Crimson trace green laserguard for s&w m&p full size - Crimson Trace Green Laserguard for S&W M&P Full Size and Compact

Fit my .40Cal S&W M&P Full Size pistol perfectly and matched the color of the black pistol perfectly. Simple to install, no modifications, comes with hex keys to mount on rail and adjust the laser sighting. Fit my nylon holsters without modifying. I tried other lasers before spending the money for this one. I wished I hadn't. All the others would catch on the holsters or my pocket when drawing the weapon and the on/off switches were clumsy to use or would turn on inside the holster and run the battery down. This one only turns on when you grasp the pistol grip firmly and properly. Highly recommended. The green laser works much better during the day than a red laser.
