The apex action enhancement trigger directly replaces the factory hinged trigger with a solid body polymer trigger and a center-mounted pivoting safety.The rounded face of the trigger provides a smooth comfortable surface for the shooter's finger while firing.The trigger also reduces pre-travel and over-travel from the factory trigger.The apex duty/carry kit is engineered to provide the m&p m2.0 (and m&p 45) pistol owner with a smooth, consistent 5.0 to 5.5 lbs.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.Finish: BlackModel: Action EnhancementMaterial: Polymer
