The dedicated .22 long rifle platform used for this Colt Government 1911 .22 Series is a licensed reproduction available in three rimfire variants-Government models 1911, 1911 Rail Gun, and 1911 Gold Cup. All models are in the popular 1911-A1 style. All three Colt Government rimfire models are dedicated .22 L.R.s, but they're engineered in true replica form with fully functioning thumb and grip safeties and the 1911's authentic half-cock mechanism. Grips and sights can be interchanged with a skeleton trigger, combat-style sights, beavertail grip safety, extended thumb safety, and a commander-style hammer.
