The Colt Diamondback occupies an often-overlooked place in Colt’s storied line of “snake guns.” It is, nonetheless, an exceptional example of Colt production during a period when refinement, balance and mechanical precision defined the company’s double-action offerings.
Introduced in 1966, the Diamondback was a deluxe small-frame revolver that delivered target-grade features and unmistakable Colt styling in a more compact and approachable format than the Python. Built on Colt’s popular D-frame, the same platform used for the Detective Special, the Diamondback quickly earned a reputation as a revolver that handled as elegantly as it looked.
The Diamondback’s chambering may be part of what made it an overlooked gun. It wasn’t as powerful as the Anaconda in .44 Mag. or the Python’s .357 Mag. chambering. The Python, of course, could also .38 Special with ease. Whatever the reasoning may be, the original run of guns is no longer overlooked. They are, in fact, highly prized by discerning collectors.
The example in the February Collection bears serial number D89210. This indicates that it was manufactured in 1976. It wears a 4-inch vent-rib barrel, a configuration prized for its balance and versatility, and is finished in nickel. This gives the revolver a bright, refined appearance that highlights its crisp lines. The combination of a ventilated rib, full-length barrel underlug and fully adjustable rear sight paired with a serrated front blade gives the Diamondback a profile often described as a “scaled-down Python.” Without a doubt, that’s a comparison that speaks volumes about the Diamondback’s aesthetic appeal.
Lessor Known Snake
Mechanically, the Diamondback reflects Colt’s high standards during the company’s golden era of revolver production. The double-action system is smooth and deliberate. The single-action break is clean and predictable. Dependable and repeatable characteristics such as these made these revolvers favorites among target shooters and general revolver enthusiasts. The six-shot swing-out cylinder offers traditional Colt lockup and timing. Even better, the revolver’s proportions make it exceptionally comfortable in hand.
The revolver is fitted with checkered walnut stocks, adding warmth and contrast to the vibrant nickel finish. Every element of the Diamondback was designed with both function and refinement in mind. This resulted in a revolver that feels purpose-built yet undeniably elegant.
Discontinued in 1988 after a 22-year run, the Diamondback has steadily grown in collector appeal as examples become scarcer and appreciation for Colt’s classic revolvers continues to rise. While it never received the same level of hand-polishing or marketing attention as the Python, the Diamondback stands on its own merits as one of the most attractive and shootable small-frame revolvers Colt ever produced. For collectors and enthusiasts, it represents a perfect intersection of craftsmanship, practicality and unmistakable Colt heritage. The Colt Diamondback is an enduring classic from an era that many consider the pinnacle of American revolver making.
In short, it’s a classic Colt snake gun; what more needs to be said?
