What It Does
This kit is a combination of the Apex Duty/Carry Kit for the M&P Shield 45 and the Apex Action Enhancement Trigger for the M&P Shield 45. The Trigger Kit directly replaces the factory hinged trigger with a solid aluminum trigger body which reduces pre-travel and over-travel by approximately 20%. It features a smooth face with a center mounted pivoting safety that maintains factory safety values.

The Apex Duty/Carry Kit for the Shield 45 was designed to provide the pistol owner a smooth, consistent trigger pull that is approximately in the range of 5.0 to 5.5 lbs. with the advantages of shorter over-travel and more detectable trigger reset.


Expected Results
– Reduces trigger pull by approximately 2 lbs.
– Smooth uptake and reset
– Reduces pre-travel
– Reduces over-travel
– Reduced reset
– Center mounted pivoting safety maintains factory safety values

**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.

Apex Tactical Specialties offers this service for $35.00 (labor only), plus $17.50 return shipping. If you decide to have Apex perform this service, mail in the slide portion ONLY of your Shield. You may mail it directly to us via USPS, UPS, or FedEx. Please refer to our Services menu for more information.
