About this product
The NAA Mini-Revolver .22 WMR/.22 LR 5-Round Stainless is a compact, five-shot, single-action stainless steel pocket revolver designed for deep concealment and close-quarters emergency use.
This isn't a target pistol or a primary defensive sidearm—it's a last-resort tool built around mechanical redundancy and regulatory compliance. The inclusion of both a .22 WMR cylinder and a .22 LR conversion cylinder addresses both ballistic effectiveness and ammunition availability concerns.
What is the NAA Mini-Revolver used for?
The NAA Mini-Revolver is engineered specifically for deep concealment as a backup or tertiary firearm in scenarios where carrying anything larger is impractical.
Its 4.9-ounce frame and 2.5-inch overall length allow it to disappear in a pocket, boot, or lanyard carry in environments with stringent weapon restrictions. While a Stevens 334 Rifle is your tool for deliberate hunting, this is for the moment you need a single-handed, contact-distance option that cannot snag or print.
How does the NAA Mini-Revolver compare to a small-frame .38 snub-nose?
The NAA Mini-Revolver is fundamentally more concealable and lighter than any small-frame .38 snub-nose, but far less capable in terms of terminal ballistics and practical rate of fire.
For example, a typical snub-nose revolver like a Smith & Wesson Model 642 weighs around 15 ounces, holds 5 rounds of .38 Special, and allows for double-action firing. The NAA weighs less than a third of that and is single-action only, requiring you to cock the hammer for every shot. The snub-nose is better for primary, close-range defensive use; the NAA is better for absolute invisibility.
What does it weigh and what are the dimensions?
The stainless steel frame of the NAA Mini-Revolver weighs 4.9 ounces (139 grams) and measures 4.1 inches in length with a 1.125-inch barrel.
When closed within its integral polymer holster grip, the package is a sealed unit measuring just 2.5 inches in height. This profile is critical—it's thinner and lighter than most multi-tools, allowing it to be a true pocket-watch replacement in a vest or trouser pocket without telegraphing its presence.
Who is this NOT for?
This revolver is not for new shooters, those seeking a primary self-defense handgun, or anyone who dislikes meticulous manual-of-arms.
The manual safety system involves rotating the cylinder to a safety notch between chambers to block the hammer, a step easily forgotten under stress. The tiny sights and stout recoil of the .22 WMR round in a 4.9-ounce frame make precise shooting past 15 yards a challenge. If your needs lean towards long-range or high-volume shooting, a Stevens 555 Sporting Shotgun would be a more suitable starting point.
What's in the box?
The package includes the stainless steel NAA Mini-Revolver frame, both a .22 WMR cylinder and a dedicated .22 Long Rifle conversion cylinder, the locking polymer holster grip, and a metal belt/pocket clip.
NAA ships only the conversion cylinder with the base firearm; you must source .22 WMR and .22 LR ammunition separately. Unlike many modern pistols, there is no cleaning kit, cable lock, or instructional DVD—this reflects the tool's purpose-driven, no-frills design philosophy.
Is the NAA Mini-Revolver worth it at $354.99?
At $354.99, the NAA Mini-Revolver is worth the investment if your operational requirement is maximum concealment in a reliable, mechanically simple platform.
You're not paying for advanced ergonomics or accessory rails. You're paying for a hand-fitted, stainless steel action with two cylinders, capable of firing two distinct cartridges—a level of mechanical redundancy uncommon in this price segment. For the specific niche of a failsafe backup, its value is defensible despite its obvious limitations as a general-purpose firearm.
Specs at a glance
Pros & cons
What works
- Weighs 4.9 oz (139g) — over 10 oz lighter than most polymer micro-compact pistols like the SIG P365.
- Includes both a .22 WMR and a dedicated .22 LR cylinder — provides immediate caliber flexibility without tools.
- Integral locking polymer grip/holster — protects the trigger and allows for secure pocket or belt clip carry.
- Stainless steel construction throughout — provides corrosion resistance critical for close-body carry.
Trade-offs
- Single-action only — requires manual cocking for every shot, increasing engagement time under stress.
- Fixed, rudimentary sights — the half-moon rear notch offers minimal precision for shots beyond 7-10 yards.
- Stiff .22 WMR recoil in a 4.9 oz frame — manageable but sharp, requiring a firm grip to maintain control.

Frequently asked questions
- Is it compatible with .22 Short ammunition?
- No, it is not compatible with .22 Short cartridges. The cylinders are chambered specifically for .22 Winchester Magnum Rimfire (WMR) and .22 Long Rifle only. Attempting to fire .22 Short will result in improper headspacing and potential ignition failures. Stick with standard-velocity .22 LR or .22 WMR from manufacturers like CCI or Federal.
- Does it fit in a standard front pants pocket?
- Yes, it fits easily in a standard front pants pocket. With the holster grip closed, the entire package is a sealed unit measuring 2.5 inches tall, 4.1 inches long, and 0.8 inches thick. This is smaller than most modern smartphones, allowing for complete concealment in jeans, dress slacks, or a jacket pocket without printing.
- How do I switch between the .22 WMR and .22 LR cylinders?
- Switching cylinders requires removing the cylinder pin, swapping cylinders, and re-seating the pin—a process that takes approximately 15-20 seconds with practice. Ensure the hammer is fully down and the cylinder rotates freely after installation. Field-strip instructions are detailed in the North American Arms owner's manual, which you should download from their website before your first range session.
- Does this work with a suppressor?
- No, the NAA Mini-Revolver is not designed for suppressor attachment. There are no threaded barrels available for this model from the factory, and the cylinder gap will always vent gas and sound, negating the effectiveness of a suppressor. If a suppressed .22 is your goal, you should look at a dedicated pistol with a threaded barrel and fixed barrel adapter for your suppressor.
