The Apex Action Enhancement Trigger & Duty/Carry Kit for the Smith & Wesson M&P Shield is a drop-in upgrade designed specifically for the Shield in 9mm Luger and .40 S&W configurations. The kit replaces the factory hinged trigger with a solid aluminum trigger body that reduces pre-travel and over-travel by approximately 20% while maintaining factory safety values through a center-mounted pivoting safety. The included Duty/Carry Kit smooths and lightens the trigger pull by approximately 2 lbs (based on variations in factory tolerances) and provides a more detectable reset. Armorer or gunsmith installation of the Ultimate Striker Block (USB) into the Shield slide is strongly recommended.
