Let’s talk about the Diamondback Sidekick 22 Long Rifle 4.5in Zinc Alloy Pistol – 9 Rounds. I’ve been building online firearm platforms for over a decade, and I see a lot of .22 LR pistols come through our warehouse in Boise. This one stands out for a specific reason: it’s built for a purpose. It’s not a target pistol, and it’s not trying to be a high-end collector’s item. It’s a functional, affordable tool designed for utility. When you’re looking at a price point under four dollars, the conversation shifts from luxury features to raw, practical application. This is a pistol that understands its role, and its construction—a zinc alloy frame with a 4.5-inch barrel—speaks directly to that. It’s a platform for plinking, for introducing new shooters to handgun fundamentals without intimidation, or for a lightweight, low-recoil option where centerfire power isn’t the primary objective. The 9-round capacity is a practical number, balancing shootability with a manageable profile. From my perspective as an armorer, the design choices here are deliberate, favoring cost-effective durability and simplicity over complex machining. Let’s get into what that means for you on the range.

What You’re Getting with the Diamondback Sidekick
This isn’t a gun you disassemble and marvel at the internal polishing. You buy the Diamondback Sidekick 22 Long Rifle 4.5in Zinc Alloy Pistol – 9 Rounds to use it. The zinc alloy frame, often called Zamak or pot metal in the industry, is the cornerstone of its value proposition. It’s a casting that allows for complex shapes at a very low cost, and when finished properly, it provides good resistance to the elements. The 4.5-inch barrel length is a sweet spot for .22 LR, giving you a decent sight radius for improved accuracy over snub-nose variants while keeping the overall package compact and holster-friendly. The 9-round cylinder capacity is generous for a .22 revolver, meaning more time shooting and less time reloading during a session. The single/double action trigger is a standard feature for this class, offering the option for a deliberate, long single-action pull or a quicker, heavier double-action pull. The finish is a basic black, designed for function, not flash. From an armorer’s bench, this is a straightforward design: simple mechanics, easy to clean, and built with materials that keep the entry cost accessible. I’ve handled enough of these to know that their reliability, within the context of their design intent, is generally solid.
Key Features & Performance Breakdown
The heart of this pistol is its zinc alloy frame. In the firearms world, this material gets a mixed reputation, but that’s often from people comparing it to forged steel or aluminum. That’s not a fair fight. Zinc alloy is used here because it meets the specific stress and corrosion requirements of the .22 Long Rifle cartridge while drastically reducing manufacturing cost. For a low-pressure round like .22 LR, it’s more than sufficient. You won’t be putting tens of thousands of rounds through it like a competition gun, but for its intended life as a plinker or trainer, it holds up. The 4.5-inch barrel is rifled steel, which is the critical component for accuracy. This length helps stabilize standard and high-velocity .22 LR rounds effectively, giving you consistent groups at typical plinking distances of 10-25 yards.
The 9-round cylinder is a notable feature. Many classic .22 revolvers top out at 6 or 8 rounds. The extra capacity here is a practical advantage. Loading is done via a side-loading gate, a traditional revolver method that promotes deliberate shooting and reinforces firearm handling safety—a good trait for a training pistol. The fixed sights are simple and non-adjustable, which again speaks to the pistol’s role. They are set for a combat-style point of aim at a reasonable distance. If you’re looking for a pistol to dial in for bullseye shooting, you’ll need an adjustable-sight model. For instinctive shooting and general familiarization, these fixed sights are perfectly adequate. The overall weight and balance are light, thanks to the zinc alloy. This makes it easy to carry and handle, especially for shooters with less hand strength, but it does mean you’ll feel a bit more snap from the .22 LR report compared to a heavier steel-framed revolver.
Pros and Cons: The Straight Talk
✅ Pros:
- Exceptional Value: At this price point, it provides a functional, shootable .22 LR handgun.
- Low Maintenance: Zinc alloy and a simple blued finish resist rust and are easy to wipe down.
- Ideal Trainer: The light weight, minimal recoil, and simple manual of arms make it excellent for new shooters.
- Generous Capacity: The 9-round cylinder means less frequent reloading during range sessions.
- Readily Available Ammo: .22 LR is one of the most common and affordable cartridges to feed it.
❌ Cons:
- Material Limits: The zinc alloy frame is not as durable long-term as steel or aluminum. It’s for standard-pressure .22 LR, not +P or continuous high-volume fire.
- Fixed Sights: Limits precision adjustment. If you need target-grade accuracy, see our target pistols for alternatives with adjustable sights.
- Basic Finish: The finish is utilitarian and can wear with heavy holster use. It’s a tool finish, not a display finish.
Who This Pistol Is For (And Who Should Look Elsewhere)
Buy the Diamondback Sidekick 22 Long Rifle 4.5in Zinc Alloy Pistol – 9 Rounds if: You’re a first-time handgun buyer wanting an ultra-affordable entry into shooting. You’re an experienced shooter looking for a dedicated, low-cost .22 LR plinker for casual range trips. You’re an instructor or parent seeking a safe, simple, low-recoil platform for teaching fundamentals. You want a lightweight, compact revolver for trail carry or pest control where .22 LR is sufficient.
Skip the Diamondback Sidekick and consider an alternative if: You demand match-grade accuracy or intend to use it for formal competition (look at our .22 target pistols). You plan on putting thousands of rounds through it annually and need a heirloom-duty firearm (consider a steel-framed revolver). You require a defensive firearm; while .22 LR can be used for defense, it is not generally recommended as a primary cartridge.

Frequently Asked Questions
Is the Diamondback Sidekick a good gun for a beginner?
Yes, it can be. Its simple revolver operation, light recoil, and affordable ammunition make it a suitable platform for learning basic safety, grip, sight alignment, and trigger control. Always seek professional instruction when starting out.
What kind of .22 ammunition should I use in it?
Stick with standard velocity or high-velocity .22 Long Rifle rounds from reputable manufacturers. Avoid hyper-velocity or “stinger” type rounds, as they generate higher pressure and are not necessary for this pistol’s design role.
How do I clean and maintain a zinc alloy firearm?
Field strip according to the manual. Use standard gun cleaning solvents and oils. Wipe down the zinc alloy frame to remove fingerprints and moisture. The key is preventing corrosion, though the alloy itself is fairly resistant. Focus cleaning on the steel barrel and cylinder.
Can I use this for small game hunting or pest control?
With accurate shot placement, .22 LR is effective for small game and pests at short ranges. The 4.5-inch barrel and fixed sights are capable of this within typical distances. Ensure you comply with all local game laws.
Is the finish durable?
The blued finish is a basic commercial coating. It will protect against rust under normal conditions but can holster-wear or scratch with abrasive use. It’s a functional finish, not a decorative one.
