Detailed Features 

 
Single-action operation requires manually cocking the hammer for each shot. The cylinder/half notch safety system is NAA's standard carry-safe mechanism for this platform. Fixed Marble Arms sights are small but defined. The stainless steel frame resists corrosion and gives the gun a solid feel despite its small size. Black rubber grips provide a better hold than the optional bird's-head grips for most hands. 
 
At 5.8 inches overall and under 9 oz, it's one of the smallest centerfire-capable carry options available.

The Black Widow generates consistently positive sentiment among buyers who know what they're buying — a niche, pocket-sized backup revolver — and mixed reactions from those expecting a primary carry gun.

The compactness is the defining feature and draws regular praise. The stainless steel finish earns credit for durability and feel. The .22 WMR caliber is well-regarded for close-range use, and most owners report the gun runs reliably. Shooters are often surprised by the accuracy at close range given the 2-inch barrel. The single-action mechanism and simple operation appeal to those who prefer mechanical simplicity.

Common criticisms: the 5-round capacity is low compared to semi-automatics, and the single-action operation is slower to fire. Holster options are limited, though specialized options exist. Some users mention wanting adjustable sights for improved precision. Price-to-value discussions are generally favorable given the quality and niche purpose, though some compare it unfavorably to more versatile firearms in the same price range.
