The Diamondback Firearms Sidekick is a classic-style convertible rimfire revolver chambered for both .22 LR and .22 WMR. It includes two interchangeable 9-shot cylinders, allowing shooters to switch between economical .22 LR ammunition and the more powerful .22 WMR cartridge. Its 4.5-inch barrel, black Cerakote finish, and checkered polymer grip panels provide a practical combination of durability, handling, and traditional cowboy-revolver styling. Fixed blade and integral rear sights support a straightforward aiming picture for target practice, small-game use, pest control, and recreational shooting.
