Apex Tactical M&P 9/40 Duty/Carry Action Enhancement Kit


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).


Parts included:

  1. APEX Fully Machined Sear
  2. APEX M&P Ultimate Striker Block Kit (USB kit)  
  3. Ultimate Striker Block
  4. USB Spring
  5. Talon Tactical Tool  
  6. Duty Carry Spring Set
  7. 1/8" Sear Spring*
  8. Trigger Return Spring
  9. Aluminum slave pin 


*This kit no longer contains a Small 1/16" sear plunger spring.  If your gun has the 1/16" sear spring, we recommend purchasing a new sear housing block, if you are unable to obtain a new sear housing block, we recommend the use of the factory sear spring..


Expected results:

Shortens over-travel.

Smooth trigger pull.

Keeps pistol at a safe 5-5.5 lb trigger pull weight for Duty/Carry applications.
