Under $100 and well worth it...

The Apex Duty/Carry Kit for the M&P Shield was designed to provide the 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. All of the components work together to provide a pull weight within the acceptable range for a top end, service pistol. The kit itself is engineered to be drop-in and should not require further gunsmithing. However, armorer or gunsmith installation of the Ultimate Striker Block (USB) into the Shield slide is strongly recommended**.

Expected Results
– Reduces trigger pull by approximately 2 lbs.
– Smooth uptake and reset
– Reduces reset length
– Reduces over-travel
