Description
The Action Enhancement Trigger Kit for M&P is a drop-in upgrade engineered to give your Smith & Wesson M&P (9mm or .40 S&W) a smooth, consistent 5.0 to 5.5 lb trigger pull. This kit reduces pre-travel and over-travel by about 20%, shortens reset, and delivers a crisp break—all while maintaining factory safety values. It’s a straightforward way to improve accuracy and speed for self-defense without compromising reliability.

Key Features
- Reduced Trigger Pull Weight: Cuts pull by about 1 lb to the 5.0–5.5 lb range. Why it matters: This eliminates the heavy, gritty factory pull without dropping below the safe threshold for a carry pistol—keeping you accurate under stress.
- Shortened Pre-Travel and Over-Travel: Reduces both by roughly 20%. Why it matters: Less wasted movement means faster follow-up shots and tighter shot groups, especially during rapid fire in a defensive scenario.
- Shortened Trigger Reset: Delivers a tactile, audible reset that’s noticeably shorter than stock. Why it matters: You’ll shoot faster because you can feel exactly when the trigger is ready to fire again—no guesswork.
- Crisp Trigger Break: Provides a clean, glass-like break with no creep. Why it matters: A predictable break prevents yanking the shot off target, giving you confidence in high-pressure situations.
- Drop-In Installation: All components fit directly into your M&P frame without fitting or gunsmithing. Why it matters: You can install it yourself in minutes, saving time and money over a professional trigger job.
Who It’s For
This kit is built for concealed carriers and home defenders who rely on their M&P for personal protection. If you want a trigger that’s lighter and smoother than stock but still safe for daily carry—not a race gun pull—this fits the bill. It’s also ideal for shooters who want more accuracy from their service pistol without voiding reliability.
Pros and Cons
- Pros: Smooth, consistent pull; short reset; easy drop-in install; maintains factory safety; works with M2.0 and Shield variants.
- Cons: Pull weight is fixed at 5.0–5.5 lbs—not adjustable. If you prefer a lighter competition trigger, this isn’t it. Per Smith & Wesson specs, this kit is designed for service use, not target shooting.
