Crimson Trace Front Activation 1911 Compact Red Lasergrips - Black - The flagship LG-404 is our most popular 1911 laser sight model for Officer's, Compact and Defender variants. Featuring 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. This product is not compatible with ambidextrous safety levers. We stock shortened ambi-safeties from Wilson Combat in BLACK and STAINLESS. Gunsmith installation is required.
