The Diamondback Firearms Sidekick Revolver brings a classic birds?eye cowboy silhouette to a modern convertible rimfire platform, offering shooters a 3" barrel, 9?round capacity, and the flexibility of .22LR and .22 Magnum cylinders for everything from range plinking and inexpensive marksmanship training to small?game field work and backyard target sessions. The Sidekick series blends old?school looks with practical features: an exposed hammer and DA/SA action for both double?action carry and single?action precision, a swing?out cylinder release cleverly incorporated into the traditional ejection rod, and a smooth black Cerakote finish over a zinc alloy frame for corrosion resistance and subdued presentation. At 24.5 oz and an overall length of 7.83", the compact footprint and black birdshead polymer grip make it comfortable for short?carry or as a dependable truck gun, while a 1:16 RH twist with six grooves and blade front/integral rear sights support consistent rimfire ballistics. Included second cylinder converts the platform between .22 Long Rifle and .22 Magnum, giving owners economical range sessions or hotter magnum performance without buying a second revolver. FFL required for transfer; the Sidekick is a versatile choice for shooters seeking a lightweight, historically styled revolver with modern convenience and rimfire adaptability.
