The Apex Tactical Action Enhancement Trigger & Duty/Carry Kit (brand part no. 100-051) combines Apex’s Duty/Carry Kit with its Action Enhancement Trigger for the S&W M&P Shield, 9mm and .40 S&W only. Apex Tactical Specialties replaces the factory hinged trigger with a solid aluminum trigger body that cuts pre-travel and over-travel by roughly 20%, adding a smooth face with a center-mounted pivoting safety that preserves the factory safety function. The Duty/Carry Kit lightens the pull by about 2 pounds versus factory tolerances, with shorter over-travel and a more detectable reset.
