Introducing the Colt Government 1911 Chambered in .22 L.R.
Now you can continue to shoot economically with a
Colt 1911 chambered in .22 long rifle. The Colt Government 1911 .22 L.R. is a new, licensed reproduction available in three rimfire variants-Government models 1911, 1911 Rail Gun, and 1911 Gold Cup. All three guns are dedicated .22 L.R., 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 after-market accessories. Ask your local firearm dealer about the
Colt 1911 .22 sold by Umarex USA and feed the need to shoot.
