North American Arms marks five decades of precision mini-revolver manufacturing with the NAA 50th Anniversary Mini-Revolver .22 WMR 5rd Stainless — a limited-edition single-action that blends collector-grade engraving with genuine pocket-pistol utility. Chambered in .22 Winchester Magnum, this five-shot revolver delivers rimfire stopping power in a package small enough to disappear into a jeans watch pocket or ankle rig. The scroll engraving and laser-etched anniversary markings make it a conversation piece at the range, but the stainless-steel build and proven NAA action mean it’s ready for discreet carry when you need a backup that won’t print.

Key Features
- Engraved 50th Anniversary Scrollwork — Each revolver features laser-etched scrollwork and a commemorative marking on the barrel shroud. Why it matters: You get a limited-edition collectible that holds value while still functioning as a working firearm.
- Single-Action .22 WMR Performance — The .22 Winchester Magnum round exits at roughly 1,200 fps from this 1.6-inch barrel. Why it matters: That velocity translates to reliable expansion from quality defensive loads, giving you a rimfire option that doesn’t sacrifice terminal ballistics.
- Five-Shot Stainless Cylinder — Machined from solid stainless steel, the cylinder indexes positively with each cock of the hammer. Why it matters: You get consistent ignition and easy loading/unloading without the rust worries of blued steel in a pocket or purse.
- Compact 5.3-Ounce Build — At just over five ounces, this revolver disappears in a front pocket or a minimalist holster. Why it matters: When you can’t carry a full-size frame, this mini-revolver stays on you every day — no excuses.
Who It’s For
This revolver is built for the urban carrier who wants a last-ditch backup that’s more capable than a .22 Short but smaller than a .38 snub. It’s also a natural fit for collectors who appreciate NAA’s history — only a limited number of these anniversary models exist. Apartment dwellers will appreciate the reduced overpenetration risk compared to 9mm, making it a viable nightstand gun when paired with .22 WMR hollow points.
Pros & Cons
- Pro: True pocket carry — fits in a coin pocket or small holster without printing.
- Pro: Commemorative engraving adds collector appeal without raising the price into custom territory.
- Con: Single-action only — you must manually cock the hammer for each shot, which slows follow-up speed under stress. The short sight radius also limits practical accuracy beyond 15 yards.

FAQ
What is the cylinder capacity of the NAA 50th Anniversary Mini-Revolver?
It holds five rounds of .22 Winchester Magnum Rimfire (.22 WMR). The cylinder is fluted stainless steel and loads via a rotating gate on the right side of the frame.
Is this revolver safe to carry with the hammer on a live round?
NAA mini-revolvers are designed for carry with the hammer down on an empty chamber. The manual recommends loading five, leaving the chamber under the hammer empty, then lowering the hammer. This prevents accidental discharge if the hammer is struck.
Does the anniversary model come with a holster or box?
It ships in a commemorative NAA box with a foam insert and a basic belt-clip holster. The holster is functional but many owners upgrade to a pocket holster for better retention.
Can I use .22 Long Rifle in this revolver?
No — this revolver is chambered specifically for .22 WMR. .22 LR cases are shorter and will not headspace correctly, leading to misfires or stuck cases. Stick to .22 WMR only.
