  • Patent number: 5388362
    Abstract: An auxiliary safety device intended for use as a magazine safety with a semi-automatic pistol of the Makarov design, said pistol being a blowback-operated, magazine-fed that is operable in double-action or single-action modes. The pistol's factory-original parts include a sear that pivots with respect to the pistol's frame about an axis that is defined by a transverse support post. The pistol has a sear cam that operates on the hammer in double-action operation, and operates on the sear in single-action operation. The auxiliary safety device includes two parts, the first being a relatively thin structural plate having front and rear portions. A relatively large and generally circular opening is located about midway between the front and rear portions; the opening is large enough to fit around and rotate with respect to the transverse post.

  • Patent number: 4593487
    Abstract: The pistol handle has a recess for housing a mainspring housing which is also a lanyard loop body and hammer strut unit in a releasable catch arrangement. The lanyard loop body, hammer strut, and mainspring are telescopically aligned and are withdrawn from the pistol as a unitized system during disassembly. Connector means between the loop body and strut are operative only during disassembly to prevent separation of the loop body and strut upon their removal from the pistol handle. The unit is secured in the handle recess through a bayonet joint and the unit may be turned and removed only when the magazine has been previously withdrawn.

  • Patent number: 4575963
    Abstract: A frame-mounted firing pin blocking piece for blocking a semi-automatic pistol firing pin which blocking piece at all times blocks the firing pin except just prior to and at firing. The blocking piece is rotated to its unblocking position by action of a trigger bar which bar is in turn positioned by the trigger and the firearm slide. A sear associated with the firing pin blocking piece permits such operation in single action, double action and re-set modes.
