Diamondback Firearms is introducing the Diamondback Sidekick, a 9-shot, single- and double-action rimfire revolver that has an interchangeable swing-out cylinder. The Sidekick has a 9-round capacity in either .22 LR or .22 Magnum. Both cylinders use the quickly convertible swing-out arm for fast interchangeability, allowing the user to switch between standard and magnum power in just seconds.

“Diamondback Firearms cut their teeth in the industry by producing their ultra-compacts DB380 and DB9 pistols and is also well known for its high-quality AR-15 rifles,” says Rachel Maitlitz, Marketing manager for Diamondback America. "This year, we are working hard to expand our product line and bring new designs to the market. The DB Sidekick is the latest product in the Diamondback lineup and helps expand Diamondback's product offerings into new areas."

The DB Sidekick combines classic cowboy style with all your favorite attributes of a modern revolver. The option of shooting either .22 LR or .22 Magnum gives you the ability to enjoy a firearm that is great for self-defense with manageable recoil, hunting small game, pest control, as well as some enjoyable and inexpensive target practice.

The Sidekick weighs 32.5 ounces and has added features, such as the cylinder release being incorporated to the ejection rod, a smooth black Cerakote finish and checkered polymer grip panels. The gun also has an integral rear sight, combined with a fixed-blade front. The Sidekick is initially offered with a 4.5-inch barrel having 1:16-inch twist, six-groove rifling and has an overall length of 9.875 inches.

The Sidekick is sure to be a popular choice for first-time owners and firearms enthusiast alike. Diamondback will officially launch the Sidekick on November 22, 2021. MSRP for the Diamondback with both the .22 LR and .22 Magnum cylinders is $320, and more information on this gun as well as other products from Diamondback Firearms is available at
