ABSTRACT:
A trigger assembly for a gun comprises a trigger, a hammer mounted adjacent the trigger, a spring-biased member urging the hammer into a firing position, a sear on the trigger to hold the hammer in a cocked position, an auxiliary sear mounted on the trigger to engage the hammer in event the hammer is urged into a cocked position before the trigger is released, an adjustable spring-biased member attached to the auxiliary sear to permit adjustment of the auxiliary sear, and an adjustable elongated spring-biased component positioned longitudinally adjacent a lower portion of the trigger assembly and having one end impinging a front lower face of the trigger to permit fine adjustment of trigger movement. The adjustable spring-biased member attached to the auxiliary sear includes a hook member removably positioned upon the auxiliary sear, a threaded adapter positioned in the lower portion of the trigger assembly, and a spring connecting the hook member to the threaded adapter. The threaded adapter includes a threaded outer member positioned adjacent the trigger assembly and a threaded bolt received cooperatively in the threaded outer member. The cooperation of the components provides adjustment of the trigger tension and adjustment or reduction in the amount of creep in the trigger mechanism.
