The APEX Shield Carry Kit Kit (SCK) was designed to provide the M&P Shield pistol owner a smooth, consistent 5 - 5.5 lb trigger pull with the advantages of shorter over-travel and more detectable 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 of the USB into the Shield slide is strongly recommended**.
Trigger Pull in the mid 5lb range
Smooth Uptake and reset
Reduced over travel
Applicable to what guns:
Smith & Wesson Shield only.
Both 9 and 40 Caliber.
**The Shield sight removal in order to install the USB Kit is extremely difficult. Removal requires delicate precision so as not to damage the sights or slide. We highly recommend having a competent gunsmith perform this task.
