Apex's curved forward set trigger kit is engineered to provide the m&p m2.0 pistol owner with a smooth, consistent trigger pull with the advantages of shorter over-travel and shortened trigger reset.All of the components work together to provide a pull weight within the acceptable range for a top end, service pistol.The kit itself is designed to be drop-in and should not require further gunsmithing, however, armorer or gunsmith installation is recommended.It is compatible with smith & wesson m&p m2.0 pistols in 9mm,.40s&w and.45acp calibers.It does not function in the original m&p or m&p shield models.The kit includes: black anodized curved forward set trigger, apex forward set sear actuator, apex fully machined 2-dot sear, ultimate striker block kit (striker block, spring and talon tactical tool), and forward set spring kit for m2.0: heavy sear spring (purple), duty/carry sear spring (silver), heavy trigger return spring (green), duty/carry trigger return spring (silver) and polymer slave pin for 11 total pieces in the package.Finish: Black AnodizedModel: Curved Forward SetMaterial: PolymerHand: Right
