The Apex Duty/Carry Action Enhancement Kit is engineered to provide the M&P pistol owner a smooth, consistent 5.0 to 5.5 lbs. trigger pull with the advantages of shorter over-travel and shortened trigger reset. All of the components work together to provide a pull weight within the acceptable range for a top end, service pistol. The kit itself is designed to be drop-in and should not require further gunsmithing, however, armorer or gunsmith installation is recommended.
– Reduces over-travel
– Smooths trigger pull
– Keeps pistol at a safe 5-5.5 lb trigger pull weight for Duty/Carry applications Installation Resources

*This kit REQUIRES the use of the larger 1/8 inch sear spring and plunger set up. If your M&P has a 1/16th inch diameter sear plunger and spring, we strongly advise you upgrade to a new style sear housing block before installing this product. All function and reliability testing was done with a 1/8 inch sear plunger and spring, therefore we cannot guarantee proper function without the appropriate size sear plunger and spring. Modern sear housing blocks can be found on Brownells.com and other online firearms product retailers.
