The Apex Polymer Forward Set Trigger Kit reduces pre-travel and over travel. The kit comes with two different trigger return springs allowing the user to choose between 4lbs for competition use and 5.5lbs for duty/carry use.
Works with all Smith & Wesson M&P Pistols (excluding M&P M2.0) in all centerfire calibers and configurations. Does NOT function in the M&P M2.0, M&P Shield, BodyGuard, 22 or 22 Compact pistols.
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, we strongly advise 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 we cannot guarantee proper function without the appropriate size sear plunger and spring. Modern sear housing blocks can be found on MidwayUSA!
