This kit is a combination of the apex duty/carry kit for the m&p shield and the apex action enhancement red trigger for the m&p shield.The action enhancement trigger 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.
