Crimson Trace® takes seriously the life-saving potential and crime-deterring influence offered by laser gun-sight technology. The Revolver Lasergrips® are available with the same super-quick and efficient sighting principals as the original Lasergrips with the added comfort and recoil control of soft rubber overmolded construction or smooth, snag-free hard polymer that's well-suited for self-defense. LG-350 models feature the Crimson Trace ShockStop™ system that combines soft, vibration-reducing material with a cushioned grip that reduces felt recoil. All models have more than four hours of run time and a battery shelf life of five years. Range is up to 30 ft. in broad daylight. Manufacturer's three-year warranty.
