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 rosewood 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.
