ABSTRACT:
A dual stage trigger assembly including a spring loaded hammer, a spring loaded trigger, a disconnect lever, a torsion spring adjustment plate, springs, and user available adjustment screws whereby a sear face of the trigger fully engages a notch in the hammer in cocked position; whereby a user available adjustment screw, without disturbing the assembly, allows a user to adjust a screw in a first end of the disconnect lever to adjust second stage trigger travel to set the length of engagement of the trigger sear with the hammer notch. At this point a contact face of the disconnect lever contacts a tang on the hammer and a user available adjustment screw in a second end of the disconnect lever compressing a spring held in the trigger adjusts trigger pressure needed to complete the second stage trigger pull after the contact face on the disconnect lever contacts the hammer tang. A spring operably connected with the trigger and the torsion spring adjustment plate adjustable by the user allows a user to adjust first stage pressure on the trigger necessary to move the disconnect lever contact face against the hammer tang.
