A weapon grip includes a grip body and a cross-sectionally generally U-shaped grip shell, each having opposite side walls and a rear wall interconnecting the side walls. The grip shell which is a one-piece component, is readily removably and replaceably inserted on the grip body in an installed position such that the walls of the grip body face the respective walls of the grip shell. The grip body and the shell body carry respective first and second abutment faces extending parallel to the length dimension of the grip body. The first and second abutment faces are in contact with one another in the installed position. First and second guides are formed on the grip body and the grip shell, respectively, and are disposed relative to one another and relative to the first and second abutment faces such that during motion of insertion of the grip shell on the grip body parallel to the length dimension, the first and second guides are in sliding engagement with one another and, by camming action, shift the grip shell relative to the grip body in a direction transverse to the length dimension for causing the first abutment face to arrive into contact with the second abutment face upon conclusion of the motion of insertion.

Replaceable weapon grip

A silencer for use with pistols with a fixed or tilting barrel. The design configuration is such that the sighting line is retained when the silencer is fitted. Handleability of the weapon is not seriously adversely affected by the design configuration and the lightweight structure.

Silencer for firearms

A safety mechanism to prevent the accidental discharge of a firearm such as an automatic pistol when the firearm impacts on a hard surface utilizes a second spring loaded slide bolt as an impact safety in addition to a conventional, trigger-activated spring biased slide bolt. The second safety bolt and its bias spring are structured and located so that an impact which causes the trigger-activated safety bolt to move out of its normal 'safety-on' position also causes the second slide to move against its bias spring to engage a recess on a firing pin and thereby prevent the weapon from firing. Also, when the firing pin is located in a slide of an automatic pistol, the slide, firing pin and hammer are structured so that a movement of the slide on impact towards the hammer causes the rear edge of the slide to strike the hammer with the firing pin spaced from the hammer.
