The EVO ELITE is Smoother, Lighter, Shorter and eliminates trigger Over-travel! These attributes give you the fastest most accurate first shot hit advantage of any self-defense Glock style trigger. The EVO ELITE fixes the Glock bump or glitch, this is the pre-travel resistance you feel and must overcome when the trigger bar bumps into the connector. This bump causes you to apply excessive force and will move the pistol off target.
