Easy-to-install part eliminates trigger overtravel, for faster reset and faster, steadier follow-up shots than with a factory-stock pistol. Helps you keep on the target by reducing the time the sights can “wander” between rapid fire shots. Redesigned polymer trigger housing with steel ejector is a direct replacement for the factory housing and can be installed and removed at will. Recommended for competition use only.
