Action Enhancement Trigger Kit for M&P

Description

For M&P owners looking to improve their trigger without compromising reliability or safety, this Action Enhancement Trigger Kit delivers a refined shooting experience at a practical price point of $110. Designed specifically for Smith & Wesson M&P pistols in 9mm or .40 S&W, this drop-in kit reduces trigger pull weight to a consistent 5.0 to 5.5 pounds—an ideal range for a service-grade pistol that balances precision with everyday carry dependability.

The kit works by replacing key internal components to shorten both pre-travel and over-travel by approximately 20%, resulting in a noticeably crisper break and a faster reset. You get a smooth uptake with no gritty feel, and the reset is short and tactile, helping you stay on target for follow-up shots. All of this is achieved while maintaining factory safety values thanks to the center-mounted pivoting safety design.

Key specifications and benefits:

• Pull weight reduction: Lowers trigger pull by roughly 1 pound from factory weight, settling into the 5.0–5.5 lb. range—suitable for defensive use or competition.
• Travel reduction: Pre-travel and over-travel are cut by about 20%, giving you a shorter, more efficient trigger stroke.
• Feel: Smooth uptake and reset with a clean, predictable break. No stacking or creep.
• Drop-in installation: All parts are direct replacements with no fitting required. You can install this kit at home with basic tools.
• Compatibility: Works with M&P models chambered in 9mm or .40 S&W. The kit is designed for the larger 1/8-inch sear spring and plunger setup.

Important fitment note: This kit requires the use of a 1/8-inch diameter sear plunger and spring. If your M&P has the older 1/16-inch sear plunger and spring, you will need to upgrade to a newer sear housing block before installing this kit. All function and reliability testing was performed with the 1/8-inch setup, so proper operation cannot be guaranteed with the smaller components. Modern sear housing blocks are available through Brownells and other online firearms parts retailers.

This trigger kit is a practical upgrade for the M&P owner who wants a better trigger feel without sending the pistol to a gunsmith or compromising the safety features that matter. It keeps your pistol California-compliant and street-ready while giving you a more predictable, faster trigger that supports accurate shooting.
