Legacy Double Nine Led to Sidekick at Diamondback

At the 2024 SHOT Show industry day at the range, this correspondent stopped at the Diamondback Firearms booth. Unfortunately, they did not have any examples of their new .22 revolver, the Sidekick, available. This lead to a discussion of how the Sidekick, which strongly resembles the old Hi-Standard Double Nine revolver, was brought into production.

Jimmy Stroda was the director of product development at Diamondback Firearms. He related the story to this correspondent. Diamondback had been looking at product sales in the United States. It is clear that .22 caliber single-action revolvers have a very large market share, as seen by the number of Heritage arms revolvers that are sold every year. Diamondback management believed they could capture part of this market. They started to make plans to produce a .22 single-action revolver. Then Ruger entered the inexpensive end of the market with the Wrangler series of revolvers. Diamondback was reconsidering its options.

Jimmy had a legacy Hi-Standard Double Nine revolver he inherited from his grandfather. He thought highly of the handgun. The Double Nine is a nine-shot, double-action revolver styled to look and handle much like a Colt single-action revolver. It fires both double and single action. It has a side swing out cylinder and ejects all nine cartridges at once. It has the advantages of a single-action style with double-action mechanics and ease of loading and unloading. It can be supplied with a magnum cylinder to give more versatility to the handgun.

The owner of Diamondback was considering the idea of manufacturing a double-action .22 revolver. Jimmy put forward the idea of re-creating a modern version of the Hi-Standard Double Nine. Another member of the management team piped up. He had one of the legacy Double Nine revolvers and thought it was a great gun. Diamondback decided to move forward with a new version of the Hi-Standard. During development, they contacted previous Hi-Standard management. Any patents were long out of date. The previous management was very helpful, suggesting areas where Hi-Standard had problems and how they had been solved. Jimmy has since moved to Diamondback Knifeworks.

The Sidekick uses a zinc alloy casting for the frame. The Hi-Standard Double Nine used an aluminum casting for the frame. Diamondback has strong experience with both zinc and aluminum casting. Zinc frames result in a revolver with a weight closer to the original Colt single action, so a zinc alloy was chosen. The Heritage revolvers use a similar material in their frames.  The Ruger Wrangler uses an aluminum casting for the frame. The Ruger Super Wrangler has a steel frame.

The Double Nine was offered in a variety of colors and finishes. The Sidekick is offered in a variety of cerakote colors. There are advantages to .22 rimfire revolvers, which make them competitive with .22 semi-automatic handguns. This correspondent has owned several of the Hi-Standard Sentinel .22 revolvers. The Double Nine is a variant of the Sentinel design.  The Diamondback team is always working on improvements. This correspondent expects the Sidekick to maintain and build on the legacy of the Hi-Standard Double Nine.
