Abstract: Safety devices for use with a handheld firearm are disclosed. The safety devices include a lever that can be pivoted into the travel path of the hammer of the firearm to preclude the hammer from striking a firing pin. In an example, the lever is connected to the trigger such that the safety device is released when the trigger is pulled. In another example, the lever protrudes into the magazine shaft of the firearm such that the safety device is only released when a magazine is inserted into the shaft.

Abstract: A mounting apparatus is disclosed for attaching a sighting device onto a weapon. The mounting apparatus has a rail disposed on part of the weapon in a longitudinal direction. The rail has a pair of longitudinally extending opposed sides and a longitudinally extending first attachment element on each of the opposed sides. A removable mounting base has a pair of longitudinally extending side edges and a longitudinally extending second attachment element on each side edge. Each second attachment element is complimentary to a corresponding one of the first attachment elements. The mounting base is slidingly and longitudinally engaged with the rail via the complimentary first and second attachment elements. The mounting base is formed of at least two parts which are slidable against one another in a transverse direction. A spring mechanism produces a spring force and is arranged to bias the two parts of the mounting base into engagement with the rail.

Abstract: Apparatus and methods are disclosed for releasably securing a retractable shoulder stock relative to the casing of a firearm. The retractable shoulder stock includes a slide rail which is displaceable relative to the casing. The slide rail defines a recess. The shoulder stock also includes a catch lever which is mounted for rotation about an axis. The catch lever has a peripheral surface that can be manually engaged to rotate the catch lever about the axis. The catch lever is positioned to selectively engage in the recess to releasably lock the slide rail in a first predetermined position.
