Colt 70

The Colt 70, often referring to the Colt Government Model 1911 Series 70, represents a specific generation of the classic Colt 1911 pistol. Produced from approximately 1970 to 1983, the Series 70 is distinguished primarily by its "collet" style barrel bushing, designed to improve accuracy. This bushing has four "fingers" or collets that center the barrel within the slide.

Key features that differentiate the Series 70 from earlier and later models include the aforementioned collet bushing, as well as changes in the roll marks on the slide. While earlier models retained the high polish blue or nickel finish, the Series 70 also saw the introduction of less expensive, more utilitarian finishes.

The Series 70 remains a popular choice among 1911 enthusiasts and collectors. While some prefer the original Series 70 for its perceived accuracy advantage, others find the collet bushing prone to breakage and prefer other 1911 designs. The pistol's enduring legacy stems from its connection to the classic 1911 design and its role in the evolution of the platform. It is often regarded as a desirable example of the 1911 pistol lineage.
