Apex Tactical



What it does:
  The APEX Duty/Carry Action Enhancement Kit (DCAEK) was designed to provide the M&P (9 mm, .357 Sig & .40 only) pistol owner a smooth, consistent 5 - 5.5 lb 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 engineered to be drop-in and should not require further gunsmithing (however, armorer or gunsmith installation is recommended).
