NAA Mini-Revolver .22 WMR/.22 LR 5-Round Stainless

The NAA Mini-Revolver .22 WMR/.22 LR 5-Round Stainless is the smallest production revolver I’ve ever tucked in a pocket—and I’ve carried a lot of iron over the years. This stainless-steel, five-shot single-action combo ships with a .22 WMR cylinder pre-installed and a spare .22 LR conversion cylinder in the box. That means you can run hot magnum loads for defense or plink cheap .22 Long Rifle all day with the same gun. The folding holster grip locks open for shooting and snaps closed over the trigger for safe carry. At this price—$354.76—it’s the most versatile deep-concealment revolver I know of. Let’s dig into why this NAA Mini-Revolver .22 WMR/.22 LR 5-Round Stainless belongs in your rotation.

Key Features

• Dual-Caliber Combo Cylinders: The gun ships with a .22 WMR cylinder installed and a spare .22 LR cylinder in the box. You can swap cylinders in under 30 seconds—no tools. Why it matters: One revolver covers plinking, small-game hunting, and defensive carry without buying a second gun.
• Folding Holster Grip with Locking Positions: The black polymer grip folds out to become a shooting grip, then snaps shut to cover the trigger guard—with a belt/pocket clip built in. Why it matters: You get a holster and grip in one unit; no extra gear needed for pocket or waistband carry.
• Exposed Hammer for Single-Action Precision: The spur hammer lets you thumb-cock for a crisp single-action trigger pull. Why it matters: Single-action accuracy is legendary—you can place each round exactly where you want it, even from a tiny barrel.
• All-Stainless Construction: Frame, barrel, and cylinders are machined from 400-series stainless steel. Why it matters: No rust worries in sweaty pockets or humid environments; this revolver will outlast you with basic care.
• Five-Round Capacity in a Package Smaller Than a Credit Card: Overall length is just 5.125 inches with the grip folded. Why it matters: It disappears in a front pocket, ankle holster, or even a watch pocket on jeans—true always-on-you carry.

Who It’s For

This revolver is for the collector who wants a functional mini-gun that’s also a conversation starter at the gun show. It’s for the shooter who values a backup piece that fits in a coin pocket. And it’s for anyone who wants a rimfire revolver that can run both magnum and LR without buying extra parts. If you’re building a collection of unique, compact firearms, this NAA Mini-Revolver belongs in the safe.

Pros & Cons

• Pros: Tiny enough to carry anywhere; dual cylinders for versatility; stainless steel requires no finish care; folding grip doubles as a holster; affordable entry to collectible mini-revolvers.
• Cons: Single-action only—you must manually cock the hammer each shot. The grip is small, so shooters with larger hands may find it cramped for extended range sessions. Per North American Arms, the .22 LR cylinder should be used only with standard-velocity loads for best accuracy.

FAQ

Can I shoot .22 LR without swapping cylinders?

No—the .22 WMR cylinder will not chamber .22 LR safely. You must remove the magnum cylinder and install the included .22 LR cylinder. The process takes about 30 seconds and requires no tools. Per NAA specs, always verify cylinder marking before loading.

Is the folding grip comfortable to shoot?

Yes, for a gun this small. The polymer grip locks open at a 90-degree angle and gives you a three-finger hold. It’s not a full-size revolver grip, but it’s surprisingly controllable with .22 WMR loads. For extended shooting, I recommend a grip sleeve from NAA.

How do I clean the conversion cylinder?

Clean the .22 LR cylinder the same as the magnum cylinder: remove from the gun, wipe down with solvent, and brush the chambers with a .22-caliber bore brush. Re-oil lightly before storing. NAA recommends cleaning after every 50 rounds to maintain reliability.

Does the belt clip work for appendix carry?

Yes—the clip is reversible for left- or right-hand carry, and it fits belts up to 1.5 inches wide. I’ve appendix-carried this revolver in gym shorts with the clip over the waistband. It stays secure and prints less than a wallet.

This NAA Mini-Revolver .22 WMR/.22 LR 5-Round Stainless is a must-have for collectors who appreciate clever engineering and shooters who want a reliable backup. It’s small enough to forget you’re carrying, but potent enough with .22 Magnum to handle close-range defense. At $354.76, it’s one of the best values in rimfire revolvers today.
