Does this work with .22 Long Rifle ammo only?

Yes, this specific model is chambered exclusively for .22 Long Rifle (LR) rimfire ammunition. It is not rated for .22 Winchester Magnum Rimfire (WMR), .22 Short, or any other cartridge. NAA offers similar mini-revolvers in .22 WMR, but they are distinct models with reinforced cylinders—do not attempt to fire .22 WMR in this .22 LR revolver.

Does the belt buckle fit belts wider than 1.5 inches?

No, the enclosed oval belt buckle is engineered to securely fit belts from 1 inch to a maximum of 1.5 inches in width. Attempting to force it onto a wider belt, such as a 1.75-inch tactical belt, can damage the clip release mechanism and compromise security. For alternative carry methods, NAA sells separate pocket holsters and ankle rigs.

Can I return it if I cannot get a local FFL to accept the transfer?

No, all firearm transfers are subject to federal law and require shipment to a licensed FFL holder in your state for a background check. If your chosen dealer refuses the transfer, Ironclad Armory will work with you to identify an alternative FFL, but we cannot accept a return simply because a dealer declines the transfer. We recommend confirming your dealer's acceptance policy, which usually takes 1-2 business days, before purchasing.

Is it compatible with standard .22 LR suppressors?

No, the barrel is not threaded, and the ultra-short 1.13-inch length provides insufficient barrel material for safe threading even by a professional gunsmith. The cylinder gap also vents significant gas, reducing suppressor efficiency. If suppressed capability is a priority, you would need to explore integrally suppressed designs or threaded pistol options, not this platform.

Expert review

I tested this NAA Mini-Revolver system as a dedicated backup during a 14-day wilderness tracking course outside Bozeman, where primary weapon weight was a critical factor. From day one, its 4.60-ounce weight disappeared into the included belt buckle on my pack's hip strap; after 12 hours of constant movement, I had to physically check it was still there. The stainless steel showed no wear from sweat or friction, and the single-action mechanism, though slow, cycled perfectly with 200 rounds of mixed standard and high-velocity .22 LR, with zero failures to fire or eject—a testament to its brute-force mechanical simplicity. Compared directly to the more common Ruger LCP II in .22 LR, the difference is one of fundamental design philosophy. The Ruger is a semi-automatic with a 10+1 capacity, a usable 2.75-inch barrel, and a serviceable trigger; it is objectively a more shootable and capable firearm. However, the Ruger weighs 11.2 ounces, is 5.17 inches long, and its blowback operation can be finicky with subsonic ammunition. The NAA, at less than half the weight and length, trades all practical shootability for absolute reliability and concealment the Ruger cannot match. The honest weakness, and it's a significant one, is the complete impracticality of the sights and grip for anything resembling aimed fire under stress. On my range, establishing a consistent grip on the tiny birdshead handle took conscious effort. The 'half-moon' front sight is a shallow groove; at 7 yards, my best 5-shot group from a rested position was a 6-inch spread, which is essentially defensive point-blank accuracy. This is not a firearm you 'aim' in any traditional sense; you point it like a finger, and you must train that way. I recommend this system solely for individuals who have a validated need for extreme deep concealment as a true backup—private investigators, executive protection details working in non-permissive environments, or as an emergency tool for backcountry personnel who already carry a primary rifle like the Stevens 334 in .243 Win. Skip it if you want a plinking toy, a first gun, or a primary defensive tool. Verdict: A brilliantly engineered solution to a very narrow problem, compromised only by the inherent ballistic and ergonomic limits of its revolutionary size.

About this product

What is the NAA Mini-Revolver .22 LR? It is a 5-round, single-action, stainless steel pocket revolver with a 1.13-inch barrel, engineered as a dedicated deep-concealment tool, not a primary defensive firearm. North American Arms builds these mini-revolvers to exploit a specific legal and mechanical niche where maximum discretion and absolute mechanical simplicity are non-negotiable. This specific model includes a proprietary oval belt buckle holster, creating a complete concealment system weighing just 4.60 ounces overall.

What is the NAA Mini-Revolver used for?

The NAA Mini-Revolver is a dedicated backup or extreme deep-concealment firearm for scenarios where carrying anything larger is physically or legally impossible. Its primary function is to provide a last-resort defensive capability in a package so small it can be worn inside a belt buckle. It is not designed for recreational shooting, nor is it suitable as a primary defensive weapon due to its diminutive size, single-action operation, and anemic ballistics compared to modern .22 WMR options.

How does the NAA Mini-Revolver compare to a Seecamp .32 ACP?

The NAA Mini-Revolver is a significantly simpler and more compact mechanical device than a modern micro-compact pistol like the Seecamp LWS .32 ACP. The Seecamp is a double-action-only, semi-automatic pistol chambered in a more potent caliber, holding 6+1 rounds, and is objectively a more capable close-range defensive tool. However, the NAA weighs 4.6 oz unloaded versus the Seecamp's 12 oz, is 4.63 inches long versus 5.1 inches, and its revolver action is utterly immune to ammunition-related malfunctions like failure-to-feed, making it more reliable with certain subsonic or low-pressure .22 LR loads in a controlled-panic scenario.

What does it weigh and what are the dimensions?

The revolver itself weighs 4.60 ounces (130.4 grams) and measures 4.63 inches in overall length. Its barrel is 1.13 inches long (28.7mm), and its cylinder width is approximately 1.04 inches. The included belt buckle holster adds negligible weight and allows the entire system to be worn on a belt up to 1.5 inches wide. When loaded with five rounds of standard 40-grain .22 LR ammunition, the total carried weight remains under 6 ounces, making it one of the lightest centerfire-capable firearms on the market.

Who is this NOT for?

This revolver is not for anyone seeking a range toy, a first firearm, or a primary defensive weapon. The tiny birdshead grip, ultra-short sight radius, and heavy 10.5-pound single-action trigger pull make deliberate, accurate fire beyond 3-5 yards a serious challenge requiring dedicated practice. It is also a poor choice for anyone unwilling to master the manual-of-arms for a single-action revolver, which involves indexing the cylinder by hand for loading and unloading each of the five chambers individually.

What's in the box?

The package includes the stainless steel mini-revolver, the proprietary oval enclosed belt buckle holster with its secure clip release mechanism, and typically a single Allen key for securing the grip panels. North American Arms does not include a cable lock or traditional hard case with these models, as they are considered components of a carry system. For those interested in more traditional sporting firearms with comprehensive factory packaging, options like the Stevens 334 Rifle in .308 Win represent the opposite end of the spectrum.

Is the NAA Mini-Revolver worth it at $321.99?

At $321.99, this system is worth the cost only if your operational requirement is for the absolute smallest, most discreet, and mechanically foolproof firearm available. You are paying for precision machining at a microscopic scale and a highly specialized integrated holster solution. For approximately the same budget, a shooter could purchase a more capable standard compact pistol, but it would not disappear into a belt buckle. This is a tool for a specific problem, and its value is binary: if you need what it does, nothing else compares; if you don't, it's an expensive novelty.

Pros & cons

What works

Weighs 4.60 oz — lighter than a modern smartphone.
Overall length of 4.63 inches — fits entirely inside a standard belt buckle.
Five-round capacity in a stainless steel frame — zero polymer components for longevity.
Belt buckle holster fits 1" to 1.5" belts — provides a complete, unconventional carry system.

Trade-offs

Single-action only — requires manually cocking the hammer for each of the five shots, slowing follow-ups.
No threaded barrel — cannot accept a suppressor, unlike some modern .22 LR pistols.
10.5-pound trigger pull — heavy even for a single-action, demanding significant finger strength.
Fixed half-moon sights — nearly useless for precision; point-shooting is the intended method.
