IMMEDIATE. DECISIVE. ADVANTAGE. Lasergrips remain the most decisive tactical advantage for handguns, changing the way gun owners approach personal protection. They offer what no other handgun accessory can: immediate targeting with a bright red or green laser beam when you hold your gun in a natural firing grip. This innovation, Instinctive Activation, saves precious time when seconds count. Lasergrips are compatible with your favorite holster, feature a master on/off switch, provide 2 (green) to 4 (red) hours of battery life, are easily user-installed with zero modification to your firearm and are completely user-adjustable for windage and elevation. Crimson Trace also extends one free set of batteries a year for life when you register you Crimson Trace product on the manufacturers website. Note: Crimson Trace Lasergrips are factory-sighted to approximate point-of-impact at 50-feet.
