Detailed Features 

The 2-inch barrel and 10.8 oz weight keep it compact enough for pocket carry or as a trail backup. The .22 Magnum chambering gives it more energy than .22 LR — still a mild round, but a meaningful step up. The Marble Arms adjustable sights are a genuine improvement over fixed sights at this size, letting you adjust for elevation and windage. Safety cylinder slots and a half-notch hammer system allow safe loaded carry. The oversized rubber grip handles recoil better than the standard boot grip and gives you more to hold onto during firing. 
 
As with all NAA revolvers, this is single-action — cock the hammer before every shot. The trigger pull is clean as a result. 
 

Usage Scenarios 

• Concealed carry backup: At 10.8 oz and under 6 inches, it fits where larger guns won't. 
• Trail carry: .22 Magnum covers small animal pests and snake defense at close range. 
• Range plinking: Low recoil, cheap ammo, and the adjustable sights make it reasonably enjoyable to shoot for groups.

The NAA Black Widow in .22 Magnum is one of the more capable options in the NAA lineup. The .22 WMR chambering and 2-inch barrel step it up from the basic Mini-Revolver, and the adjustable Marble Arms sights are a practical upgrade that owners consistently mention.

The stainless construction and overall build quality get positive reviews. Most owners find it durable and reliable, and the oversized rubber grip makes it easier to control than the smaller-framed NAA revolvers.

Stopping power debate is inevitable with any .22 caliber. Some owners view the .22 Magnum as marginal for serious defense use and carry it as a backup to something larger. Others treat it as a primary carry where concealability is the priority and a larger gun isn't practical. Both positions are reasonable and both come up in discussions.

The trigger pull runs heavier than some expect for a single-action mechanism. Accuracy at close range is solid; at distance it gets harder, which is expected from a 2-inch barrel. Price is generally considered fair for the quality and brand reputation. Overall, it's a well-executed compact revolver for buyers who understand what they're getting.
