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.
