Designed to work in any Smith & Wesson M&P model pistol in a centerfire caliber, the Apex Flat-Faced Forward Set Sear & Trigger Kit reduces trigger pre-travel and over-travel, while allowing the shooter to position their finger at an increased leverage point lower on the trigger face to take advantage of lower trigger pull weights. - Trigger pull weight between the 3lb (silver spring) and 4lb (green spring) mark (Dependent on trigger return spring installed) - Smooth uptake and reset - Reduced trigger pre-travel and over travel to produce a feel similar to a single action fire control system - Overall reduction in trigger travel is approximately 50% - Reduced reset - Center mounted pivoting safety maintains factory safety values NOTE: As of May 15th, 2018, this trigger kit is legal for use in USPSA's Production Division (please see Appendix D4, section 21.6, of the USPSA)
