Detailed Features 

The stainless construction resists corrosion, which matters for a gun that rides in a pocket or on a belt all day. The Viridian laser grip aids target acquisition in dim conditions without requiring a separate mount. The safety cylinder includes half-notch capability, allowing safe carry between shots -- standard practice on single-action revolvers. Marble Arms fixed sights are accurate out of the box with no adjustment needed. 
 

Usage 

The Black Widow works as a backup carry piece or a trail gun where size and weight are the primary constraints. It's concealable in situations where a full-frame pistol isn't practical. The .22 WMR gives it more energy than .22 LR at the cost of recoil that's still quite manageable from an 8.8 oz gun. Range use is viable for familiarization, though the five-round capacity and single-action requirement make it a deliberate shooter rather than a fast one.

Owners of the NAA Black Widow in .22 WMR generally buy it knowing exactly what it is -- a backup gun or deep-carry option where a larger pistol isn't an option. That context shapes most of the feedback.

The compact size and low weight are the most consistent positives. People who carry it as a backup or in situations where other guns are impractical find it fills that role reliably. The Viridian laser grip is well-regarded for making the short sight radius more workable, particularly under stress.

The five-round capacity is the most common criticism, and it's a real limitation compared to even the smallest pocket pistols. Some users also find the trigger pull heavier than expected for a single-action design, which can affect accuracy until you adjust. Feeding issues with certain ammunition brands come up occasionally.

The overall picture is a gun people are generally satisfied with for its specific niche. It's not trying to compete with a full-size defensive pistol -- it's a last-resort or supplemental carry option that fits where nothing else will.
