The Colt Combat Unit 1911 Semi-Auto Pistol with Rail was built with the guidance and assistance of US Special Forces trainers. This is a Colt that's built for gunfighters. Custom G10 grips and 25 LPI (Lines Per Inch) checkering make this gun lock in place in your hand. The upswept-beavertail grip safety and extended, ambidextrous thumb safety feel great. Colt's series 80 firing system and National Match Barrel keep things safe and accurate. Front and rear cocking serrations on the slide give you options for manipulating the slide, which is also topped off with Novak sights. Faster reloads come easy with the attached, bevelled magwell. The Combat unit also features an integral frame rail for attaching a light or laser device. The Combat Unit is topped off with the ion-bonded, DLC finish that is tough as nails. This Colt Combat Unit is so well-rounded and encompasses everything you need in a handgun to shoot incredibly well. The rest is up to you. 25 LPI checkering on front strap G10 grips Ion bond finish Extended thumb safety Extended beavertail safety Match-grade barrel Novak sights Beverled magwell Integral Picatinny rail
