The Diamondback Sidekick revolver (brand part no. DB0500A001) is a cowboy-style .22 LR/.22 Magnum convertible, shipping with two interchangeable 9-round cylinders so shooters can switch between standard and magnum rimfire power in seconds. Diamondback Firearms builds the Sidekick with a swing-out cylinder release worked into a traditional ejection rod, a smooth Black Cerakote finish, and checkered glass-filled nylon grips. The 4.5-inch barrel carries a 1-in-19 twist, the action runs double action/single action, and a blade front sight pairs with a fixed rear for quick target acquisition; the frame is finished with a hammer safety. Among convertible revolvers, the Sidekick favors shooters who want one gun that covers plinking, small-game hunting, and manageable-recoil practice.
