Colt introduced the Series 70 in 1970, adding the Accurizor collet bushing to enhance out-of-the-box accuracy without altering the classic 1911 profile. This example retains that four-finger bushing, a feature often removed on later guns.
The pistol wears Colt’s signature Royal Blue bluing on both the carbon-steel slide and frame, a finish known for its depth and gloss. The finish on this 1972 gun remains attractive, with wear noted only in specific areas detailed above.
Smooth walnut grip panels with silver Colt medallions lend period-correct aesthetics and a secure, comfortable grasp. Standard fixed sights, a spur hammer, thumb safety, and grip safety maintain the traditional Government Model configuration.
As a full-size Government Model, it sports a 5-inch barrel, single-action trigger, and 7+1 capacity. The clean, sharp bore indicates minimal use and promises strong performance on the range or as part of a collection.
