What It Does
Coupled with our Apex Fully Machined Sear and Apex Ultimate Striker Block, the Apex M&P Competition Spring Kit will further reduce trigger weight by approximately 2.0 lbs. (based on a starting trigger pull weight of 7.0 to 8.0 lbs.). Whether your game is IDPA, USPSA or Steel Challenge, our Competition Spring Kit will withstand the rigors of high speed competition. Our competition striker spring and trigger return spring are shot peened to extend service life.

This kit is recommended for competition use only -– NOT FOR DUTY/CARRY OR SELF-DEFENSE APPLICATIONS.

Expected Results
– Reduces trigger pull weight in your M&P pistols

1 ea. Apex Competition Striker Spring

1 ea. Apex Competition Trigger Return Spring

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.
