Detailed Features 

 
At 0.6 lbs and 5.88 inches overall, this is a genuinely small revolver. The single-action mechanism requires manually cocking the hammer before each shot. Marble Arms fixed sights provide consistent aiming without the complexity of adjustable rear sights. The Matte Black finish with Stainless Cerakote on key components resists corrosion and wear. 
 
The finger-grooved rubber grip improves retention for a small-frame revolver. The .22 WMR caliber delivers more energy than standard .22 LR from the short barrel.

The NAA Black Widow draws a specific crowd: people who want an ultra-compact backup gun or pocket carry option in .22 WMR. The size and weight are the most cited positives. At 0.6 lbs, it adds almost nothing to a carry load, and the 5.88-inch overall length makes it genuinely concealable in a pocket or ankle holster.

Build quality gets consistent praise. Owners describe it as solid and well-made for its size. The Matte Black finish with Cerakote holds up well to regular carry conditions. The .22 WMR cartridge's performance from a 2-inch barrel is more capable than .22 LR, though capacity is the persistent concern with only 5 rounds available.

The single-action mechanism and fixed sights draw criticism. The hammer must be cocked manually before each shot, which slows follow-up shooting. Some owners find the fixed sights limiting at anything beyond very short range. Trigger pull weight opinions vary — manageable for some, heavy for others in rapid-fire situations.

Most buyers understand the trade-offs going in. The Black Widow occupies a specific niche, and owners who bought it for that niche are generally satisfied.
