parallel to the barrel and includes an end cap that is shaped to prevent cartridges from inadvertently falling out of the magazine. A spring-loaded cover may also be added to the magazine for further protection. Cartridges from the magazine are delivered to a rotatable transfer disk by an injector arm driven by the recoil of the slide mechanism. A rotatable cartridge transfer disk is also driven by the recoil of the slide mechanism and functions to receive the cartridge from the horizontal magazine and rotate it 90° so as to present it properly to the breech mechanism so that it can be presented to the barrel. In order to prevent the rotating transfer disk from traveling beyond 90°, as might be the case with high power ammunition, the slide and transfer disk include a mechanism to stop the transfer disk from rotating after precisely 90° of rotation.
In an improved magazine and feed mechanism for firearms having a housing defining a barrel extending longitudinally there along, a means for holding a magazine mounted thereon and adapted to hold a plurality of cartridges extending laterally with respect to the housing and positioned to be urged from the magazine in successively following order outwardly through a cartridge outlet defined therein, a transfer disk rotatably mounted within the housing and including a cartridge receiving slot adapted to receive successive cartridges oriented laterally one at a time from the magazine positioned thereadjacent, the transfer disk being rotatable between a laterally oriented cartridge receiving position and the longitudinally oriented cartridge supplying position, and a rail member longitudinally movable between a forward position adjacent the barrel to a rearward position spatially disposed away from the barrel and a cartridge injector for transferring cartridges from said magazine to said transfer disk, the improvement comprising:
