摘要： A trigger release mechanism is disclosed which changes the action of the factory trigger mechanism by moving the pivot point of the trigger forward through the use of an extension fork extending forwardly of the factory trigger base. In normal movement, with the factory pivot point, as the trigger is pulled rearward, the trigger actuated end of the sear is pulled downwardly, lifting the hammer engaging end of the sear to disengage the hammer and allow the hammer to fall. However, by changing this pivot point, the sear catch of the trigger actuated linkage indexes on the trigger actuated end of the sear only when the trigger is pulled backwardly. Spring tension from a spring plunger absorbs the potential energy caused by the upward movement of the trigger base. Upon release of finger pressure on the trigger, the spring loaded plunger releases kinetic energy to furnish the downward thrust to force the trigger actuated end of the sear downwardly so as to raise the hammer engagement end of said sear out of engagement with the hammer and release same.
