Diamondback Sidekick Convertible .22 LR/.22 WMR 9-Shot Revolver – 4.5 in Barrel, DA/SA, Dark Grey Cerakote
Released in 2021, the Diamondback Sidekick Convertible brings a fresh take on the classic plinking revolver by pairing a 9-shot capacity with a quick-change cylinder system that lets you shoot either .22 LR or .22 WMR. Its hybrid design combines single-action styling with a swing-out, double-action/single-action mechanism, giving you modern handling without losing old-school charm. A durable dark grey Cerakote finish, checkered glass-filled nylon grips, and a 4.5-inch barrel round out a package built for versatile rimfire fun.

What’s Included
- Factory Diamondback Sidekick .22 WMR 9-shot conversion cylinder
The Sidekick’s standout feature is its convertible cylinder system. A forward push on the ejector rod both releases the swing-out cylinder and ejects spent cases, allowing you to swap between the included .22 LR and .22 WMR cylinders in seconds. Each cylinder holds nine rounds, offering more shots between reloads than traditional six-shooters.
Diamondback machines the frame, barrel, and cylinder from zinc-alloy and protects them with a matte dark grey Cerakote finish for corrosion resistance and a consistent, non-glare look. Fixed blade front and integral rear notch sights provide a simple, rugged sighting setup that stays on target.
The revolver’s double-action/single-action trigger lets you choose between rapid DA fire or precise SA shots. A 1:16 RH barrel twist stabilizes a wide range of rimfire loads, while the external hammer and smooth trigger face keep controls familiar for seasoned wheel-gun shooters.
Full-size proportions—9.88 in overall length and roughly 32 oz unloaded—give the Sidekick a steady feel without excessive heft. Checkered glass-filled nylon grips offer a secure, weather-resistant hold and complement the modern finish.
