Maser Series Lasergrips fit seamlessly while bringing both artistry and rugged engineering to the 1911 design. Fully compatible with ambidextrous safeties, this Master Series Lasergrip fits either full-sized Government/Commander or the compact Defender/Officer models and feature ergonomic and aggressively durable G10 side panels with a black and gray finish and rubber overmolded activation button. Standard to Crimson Trace, Lasergrips feature instinctive activation so the laser sight automatically springs to life when the weapon is held in a natural firing grip.
