What It Does
The Apex M&P Competition Action Enhancement Kit was designed for the action shooting sports competitor. Our drop in kit will reduce trigger weight by approximately 4.0 lbs. (based on a starting trigger pull weight of 7.0 to 8.0 lbs.) Whether the game is IDPA, USPSA or Steel Challenge, our Competition Action Enhancement Kit will withstand the rigors of high speed competition. Our competition striker spring and trigger return spring are shot peened to extend service life. The kit itself is engineered to be drop-in and should not require further gunsmithing (however, armorer or gunsmith installation is recommended). The M&P Competition Action Enhancement Kit is perfect for use with the M&P already equipped with the Apex Polymer or Aluminum Action Enhancement Trigger.

Installation Resources

You may need to make an adjustment to the trigger bar loop for proper function. If you should need to tune your trigger bar, please follow the instructions on the following video: Trigger Bar Loop Adjustment Video

*For those with a CA, MA, or other 10+ lb required trigger pull weight; due to heavier average spring rates, results are likely to be more significant, with a reduction of 6-7 lbs.

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.
