The Crimson Trace LG-404 is most popular 1911 laser sight model for Officer's, Compact and Defender variants. This Pro-Custom model features a stylish burlwood pattern. 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-404 features instinctive activation. This means that the laser sight automatically springs to life when the weapon is held in a natural firing grip.
