Abstract

The trigger of a handgun is retained and stabilized for longitudinal sliding movement between ready and firing positions within an upwardly opening guideway in the gun frame by longitudinally spaced apart lugs which project from the trigger into a guide track formed in the frame and opening laterally into the guideway. When the trigger is in an assembly position relative to the frame one of the lugs is vertically aligned with an upwardly and laterally inwardly opening notch in the frame which communicates with the guideway and the guide track. A pin carried by the trigger and engageable with an abutment on the frame prevents movement of the trigger to its assembly position after assembly with the frame.
