Action Enhancement Trigger Kit for M&P

Description

Living on the Florida coast means your gear battles humidity, salt air, and sand every single day. That is why the Smith & Wesson M&P Action Enhancement Trigger Kit is built with corrosion-resistant components that stand up to the coastal environment, keeping your EDC reliable when you need it most. For the shooter who carries daily—whether at the range, on the boat, or around town—this drop-in trigger kit delivers a genuine performance upgrade without compromising safety or requiring a gunsmith.

The kit is engineered specifically for the M&P platform in 9mm or .40 S&W. It reduces your trigger pull weight by approximately one pound, bringing it into the 5.0 to 5.5 lbs. range. That is the sweet spot for a service pistol: light enough to improve accuracy during fast follow-up shots, yet heavy enough to maintain a positive, deliberate trigger press under stress. Pre-travel and over-travel are both reduced by about 20%, which means your finger spends less time moving and more time on target. The uptake is smooth, the break is crisp, and the reset is noticeably shorter—allowing you to stay in the fight without fighting the trigger.

Key benefits for your EDC:

• Shorter reset and over-travel – Get back on target faster with a trigger that returns to the ready position sooner. This matters in defensive drills and competition stages alike.
• Crisp, consistent break – No grit, no stacking. Just a clean wall and a predictable release, shot after shot.
• Factory safety values maintained – The center mounted pivoting safety keeps all original drop-safety and trigger-safety functions intact. You do not sacrifice reliability for performance.
• Corrosion-resistant finish – All components are treated to resist rust and oxidation, so your trigger stays smooth even after a day at the beach or a humid range session.
• True drop-in installation – No filing, no fitting, no special tools. Remove your factory trigger components and install the kit in minutes. This is a direct replacement for your stock parts.

Important fitment note: This kit requires the use of the larger 1/8-inch sear spring and plunger setup. If your M&P currently uses a 1/16-inch diameter sear plunger and spring, you must upgrade to a new-style sear housing block before installation. All reliability and function testing was performed with the 1/8-inch sear plunger and spring, so proper operation cannot be guaranteed without them. Modern sear housing blocks are available through Brownells and other major firearms parts retailers.
