Apex Tactical 100051 Action Enhancement Duty/Carry Kit Drop-in Trigger with 1-2 lbs Draw Weight, for S&W M&P Shield
This kit is a combination of the Apex Duty/Carry Kit for the M&P Shield (9/40 only) and the Apex Action Enhancement Trigger for the M&P Shield (9/40 only). 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 was designed to provide the M&P Shield pistol owner a smooth, consistent trigger pull that is approximately 2 lbs lighter (based on variations in factory tolerances) with the advantages of shorter over-travel and more detectable trigger reset. However, armorer or gunsmith installation of the Ultimate Striker Block (USB) into the Shield slide is strongly recommended.
