The Apex Action Enhancement Aluminum Trigger & Duty/Carry Kit (brand part no. 100-079) is built for Smith & Wesson M&P pistols chambered in 9mm or .40 S&W. Apex Tactical Specialties replaces the factory trigger, sear, and safety plunger as a set, which delivers a smooth, crisp trigger pull suited to duty and everyday-carry use. Because it swaps all three components together, the kit maintains the factory safety mechanisms while improving trigger feel over the stock M&P pull. It is built specifically for the 9/40 frame size and is not compatible with other M&P chamberings.
