The Lever Action Trigger for the S&W 1854 Series is easy to install and features a nonadjustable, factory-set pull weight of 2.5 – 3 pounds. The trigger showcases the exceptionally crisp and smooth feel one has come to expect from a Timney Trigger and will aid shooters in their quest for accuracy. 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.
