The LG-404 P16 is our most popular 1911 laser sight model for Officer’s, Compact and Defender 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-404 features instinctive activation. This means that the laser sight automatically springs to life when the weapon is held in a natural firing grip. Fits Colt (Officer’s and Defender), Kimber (compact, ultra-carry and ultra-elite), Para-Ordnance (compact, single-stack), Springfield Armory (compact and ultra-compact) Wilson Combat and most other 1911’s with grip screws measuring 2-11/16" apart.
