ABSTRACT:
A passive safety mechanism is shown installed in a semi-automatic pistol. The passive safety mechanism includes a cylindrical body rotatably mounted within the slide assembly which may be rotated between an engaged position and a disengaged position using a key inserted into a keyway in the exposed axial end of the cylindrical body. In the engaged position, a portion of the body blocks the hammer assembly from contacting the firing pin, and a circumferential surface depresses the ejector and magazine depressor lever and firing pin safety lever. Rotation of the cylindrical body within the slide assembly is prevented or resisted through friction and spring tension created by a spring-biased pin carried in a transverse bore in the cylindrical body and riding within a channel in the slide assembly. One or both of the axial ends of the cylindrical body may be recessed from the sides of the slide assembly, polished to further prevent or evidence tampering, and the axial end opposing the keyway may optionally be covered. The semi-automatic pistol thereby has no manual safety lever.
