The M2.0 Shield Action Enhancement Trigger Kit directly replaces the factory hinged trigger with a black 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.Kit Includes:Black Anodized Aluminum Shield Action Enhancement TriggerShield Duty/Carry Kit (Fully machined 1-Dot Sear, Ultimate Striker Block, Striker Block Spring, Sear Spring (1/8"), 4 lb Rated Trigger Return Spring, Trigger Return Spring Installation Shield Slave Pin) FeaturesReduces trigger pull by approximately 2lbs.Center mounted pivoting safety maintains factory safety valuesSmooth uptake and resetReduces pre-travelReduces over-travelReduces reset
