The LG-489G is a seamlessly integrated green laser sight for Smith & Wesson's M&P Shield concealed carry pistol. This 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-489G is also fully adjustable for windage and elevation. Features a powerful green laser diode for improved laser targeting in all lighting conditions.
