The Laserguard is designed to match the unique design of the pistol, and features our patented Instinctive Activation - meaning the laser is activated when the gun is held in a natural firing grip. Quickly installed with no gunsmithing required, the LG-485G is also fully adjustable for windage and elevation. Features a powerful green laser diode for improved laser targeting in all lighting conditions. Fits Smith & Wesson M&P Shield .45 ACP.
