NAA Black Widow .22 WMR 2-inch 5-Round Adjustable Sights
About this product
What is the NAA Black Widow .22 WMR 2-inch 5-Round Adjustable Sights revolver? It's a stainless steel single-action mini-revolver chambered in .22 Winchester Magnum, designed for deep concealment and backup use where traditional firearms won't fit. Built on NAA's proven mini-frame with a 2-inch heavy-vent barrel and adjustable Marble Arms sights, this 8.8-ounce package delivers five rounds of .22 WMR in a footprint smaller than most smartphones.
What is the NAA Black Widow .22 WMR used for?
The Black Widow serves one primary function: to disappear into your daily carry routine when nothing else will. This revolver fits front pocket holsters that reject even subcompact semi-autos like the Glock 43, making it ideal for summer attire, administrative professionals restricted by workplace policies, and as a secondary for uniformed personnel who can't easily access their primary weapon. The single-action operation means you won't be clearing double-feeds or worrying about magazine springs, though the 8.8-ounce weight requires deliberate practice to master consistent trigger control.
How does the NAA Black Widow compare to the North American Arms .22 LR Mini-Revolver?
The Black Widow's advantage over NAA's standard .22 LR mini-revolver comes down to terminal ballistics and sighting. Where the .22 LR version fires lightweight rounds ideal for pest control, the Black Widow launches 40-grain .22 WMR bullets at approximately 1,000 fps from its 2-inch barrel — nearly double the energy of standard .22 LR. The Marble Arms adjustable sights provide elevation correction, while the standard models use fixed gutter sights that can't compensate for ammunition variations. For deep concealment requiring defensive capability rather than plinking, the Black Widow is objectively better, though its 8.8-ounce weight is 2.3 ounces heavier than the 6.5-ounce .22 LR model.
What does it weigh and what are the dimensions?
The revolver's 8.8-ounce unloaded weight distributes across a stainless steel frame measuring 4.75 inches overall length with a 2-inch heavy-vent barrel. The cylinder diameter is 1.19 inches, while grip width reaches 1.12 inches at the widest point of the rubber panels. Those dimensions allow it to fit nearly any front pocket holster designed for mini-revolvers, though the 6-inch overall height when measured from top of sight to bottom of grip matters for certain concealment configurations.
Who is this NOT for?
Skip the Black Widow if you're looking for a primary defensive firearm or need capacity beyond five rounds. This isn't a Stevens 334 Rifle in .308 Win — you won't be making ethical 200-yard shots on game. Avoid it if you have hand strength limitations, as the single-action hammer requires deliberate thumb-cocking that can challenge arthritic shooters. And if your carry environment demands rapid follow-up shots during stress, the Black Widow's 5-round cylinder and reload process makes it objectively inferior to modern semi-autos with 10+ rounds and magazine-swap speed.
What's in the box?
You'll receive the revolver itself with factory-installed Marble Arms adjustable sight, one five-round cylinder for .22 WMR ammunition, two oversized black rubber grip panels, and the standard NAA safety card and owner's manual. Unlike some competitors, Ironclad Armory doesn't include a holster or cleaning kit — you'll need to purchase those separately if you want immediate carry capability. The packaging typically includes a small hex key for sight adjustments, though some users report needing a 1.5mm Allen wrench for finer tuning after the sight's initial zeroing.
Is the NAA Black Widow worth it at $342.99?
At $342.99, the Black Widow justifies its price through two factors you can't get elsewhere: legal compliance and mechanical simplicity. In jurisdictions restricting semi-automatic carry or regulating magazine capacities, this revolver's five-round cylinder and single-action operation often bypass otherwise prohibitive regulations. The stainless steel construction and adjustable sights represent a tangible upgrade over cheaper pot-metal mini-revolvers that can't handle .22 WMR pressure cycles. Compared to other backup options in this price range, you're paying for concealability that even a Stevens 555 Sporting 20 Gauge can't match, though you're sacrificing defensive capability accordingly.

Frequently asked questions
- Is the .22 WMR Black Widow compatible with .22 LR ammunition?
- No, the Black Widow is specifically chambered for .22 Winchester Magnum Rimfire (WMR) cartridges only. Attempting to fire .22 Long Rifle through this revolver can cause dangerous pressure spikes and cylinder damage. The cylinder chambers measure 0.242 inches at the rim, while .22 LR cartridges measure approximately 0.226 inches — that dimensional mismatch creates significant safety risks.
- Does this fit standard front pocket holsters?
- Yes, the Black Widow's 4.75-inch overall length and 1.12-inch grip width fit most NAA-specific leather or kydex pocket holsters. For reference, it's compatible with DeSantis Nemesis pocket holsters (model N36BG) and Sticky Holsters MD-4 size configurations. The revolver's 8.8-ounce weight won't sag most pocket materials, though heavier fabrics like denim provide better concealment than lightweight dress pants.
- How long does shipping take to Montana?
- Ironclad Armory processes most orders within 2 business days, with ground shipping via UPS requiring 5-7 additional days to reach Montana addresses. For expedited delivery, we offer 2-day air shipping through FedEx for an additional $24.95 — firearms ship to your selected FFL dealer, not directly to residential addresses, per federal regulation.
- Can I return it if it doesn't fit my hand?
- No, firearms sales are final under Ironclad Armory's policy once the transfer occurs at your FFL dealer. We recommend handling similar NAA models at local dealers before purchasing, as grip dimensions affect control significantly with 8.8-ounce revolvers firing .22 WMR. The oversized black rubber grips measure 1.12 inches at their widest point — compare that to your handspan before completing the transaction.
- Does this work with aftermarket laser sights?
- No, the Black Widow lacks rail mounting systems for accessories like Crimson Trace laser grips or Picatinny-mounted optics. The frame design accommodates only the factory-installed Marble Arms adjustable sights — any modifications would require gunsmithing that voids NAA's lifetime warranty. For laser-capable mini-revolvers, consider NAA's Sidewinder model with built-in mounting points.
