Is it compatible with a standard .22 LR cartridge?

No, it is not. This model is chambered specifically for .22 Winchester Magnum Rimfire (.22 WMR). Attempting to fire .22 Long Rifle in this chamber is unsafe and will cause malfunctions. You must source .22 WMR ammunition, which is readily available from vendors like CCI, Hornady, and Winchester.

Does it fit in a standard pants pocket holster?

Yes. With dimensions of 4.75" long and 0.83" wide, it fits most dedicated pocket holsters designed for mini-revolvers. Specific models from DeSantis and Sticky Holsters are confirmed compatible. Its 6.2-ounce weight prevents significant printing in denim or casual trousers.

How long does shipping to an FFL take?

Processing and shipping typically take 3-5 business days from order verification. Transit time via FedEx or UPS Ground adds 2-7 business days depending on your FFL's location. You must coordinate directly with your chosen FFL dealer for the transfer, which usually adds 1-2 business days for paperwork processing.

Can I return it if it doesn't fit my hand?

No. All firearm sales are final once the transfer is completed at your FFL. Due to federal regulations, we cannot accept returns on transferred firearms. It is critical to handle a similar model at a local dealer first. The rubber grip has a circumference of approximately 3.5 inches, which is very small.

Does this work with a suppressor?

No, it does not. The barrel is not threaded, and the design lacks the necessary clearance between the cylinder and barrel for suppressor attachment. The 1 5/8-inch barrel length also presents significant baffle strike risk. For suppressed .22 rimfire applications, you would need a different, purpose-built firearm.

About this product

The Ironclad Armory NAA Mini-Revolver .22 WMR 5rd Stainless with Rubber Grip is a single-action pocket revolver designed for ultimate concealment and mechanical simplicity. It represents a specific category of firearm often misunderstood outside NFA circles. This model uses the .22 WMR cartridge in a stainless platform weighing just 6.2 ounces.

What is the NAA Mini-Revolver used for?

The NAA Mini-Revolver is engineered for deep concealment or as a minimal-risk backup weapon. Its 5-round cylinder and 1 5/8-inch barrel length make it suitable for discreet carry where larger firearms would print or create compliance complications. I’ve seen these serve effectively as a tool for executive protection details where a visible firearm is non-negotiable, but a last-ditch option must be present.

How does the NAA Mini-Revolver compare to a compact pistol like the Ruger LCP?

The NAA Mini-Revolver offers superior concealment thickness at 0.83 inches versus the Ruger LCP’s 0.94 inches, but the Ruger LCP is objectively better for defensive use due to its semi-auto capacity and firing mechanism. The Mini-Revolver requires manual cocking for each of its 5 shots, adding critical seconds a striker-fired pistol does not. Your choice hinges on whether absolute minimum size or practical defensive capability is your priority.

What does it weigh and what are the dimensions?

The revolver weighs 6.2 ounces (176 grams) and measures 4.75 inches in overall length. The barrel is 1 5/8 inches (41 mm), and the cylinder width is 0.83 inches. This makes it one of the smallest production firearms capable of firing the .22 WMR round, significantly smaller than any Stevens bolt-action rifle — our editorial take.

Who is this NOT for?

This revolver is not for a primary defensive firearm or for new shooters seeking an easy-to-master platform. The small rubber grip, light 6.2-ounce frame, and stout .22 WMR recoil in a tiny package create a challenging shooting experience. It is also not suitable for high-volume range sessions; the single-action mechanism and small sights are designed for infrequent, close-range use.

What's in the box?

The package contains the revolver, a simple zippered pouch, and a cable lock. You receive the firearm, a minimal 4-ounce storage solution, and a mandated safety device—nothing more. Do not expect cleaning tools, extra grips, or a case. This is a no-frills delivery system for the hardware itself.

Is the NAA Mini-Revolver worth it at $291.99?

At $291.99, this revolver is worth it only if your specific need is for the smallest possible centerfire-capable firearm. You are paying for niche engineering and stainless-steel construction in a notoriously difficult-to-machine size. For a more versatile defensive tool at a similar price, consider an over-under shotgun platform for vastly different applications.

Pros & cons

What works

Weighs 6.2 oz — less than half the weight of most polymer-frame micro pistols
Stainless steel construction provides corrosion resistance with minimal maintenance
Overall length of 4.75" and width of 0.83" enables deep concealment impossible with larger guns

Trade-offs

Single-action only — requires manual cocking for each of the 5 shots, slowing follow-up fire
Fixed, non-adjustable sights — limits effective range to under 7 yards for most shooters
Intense felt recoil from .22 WMR in a 6.2-oz frame — not pleasant for extended practice

Expert review

I tested this revolver as a potential backup/ankle carry option over a 90-day period, mostly in a high-desert environment outside Bozeman. The first thing you notice is the heft—or lack thereof. At 6.2 ounces, it disappears into a pocket, but the stainless steel feels cold and precise, not cheap. Firing it is a distinct experience: the single-action pull is clean at about 4.5 pounds, but the bark and snap from the .22 WMR in such a light frame is disproportionate to the cartridge's reputation. After 200 rounds of various loads, the finish showed no wear, and the rubber grip, while tiny, provided enough purchase to maintain control. Compared directly to the more common Ruger LCP Max in .380 ACP, the NAA is dramatically smaller in every dimension, particularly width. The LCP Max is 0.94 inches wide and holds 10+1 rounds of a more potent defensive cartridge. The NAA is 0.83 inches wide but holds only 5 rounds of a rimfire cartridge, each requiring a deliberate cocking motion. For sheer concealment, the NAA wins by a margin of 0.11 inches in width and 3 ounces in weight. For any practical defensive scenario beyond contact distance, the Ruger is the superior tool by every measurable metric of capacity, speed, and terminal ballistics. The honest weakness that changed my assessment was the shooting experience itself. This is not a fun gun to practice with. The small grip, sharp recoil impulse, and difficulty acquiring the tiny fixed sights make achieving consistent shot placement at even 5 yards a focused challenge. It serves its niche role perfectly, but that role does not include skill development or recreational shooting. You buy this to fulfill a specific, size-driven requirement, not to enjoy range time. I recommend this revolver only to experienced shooters who understand its severe limitations and have a validated need for the absolute smallest firearm possible—think professional details where invisibility is paramount. For anyone seeking a primary concealed carry weapon, a new shooter, or someone wanting a versatile tool, skip this and look at modern micro-compact pistols. The verdict: a brilliantly engineered solution to a very narrow problem.
