Dropping this kit into your Smith & Wesson M&P will set the trigger break point farther forward than the factory trigger assembly as well as significantly reduce the uptake and over travel. It produces a trigger pull very similar to that of a 1911 but in a polymer frame striker-fired pistol. The Forward Set Trigger body is machined from aircraft-grade aluminum and black hard anodized to last a lifetime. The smooth-faced trigger comes assembled with a center pivoting safety. The Forward Set Sear & Trigger Kit boasts a smooth trigger pull throughout the break. The kit comes with two (2) trigger return springs; one designed to produce approximately a 4.0 lbs trigger pull (silver spring) and one to produce a 5.0 lbs trigger pull (green spring). These two options give the end-user the ability to customize their trigger pull for their specific needs.
