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 reduced reset. The kit includes:
* APEX Hard Sear (9 mm, .357 Sig & .40 series) - NOT FOR .45 ACP
* APEX M&P Ultimate Striker Block Kit (USB kit)
* APEX M&P Increased Rate Sear Spring** & Trigger Return Spring (aluminum slave pin included)
**Two sear springs of different sizes are included with kit. Use the one that fits your M&P.
***This kit will reduce most of the over travel in the M&P trigger system but will not reduce pre-travel/up-take. To reduce pre-travel/up-take, see our Forward Set Sear and Trigger Kit.
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 require NO further gunsmithing (however, armorer or gunsmith installation is recommended).
