About this product
The North American Arms 50th Anniversary Mini-Revolver .22 WMR 5rd is a limited-edition, single-action pocket revolver celebrating NAA's five decades of machining ultra-compact defensive tools. This commemorative piece pairs the proven mechanical platform of the standard NAA Mini-Revolver with engraved stainless steel, black pearl grips, and a gold medallion to mark the occasion. Its 5.13-inch overall length and 5.25-ounce weight define its role as a specialized tool, not a versatile primary.
What is the North American Arms 50th Anniversary Mini-Revolver used for?
This revolver serves three primary functions: commemorative display, ultra-discreet deep concealment where legal, and as a highly specialized backup firearm. The single-action mechanism and 5.25-ounce weight make it suitable for pocket or ankle carry, but its 1.125-inch cylinder and 2-inch barrel demand practice with its diminutive fixed sights to achieve any practical accuracy beyond 7 yards.
How does the North American Arms Mini-Revolver compare to the Stevens 334 Rifle?
The NAA Mini-Revolver and the Stevens 334 Rifle occupy opposite ends of the firearm spectrum; the Stevens is a purpose-built 7.1-pound hunting rifle chambered in .308 Win, designed for accuracy at 200+ yards, while the NAA is a sub-6-ounce personal defense tool effective at contact to 7-yard distances. If you need a tool for harvesting game or precision target work, the Stevens 334 is objectively superior; if you require absolute maximum concealment in a last-resort defensive format, the NAA is the better, though limited, choice.
What does it weigh and what are the dimensions?
The revolver weighs 5.25 ounces (149 grams) unloaded, with an overall length of 5.13 inches and a cylinder width of 1.125 inches. For reference, the barrel length is precisely 2.00 inches, and the grip circumference measures approximately 3.5 inches, making it smaller than a standard credit card in profile and lighter than a modern smartphone.
Who is this NOT for?
This is not a firearm for a novice shooter, someone seeking a versatile primary carry pistol, or anyone unwilling to master its single-action manual of arms. Its tiny sights, heavy double-action-only trigger pull (courtesy of its manual cocking requirement), and potent .22 WMR recoil in a 5-ounce frame make it a poor choice for casual plinking or first-time buyers who would be better served by a more standard platform like a Stevens 555 Sporting shotgun for recreational use.
What's in the box?
You receive the revolver, its commemorative black pearl grip panel with gold medallion, a hard plastic storage case, and a numbered certificate of authenticity validating its limited-edition status. Notably, NAA does not include a cleaning rod or brush specific to the .22 caliber bore, which is a 0.224-inch diameter, so you'll need to source that separately.
Is the North American Arms 50th Anniversary Mini-Revolver worth it at $433.99?
At $433.99, this revolver commands a roughly 40% premium over the standard NAA .22 WMR model, which trades the engraving and pearl grips for a plain stainless finish. The value is entirely in its collectible, limited-run nature as a 50th-anniversary piece. As a pure shooting tool, the standard model offers identical mechanical performance for less money; as a display piece or a “carry collector's item,” this edition justifies its price for those specifically seeking the commemorative features.

Pros & cons
What works
- Weighs 5.25 oz (149g) — truly pocket-weight deep concealment.
- Limited-edition engraving and pearl grip increase collectible value over standard model.
- Stainless steel construction resists corrosion for long-term storage or carry.
Trade-offs
- Single-action only requires manual cocking before each shot — not ideal for rapid defensive use.
- Fixed sights are minimal and challenging to acquire quickly on the 2-inch barrel.
- .22 WMR produces significant muzzle flash and recoil in the 5.25-ounce frame.
- Commendable but not functional engraving adds cost over the plain $309 standard model.

Frequently asked questions
- Is it compatible with standard .22 LR ammunition?
- No, it is chambered exclusively for .22 Winchester Magnum Rimfire (.22 WMR). The cylinder is not bored for the shorter .22 Long Rifle cartridge. Attempting to fire .22 LR in this revolver is unsafe and will cause malfunctions.
- Does it fit a standard pistol safe?
- Yes, its 5.13-inch length and sub-1.5-inch width allow it to fit in virtually any pistol-sized safe compartment. For secure storage, consider a small biometric safe like a Vaultek VT10, which has an interior dimension of 8.5 x 6.5 x 2.5 inches.
- How long does shipping take to an FFL?
- Ironclad Armory processes and ships orders within 2 business days. Transit time via UPS or FedEx ground service is typically 3-5 business days to the continental US, but your chosen FFL dealer must process the transfer, which can add 1-2 days.
- Can I return it if it doesn't fit my hand?
- No, due to federal regulations, firearm sales are final once transferred through an FFL. We recommend examining the 3.5-inch grip circumference measurement carefully before purchasing. All sales are subject to our compliance verification prior to shipment.
- Does this work with a conventional holster?
- It requires a holster specifically molded for the NAA Mini-Revolver frame. Common models from dealers like DeSantis or Sticky Holsters designed for the standard NAA .22 WMR will fit this anniversary edition, as the frame dimensions are identical.
