This is a Apex Tactical Specialties Trigger known as the Action Enhancement Trigger, model 100-161.
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.
Features:
Reduces trigger pull by approximately 2 lbs.
Smooth uptake and reset, Reduces pre-travel
