The Shield Action Enhancement Trigger Kit directly replaces the factory hinged trigger with a red anodized, 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 center mounted pivoting safety bar prevents unintended operation by creating a trigger block that will not disengage unless the shooter places their finger directly on the trigger face.
The Apex Shield 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. 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 into the Shield slide is strongly recommended.
The Shield Action Enhancement Trigger Only is perfect for use with the M&P Shield already equipped with the apex Shield Duty/Carry Kit. Works with all Smith & Wesson M&P Shield pistols in 9mm and .40 calibers, does not work in the Shield 45.
