I’ve had my hands on a lot of mini revolvers over the years, and the NAA Black Widow Mini Revolver .22 WMR 2″ 5-Round Stainless is one that always makes me smile. It’s a pocket powerhouse that disappears in a jeans pocket but still delivers enough punch for a backup gun or a trail companion. Let’s break down what makes this little snake charmer tick.

Key Features

• 2″ Heavy Vent-Rib Barrel – Why it matters: The vent rib reduces heat mirage and adds rigidity for better accuracy at typical self-defense distances, while the heavy profile tames muzzle flip in a tiny package.
• Oversized Black Rubber Grips – Why it matters: These wrap-around grips give you a full three-finger hold on a frame that normally fits two fingers, reducing felt recoil and improving control during rapid fire.
• Five-Shot Bull Cylinder – Why it matters: The fluted cylinder is beefed up to handle the higher pressure of .22 WMR loads, giving you five rounds of rimfire magnum punch in a package smaller than your wallet.
• Marble Arms Fixed Sights – Why it matters: Low-profile and snag-free, these sights are drift-adjustable for windage and sit flush with the top strap, so they won’t hang up on a pocket or holster draw.
• Exposed Hammer with Half-Cock Safety – Why it matters: The traditional single-action hammer lets you carry with an empty chamber under the hammer and load five in the cylinder, then cock and fire when needed—a proven carry method for mini revolvers.

Who It’s For

This revolver is for the collector who appreciates the engineering behind a mini gun that actually shoots straight. It’s also for the gun show regular who wants a backup piece that rides in a boot, a vest pocket, or a belt pouch without printing. If you carry a full-size 1911 or a Glock 19 as your primary, the Black Widow is the perfect deep-concealment or ankle backup. It’s also a fantastic trail gun for plinking or finishing small game, thanks to the .22 WMR’s flat trajectory and energy retention.

Pros and Cons

Pros: Disappears in any pocket, stainless finish resists rust, .22 WMR is potent for its size, vent-rib barrel improves sight picture, rubber grips make it shootable.

Cons: Single-action only means you must manually cock the hammer for each shot—no rapid double-action trigger pulls. The fixed sights are basic and not night sights, so low-light shooting is a challenge.

Comparison: NAA Black Widow vs. Ruger LCR .22 WMR vs. S&W 351C .22 WMR

Feature	NAA Black Widow	Ruger LCR .22 WMR	S&W 351C .22 WMR
Action	Single-action revolver	Double-action revolver	Double-action revolver
Capacity	5 rounds	8 rounds	7 rounds
Weight	6.3 oz	13.5 oz	11.1 oz
Barrel length	2″	1.875″	1.875″
Overall length	5.25″	6.50″	6.31″
MSRP	$308.77	~$580	~$650

The NAA Black Widow is significantly lighter and smaller than either the Ruger LCR or the S&W 351C, making it the best choice for pocket carry. The Ruger and S&W offer double-action triggers and higher capacities, but they weigh nearly twice as much and cost almost double. If you prioritize concealability and price, the Black Widow wins. If you want a faster trigger and more rounds, look at the other two.

FAQ

What is the barrel length on the NAA Black Widow .22 WMR?

The barrel is 2 inches long, measured from the forcing cone to the muzzle. It features a heavy vent-rib profile for improved heat dissipation and sight alignment.

Does the NAA Black Widow have a safety?

Yes. The revolver has a half-cock safety notch on the hammer. When the hammer is in the half-cock position, the cylinder rotates freely and the hammer cannot contact the firing pin. This is the standard carry method for single-action mini revolvers.

Can the NAA Black Widow shoot .22 LR?

No. This model is chambered specifically for .22 Winchester Magnum Rimfire (.22 WMR). Using .22 LR in a .22 WMR chamber can cause case rupture due to the difference in case length and pressure. You would need the NAA Black Widow in .22 LR for that.

What grips come on the NAA Black Widow?

The revolver ships with oversized black rubber grips that extend below the frame to give you a full three-finger hold. These are standard on the Black Widow model and are not interchangeable with the smaller NAA grips, but you can swap them for custom wood or laminate grips from NAA or aftermarket sources.

Is the NAA Black Widow good for concealed carry?

Absolutely. At 6.3 ounces and 5.25 inches overall length, it’s one of the smallest .22 WMR revolvers on the market. It fits in a jeans watch pocket, a vest pocket, or an ankle holster with zero printing. The single-action trigger and fixed sights are simple and reliable, making it a solid backup or deep-concealment gun.
