Description
North American Arms took everything people like about their classic .22 Magnum mini revolver frame and beefed it up into something you can genuinely shoot well. The Black Widow keeps the same tiny footprint, right around 5.9 inches long and under 9 ounces, but adds a 2-inch heavy vent barrel and a bull cylinder that give the little gun some real steadiness in the hand. Toss in the oversized black rubber grips with their signature red hourglass and you get a mini revolver that fills your palm instead of disappearing in it.
Why the Black Widow Shoots Better Than Its Size
Most pocket-sized rimfires make you fight for a decent sight picture. This version of the Black Widow ships with Marble Arms adjustable sights, so you can tune elevation to match whatever .22 WMR load you settle on. That matters more than you might think with magnum rimfire, since point of impact can shift noticeably between 30, 40, and 45 grain loads. The extra barrel and cylinder weight up front also helps tame the snap, and the finger-friendly rubber grips give you enough purchase to run it confidently.
Built the NAA Way
The frame and cylinder are stainless steel, the action is a simple single action that requires the hammer to be cocked for every shot, and the cylinder features NAA's safety notches milled between the chambers. Rest the hammer in a notch and you can carry all five chambers loaded with the hammer sitting on solid steel instead of a cartridge rim. It is a proven, mechanically simple design that NAA has been refining for decades.
Where the Black Widow .22 WMR Fits
This is a deep concealment piece, a backup to your primary, or a lightweight companion for the tackle box, trail, or camp. It rides in a pocket without printing, weighs less than most folding knives feel like by the end of a long day, and delivers five rounds of .22 Magnum when a bigger gun just is not practical to have along. For a lot of folks, that combination is exactly why these little revolvers have such a loyal following.

Frequently Asked Questions
Does this Black Widow come with a .22 LR conversion cylinder?
No, the NAA-BWMA is the .22 Magnum only version and ships with a single .22 WMR bull cylinder. If you want to shoot both cartridges, NAA offers the convertible model (NAA-BWCA) that includes both a .22 WMR and a .22 LR cylinder. Double check the model number before you buy so you get the setup you want.
Can the NAA Black Widow be carried with all five chambers loaded?
Yes. NAA mills safety notches between the chambers on the cylinder, so you can lower the hammer into a notch and it rests on solid steel rather than a live cartridge rim. That lets you safely carry a full five rounds, which is one of the smartest features on these mini revolvers.
How adjustable are the sights on this model?
The Black Widow with adjustable sights uses a Marble Arms sight set that adjusts for elevation. That lets you fine-tune your point of impact for a specific .22 WMR load, which is handy since bullet weights in magnum rimfire vary quite a bit. It gives this little revolver noticeably more practical accuracy than fixed-sight pocket guns.
Is the recoil manageable in a revolver this small?
It is more comfortable than most people expect. The heavy vent barrel and bull cylinder add weight up front, and the oversized rubber grips give your hand something real to hold onto. Even recoil-sensitive folks tend to find .22 Magnum out of this platform easy to manage, with more bark than bite.
