The Diamondback Firearms Sidekick is a convertible rimfire revolver that combines classic cowboy styling with practical modern features. Chambered for both .22 LR and .22 WMR, it includes two interchangeable 9-shot cylinders, giving shooters the flexibility to use economical .22 LR ammunition for target practice or the additional performance of .22 WMR for small-game hunting and pest control. Its double-action mechanism also retains single-action capability for deliberate, precise shots. The 4.5-inch barrel, fixed front blade, and integral rear sight create a straightforward sighting setup, while the swing-out cylinder arm makes changing cylinders and reloading efficient. A Dark Gray Cerakote finish protects the zinc frame and handle, and checkered glass-filled nylon grip panels provide a dependable, comfortable grip. At 32.5 ounces, the Sidekick offers manageable recoil and convenient handling for a wide range of rimfire applications.
