The Diamondback Sidekick Revolver .22 LR/.22 Mag, 9-Round is a convertible wheelgun that pulls double duty in your kit. It ships with two cylinders—one for .22 LR and one for .22 Magnum—so you can switch between plinking rounds and hotter defensive loads without swapping guns. Double- and single-action operation, an exposed hammer, and fixed sights keep it straightforward. Per manufacturer specs, the frame is a zinc alloy with a black Cerakote finish, and the checkered polymer grip panels give you traction even with sweaty hands. At $295, it’s a budget-friendly option for anyone who wants a rimfire revolver that pulls double duty on the range or in the field.

Key Features
- Convertible Cylinder System — Why it matters: You get two cylinders in the box, so you can run cheap .22 LR for practice and switch to .22 Magnum for more punch without buying a second gun.
- Double- and Single-Action Trigger — Why it matters: You can shoot fast in double-action for follow-up shots or thumb the exposed hammer for a crisp single-action pull when precision matters.
- Fixed Blade Front and Integral Rear Sight — Why it matters: No snag points on the draw, and the low-profile sights stay zeroed without adjustment—ideal for a carry revolver or trail gun.
- 9-Round Capacity — Why it matters: You get two more rounds than a typical 7-shot .22 revolver, which means more time shooting and less time reloading on the range or in a defensive scenario.
- Black Cerakote Finish — Why it matters: Cerakote resists corrosion and scratches better than standard bluing, so the Sidekick holds up to sweat, rain, and holster wear during daily carry.
Who It’s For
This revolver fits the EDC crowd that wants a lightweight rimfire for backup carry, trail hiking, or teaching new shooters. It’s also a solid pick for anyone who wants one gun that eats both .22 LR and .22 Magnum without fiddling with tools—just swap cylinders. If you’re a pocket-dump guy who carries a fixed blade and a flashlight, the Sidekick is the revolver that pairs with your setup.
Pros & Cons
- Pros: Affordable price point ($295), convertible caliber system, 9-round capacity, Cerakote finish for durability, exposed hammer for single-action accuracy.
- Cons: Zinc alloy frame is lighter but not as durable as steel for heavy use; fixed sights limit adjustability for different loads.

The Diamondback Sidekick stands out with its double-action capability—neither the Ruger Wrangler nor the Heritage Rough Rider offer that. It also packs 9 rounds versus 6, giving you more firepower in a similar package. The trade-off is a slightly higher price than the Heritage, but you get a more modern revolver that’s ready for both range and carry use.
FAQ
Can I shoot .22 Short or .22 Long in this revolver?
No, the Sidekick is designed specifically for .22 LR and .22 Magnum (22 WMR) cartridges. .22 Short and .22 Long cases are shorter and may not feed or fire reliably. Stick to the two calibers listed in the specs.
How do I switch between the .22 LR and .22 Magnum cylinders?
Open the cylinder latch, pull the cylinder pin forward, and slide the cylinder out. Swap in the other cylinder, reinsert the pin, and close the latch. No tools needed—it takes about 10 seconds once you’ve done it a couple times.
Is this revolver safe for concealed carry?
Yes, the 3-inch barrel and 30-ounce weight make it manageable for belt or pocket carry with a sturdy holster. The exposed hammer can snag on draw if you’re not careful, so practice your presentation. The double-action trigger gives you a heavier pull for added safety during carry.
Does the Sidekick come with a case or lock?
Yes, it ships in a cardboard box with a cable lock and owner’s manual, per standard manufacturer packaging. Some retailers may include a soft case, but check with your seller for specifics.
What’s the trigger pull weight in double-action?
Per user reports and manufacturer specs, the double-action pull is approximately 10-12 pounds. The single-action pull is lighter, around 4-5 pounds, which is typical for a rimfire revolver.
