The Diamondback Firearms Sidekick .22LR/.22 WMR revolver is a compact, dual-caliber handgun built for plinking, small-game hunting, and target shooting. This 4.5" barrel revolver handles both .22 Long Rifle and .22 Magnum ammunition with the included convertible cylinders, giving you flexibility to match your ammunition choice to the job at hand. The 9-round capacity, single- and double-action trigger, and straightforward mechanical design make it an approachable option for shooters who want reliability without unnecessary complexity.
The Sidekick's Midnight finish—a sleek black Cerakote over a zinc frame—resists wear and corrosion during regular use. The checkered glass-filled nylon grips provide a secure, comfortable purchase whether you're shooting one-handed or supported. At 32.5 ounces and 9.875 inches overall length, it balances portability with a long-enough sight radius for accurate shots downrange. Integral rear sight and a simple blade front sight keep the gun lightweight and snag-free, ideal if you're carrying it afield.
This revolver appeals to shooters building a beginner-friendly rimfire collection, anyone after an affordable training gun, or folks who appreciate the mechanical simplicity and low recoil of .22 shooting. The dual-caliber capability means you can load up with economical .22LR for high-volume range days or step up to .22 Magnum when a little more punch matters. Whether you're teaching, plinking, or hunting small game, the Sidekick delivers straightforward revolver handling without premium pricing.
