Crimson Trace Laserguard LG-459 - S&W Shield EZ - Red Laser

The Crimson Trace LG-459 Laserguard is a user-installable red laser sight for the Smith & Wesson M&P 9 EZ, M&P 380 EZ, and M&P 22 Compact — 5mW red laser with front Instinctive Activation, factory sighted at 50 feet with user-adjustable windage and elevation, and 4 hours of battery life from a single included 1/3N lithium battery.

The Crimson Trace LG-459 (01-9870-1) is a drop-on Laserguard red laser sight for the S&W M&P 9 EZ, M&P 380 EZ, and M&P 22 Compact. Features a 5mW red laser (maximum legal output), front-mounted Instinctive Activation button, user-adjustable windage and elevation with included tool, and 4-hour battery life. Power: single 1/3N lithium battery included. Factory sighted at 50 feet. User-installed — no gunsmithing required.

Instinctive Activation is Crimson Trace's design principle that the laser should activate the moment the shooter establishes a firing grip — the LG-459's front activation button is positioned where the support hand's fingers naturally contact the front of the grip, so the laser engages automatically as the shooter wraps their hand around the pistol without requiring a separate button press or mode change. This means the laser is on when the shooter needs it and off when the pistol is holstered, with no manual on/off management required during a defensive draw. At 5mW, the LG-459 outputs the maximum red laser power permitted under FDA and federal regulations — the brightest legal red laser available, providing the longest effective visible range in ambient light conditions that lower-powered alternatives cannot match. Factory sighting at 50 feet provides a useful zero for defensive distances, and the included adjustment tool allows windage and elevation correction to match the shooter's specific zero distance or correct for any point-of-impact offset. The drop-on installation requires no modification to the firearm and no gunsmithing tools.

Instinctive Activation engages the laser on a natural firing grip — no separate button press required during a defensive draw. 5mW output is the maximum legal red laser power for maximum visible range in ambient light. Factory sighted at 50 feet with user windage and elevation adjustment. Drop-on fit, no gunsmithing.
