Apex Tactical Action Enhancement Trigger Kit for Smith & Wesson M&P 9mm / .40 S&W Pistols

The Apex Tactical® Action Enhancement Trigger Kit for Smith & Wesson® M&P® 9mm / .40 S&W Pistols reduces trigger pull weight by about 1-5lbs. and features a smooth uptake and reset with a crisp trigger break. This kit maintains factory safety values with a center mounted pivoting safety and is a direct drop-in replacement. Even better, this kit reduces pre-travel and overt-travel by about 20%. Not for use in the original M&P 45, the M&P M2.0, or any model Shield.

This kit REQUIRES the use of the larger 1/8 inch sear spring and plunger set up. If your M&P has a 1/16th inch diameter sear plunger and spring, Apex Tactical strongly advises you upgrade to a new style sear housing block before installing this product. All function and reliability testing was done with a 1/8 inch sear plunger and spring, therefore they cannot guarantee proper function without the appropriate size sear plunger and spring. Modern sear housing blocks can be found on Brownells.com and other online firearms product retailers.
