While the Sidekick models an old school cowboy revolver keeping with that classic look and feel, Diamondback added features like the cylinder release being incorporated to the old school ejection rod, a cool smooth black Cerakote finish, and checkered polymer grip panels. Diamondback went with a rear integral and a fixed front blade sight. The Sidekick is chambered in .22 LR with a 9-shot cylinder but also comes with an additional 9-shot cylinder chambered in .22 Mag, allowing you 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.
