The Colt Ace was a firearm designed to allow inexpensive and low-recoil practice while maintaining the feel of the military Model 1911 pistol. Accordingly, military, police, or layman shooters could shoot the Ace without the recoil and expense of the 1911, but with similar ergonomics and sight picture. The barrels of these guns are constructed with a hinged floating rear chamber that amplifies the recoil, cycling the heavy slide. The Ace is a conventional blow-back operated semi-automatic that outwardly resembles the gun adopted by Uncle Sam in 1911, but with the swinging link and locking lugs of the .45 replaced by a barrel pinned solidly into the frame by the slide stop. Other modifications included a 1/4" shorter slide and barrel, a unique rim-fire firing pin and stop, ejector, and a stack of shock-absorbing washers under the barrel that limit slide travel, necessitating relocation of the slide stop notch to suit the new .22-length action. This pistol features a Pachmayr wooden grips, manual thumb and grip safeties, and adjustable target sights and comes with four 10-round magazines and the original factory box. Its grips, metal, and bore are all in very good condition.
