APEX TACTICAL SPECIALTIES 100171 Action Enhancement Duty/Carry Kit S&W M&P Shield 2.0 9/40 Enhancement Drop-in

This kit is a combination of the Apex Duty/Carry Kit for the M&P Shield 2.0 and the Apex Action Enhancement Trigger for the M&P Shield 2.0. 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 2.0 pistol owner a smooth, consistent trigger pull that is approximately 1-2 lbs lighter (based on variations in factory tolerances and the combination of springs used) 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.
