The Colt 1911 Combat Unit Government Model Rail Gun is a single-action semi-automatic pistol chambered in .45 ACP, developed in collaboration with tactical trainers to function as a duty-ready tactical firearm. This handgun incorporates a 5-inch stainless steel National Match barrel and features a rugged stainless steel slide and frame treated with a matte black IonBond DLC finish for maximum wear and corrosion resistance. It utilizes Colt’s Series 80 firing pin safety system to ensure drop safety and is built with an integrated M1913 Picatinny accessory rail for weapon lights, an undercut trigger guard, an extended magwell, and 25 lines-per-inch front strap checkering paired with gray scalloped G10 grips. The duty-focused configuration is completed by an ambidextrous extended thumb safety, an upswept beavertail grip safety, front and rear cocking serrations, and genuine low-profile Novak night sights. The standard single-stack magazine holds 8 rounds, providing an overall capacity of 8+1.
