Some tools earn a place in your kit not because they’re flashy, but because they deliver—every time. When I think about a rimfire revolver that can handle training, small-game duty, and range fun without fuss, I look for rugged construction, consistent accuracy, and a system that adapts to the mission. That’s where a dual-caliber rimfire shines, giving you options without complicating your life.
DIAMONDBACK Sidekick
Why this rimfire revolver earns its place
Diamondback built the Sidekick around a practical idea: switch between .22 LR and .22 Magnum with a quick cylinder change, no drama. That versatility lets you train affordably with .22 LR, then step up to .22 Mag for more authority when you need it—varmint control, trail carry, or camping duties. The package includes an extra cylinder out of the box, so you’re not hunting for aftermarket parts later.
The frame is zinc alloy to keep weight and cost down, while the barrel and cylinder are steel where it counts. The Cerakote finish shrugs off sweat, dust, and the kind of hard use a revolver sees when it lives in a pack, truck console, or on the range week after week. A blade front sight paired with an integral rear sight keeps the profile snag-free and simple—fast to acquire, consistent to run.
Dual-caliber advantage: .22 LR and .22 Magnum
.22 LR: affordable training and skill building
.22 LR is where you develop fundamentals. It’s easy on recoil, cost-effective, and perfect for repetition. Dry fire builds trigger discipline; live fire confirms it. On the Sidekick, .22 LR lets you practice single- and double-action work, sight alignment, and follow-through without beating up your wallet. For introducing new shooters, the controllable nature of .22 LR is a confidence builder and a safe on-ramp when paired with proper supervision and range protocols.
.22 Magnum: more reach, more punch
Swap to the .22 Mag cylinder and you’ll feel the difference. .22 Magnum offers flatter trajectories and more energy on target compared to .22 LR, which matters for small-game hunting, pest control, or when you’re packing a light, low-recoil sidearm on the trail. The Sidekick’s steel barrel and cylinder are up to the task, and the sight picture remains crisp and predictable across both calibers, helping you keep hits consistent.

Build and features that matter in the real world
Materials chosen for durability and value
The zinc alloy frame trims weight and cost, but the Sidekick doesn’t compromise where it counts—steel for the barrel and cylinder to handle the pressures and heat of repeated firing. The Cerakote finish is the quiet professional here: corrosion resistance, abrasion resistance, and a subdued appearance that plays well in the field.
Sighting system: simple, reliable, repeatable
A blade front sight with an integral rear is a classic rimfire revolver setup. It’s snag-resistant when drawing from a pouch or glove compartment, yet easy to track across a target. This setup encourages proper sight focus and clean trigger work—skills that transfer to your centerfire handguns.
Switching cylinders: fast and straightforward
The included extra cylinder is the heart of the Sidekick’s dual-caliber system. With practiced hands, the swap is quick and intuitive. No extra tools on the belt, no delicate parts to lose. When you’re transitioning from a training session to field work, that speed counts.
Where the Sidekick fits in your kit
As a Revolver in the rimfire class, the Sidekick keeps things uncomplicated. It’s ideal for:
- New shooter development: light recoil and clear feedback loop for fundamentals
- Range reps: affordable .22 LR sessions to sharpen mechanics before centerfire days
- Small-game and pest control: .22 Mag brings more authority with manageable muzzle blast
- Trail companion: weather-resistant finish, reliable ignition, minimal maintenance
Diamondback’s reputation for delivering practical, budget-conscious firearms shows here. You’re getting a dual-caliber system with steel where you need strength, a finish that handles the elements, and sights that keep the gun honest. At a price point of $275.99 on our shop page, the value proposition is strong—especially considering the included extra cylinder.
Performance notes from the range
In .22 LR, expect minimal recoil and rapid follow-up shots. The trigger encourages clean presses when you focus on a straight-to-the-rear pull. For .22 Magnum, you’ll notice a sharper impulse and livelier report—still very controllable, with benefits downrange in terms of energy and clarity on steel. The zero remains consistent; the sight alignment demands the same disciplined approach across both cylinders, which is exactly what you want from a training-forward rimfire revolver.
Practical carry and maintenance
Rimfire revolvers reward routine: keep chambers clean, inspect ammunition, and maintain light lubrication. The Cerakote finish buys you margin when life gets dusty or wet. Stow it in a dedicated pouch or soft case to protect the sights and finish. Revolver manual of arms is straightforward—load, close, confirm, and run your checks. Simple is good, especially when you’re juggling gear or mentoring a new shooter.
Who will appreciate this platform
If you’re a seasoned shooter looking for a cost-effective way to sharpen fundamentals, the Sidekick is a solid training partner. If you’re building skills for a new shooter, its approachable recoil, consistent sight picture, and dual-caliber flexibility keep the learning curve smooth. And if you’re after a packable utility revolver for the homestead or campsite, .22 Mag capability in a weather-resistant package checks the right boxes.
