Action Enhancement Trigger Kit for M&P

Description

For M&P owners who carry daily or shoot matches on the weekend, the trigger is the primary interface between you and your pistol. The Action Enhancement Trigger Kit delivers a practical upgrade that sharpens your shooting without compromising safety or reliability. Priced at $110, this drop-in kit is designed for M&P pistols in 9mm or .40 S&W, providing a consistent pull weight between 5.0 and 5.5 pounds—right in the sweet spot for a service-grade defensive handgun.

What you get is a smoother, more predictable trigger that helps you place shots faster and more accurately. The kit reduces pre-travel and over-travel by roughly 20%, meaning less wasted motion between shots. The reset is noticeably shorter, so you can stay on target for follow-ups without consciously mashing the trigger forward. The break is crisp, not gritty, and the uptake stays smooth throughout the pull.

All components are direct drop-in replacements. No filing, no fitting, no trips to a gunsmith. The kit includes a center-mounted pivoting safety that maintains factory safety values, so you can trust it in a holster day in and day out. Expect the pull weight to drop by about one pound from stock—enough to improve accuracy without going too light for defensive use.

Important fitment note: This kit requires the larger 1/8-inch sear spring and plunger setup. If your M&P has the older 1/16-inch diameter sear plunger and spring, you will need to upgrade to a modern sear housing block before installation. All factory function and reliability testing was done with the 1/8-inch components, so proper function cannot be guaranteed without them. Modern sear housing blocks are available at Brownells.com and other online retailers.
