The LG-489 is a seamlessly integrated 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 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-489 is also fully adjustable for windage and elevation. Gun not included.
