DetailsThis is the premier trigger kit for the M&P, taking a standard striker-fired trigger pull and elevating it to a trigger as close to that in a single-action 1911 that you can get in a polymer duty gun. This patented kit is engineered to provide the M&P pistol owner with a smooth, consistent trigger pull with the advantages of shorter over-travel and shortened trigger reset. Using a combination of the Apex springs and factory sear and trigger return springs allows the user to set the trigger pull weight within a range suitable for duty/carry down to a weight desired for competition. This drop-in trigger kit will: - Reduce trigger pull weight to approx. 3 to 4 lbs. - Reduce overall trigger travel by approximately 40% - Reduce trigger pre-travel, over-travel and reset distance - Smooth the uptake and reset - Deliver a crisp trigger break - Maintain factory safety values with a center mounted pivoting safety - Direct drop-in replacement parts, not fitting required For Use In These GunsFor use in all Smith & Wesson original centerfire M&P models. NOTE: Requires use of sear housing block designed for large size sear plunger and spring (current production as of June 2011). Does Not Fit These GunsNot for use in the M&P M2.0 models, any M&P Shield models, or .22 caliber M&P models. What's Included1 ea. Flat-Faced Forward Set Trigger 1 ea. 3-Dot Forward Set Sear 1 ea.
