The Colt Government 1911 A1 is the classic configuration of the legendary Colt 1911 handgun carried by U.S. troops in several wars. The Colt Government 1911 A1 Semi-Automatic Pistol in .22 LR is manufactured exclusively by Walther under license from Colt. Walther's 1911 A1 Rail Gun is an authentic Colt Government model with all-steel lock work and a Commander-style hammer. The Rail Gun has fully-functioning thumb and grip safeties and an extended beavertail grip safety. The front and rear slide serrations are both attractive and functional. The picatinny mounting rail and threaded muzzle make the Rail Gun endlessly adaptable. Additional features include low-mount 3-dot combat sights, a skeletonized trigger, checkered rubber grip panels, and an authentic half-cock mechanism.
