ABSTRACT:
The apparatus of the invention is adapted to be used in a firearm of the type having a body having an interior space, a hammer supported for movement by the body, and a trigger for actuating the hammer. A strut member is located in the interior space of the body and has one end pivotally connected to the hammer. A movable bridge member, located in the interior space of the body, is coupled to the body for movement between first and second positions toward and away from the hammer respectively. The bridge member has an opening for freely receiving the opposite end of the strut member. A coiled spring is located around the strut member and has an end adapted to engage the structure of the strut member near its point of connection to the hammer and an opposite end adapted to engage the bridge member. An opening is formed through wall structure of the body in line with the bridge member. A movable keeper is provided which may be located through the opening for engaging the bridge member and moving it to its first position for containing the spring and allowing spring compression to occur against the hammer allowing it to fire the weapon when actuated by the trigger. A releasable means is provided for releasably holding the keeper in its enabling position. When the releasable means is released, the keeper is allowed to be moved away from its enabling position to allow the bridge member to move to its second position for releasing spring compression to disable the firearm.
