Apex Shield Action Enhancement Trigger & Duty Carry Kit for M&P Shield 9/40

#html-body [data-pb-style=IYAPHWQ]{justify-content:flex-start;display:flex;flex-direction:column;background-position:left top;background-size:cover;background-repeat:no-repeat;background-attachment:scroll}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.
