The Crimson Trace LG-401 is the most popular 1911 laser sight model for Government and Commander variants. This Pro-Custom model features a stylish Walnut finish. With rugged polymer side panels and a rubber overmold activation button, these are the recommended Lasergrips for most 1911 shooters. Standard to Crimson Trace Lasergrips, the LG-401 features instinctive activation. This means that the laser sight automatically springs to life when the weapon is held in a natural firing grip.
