The Crimson Trace LG-489 Laserguard is an integrated red laser sight designed specifically to match the contours of the Smith & Wesson M&P Shield platform in 9mm and .40 S&W.

The unit is user-installable with no gunsmithing required and includes windage and elevation adjustments for on-the-gun zeroing. This Laserguard is finished in black polymer with a rubber overmold activation pad and is not compatible with Shield EZ or Shield Plus models.
