Machined to fit seamlessly while bringing both artistry and rugged engineering to John Browning's classic 1911 design, Maser Series Lasergrips are sure to impress. Featuring ergonomic and aggressively durable G10 side panels with a rubber overmolded activation button; these are the ultimate laser sights. Standard to Crimson Trace Lasergrips, the LG-902 features instinctive activation. This means that the laser sight automatically springs to life when the weapon is held in a natural firing grip. Good for you. Bad for your target.
