All components of this complete trigger assembly are wire EDM cut to ensure all parts hold the tightest tolerances. The trigger shoe, sear, and hammer strut are cut from A2 tool steel and are hardened for remarkable wear resistance. The hammer is cut from S7 tool steel that is hardened for shock-resistance and long-lasting strength.
