Action Enhancement Trigger Kit for M&P

Description

This trigger kit is built for shooters who demand consistent, repeatable performance from their M&P pistol. Whether you are running drills on the range, competing in a match, or carrying a duty rig, the goal is the same: a clean break and a fast reset. This drop-in system delivers that without compromising the safety features you rely on.

The kit reduces your trigger pull weight by approximately one pound, settling into a reliable 5.0 to 5.5 lb. range. This is a purposeful weight—light enough to minimize muzzle disturbance during the break, but heavy enough to stay within the safety margins of a serious service pistol. You get a smooth uptake with a crisp, defined break and a shortened reset that gets you back on target faster.

Pre-travel and over-travel are both reduced by roughly 20%. This means less wasted motion in the trigger cycle. The shorter over-travel helps prevent over-rotating the trigger after the shot breaks, which can pull the sight picture off target. The center-mounted pivoting safety maintains all factory safety values, so you are not sacrificing reliability for performance.

Key performance benefits:

• Pull weight: 5.0 to 5.5 lbs. (reduced by approx. 1 lb. from factory)
• Travel reduction: Pre-travel and over-travel cut by approx. 20%
• Trigger feel: Smooth uptake, crisp break, short positive reset
• Safety: Factory center-mounted pivoting safety retained
• Installation: Direct drop-in replacement parts. No fitting or gunsmithing required.

Compatibility and fitment notes:

• Designed for Smith & Wesson M&P pistols in 9mm or .40 S&W.
• This kit requires the larger 1/8 inch sear spring and plunger setup.
• If your M&P currently uses the older 1/16 inch diameter sear plunger and spring, you must upgrade to the new style sear housing block before installing this product. All function and reliability testing was performed with the 1/8 inch sear plunger and spring. We cannot guarantee proper function without the appropriate size sear components.
• Modern sear housing blocks are available through Brownells and other online firearms parts retailers.

This is a straightforward upgrade for shooters who want a sharper, more predictable trigger without turning their pistol into a range-only piece. The weight and reset characteristics are tuned for high-volume use, competition stages, and duty applications where split
