Key Features
- Dual-Caliber Versatility — Comes with a .22 WMR cylinder and a separate .22 LR cylinder. Why it matters: you can train cheap with .22 LR and carry .22 Magnum for defense or varmint hunting, all in one revolver.
- Swing-Out Cylinder — Unlike most mini-revolvers, the Sidewinder has a swing-out cylinder for faster reloads. Why it matters: you spend less time fumbling with a loading gate, which matters when seconds count in a self-defense scenario.
- 4″ Stainless Barrel — The 4″ barrel gives you a longer sight radius and better velocity than shorter mini-revolver barrels. Why it matters: you get more accuracy and terminal performance from .22 WMR, especially at 25+ yards.
- Rosewood Bird’s-Head Grips — Classic rosewood grips with a bird’s-head profile that fits the hand naturally. Why it matters: you get a secure, comfortable grip that helps control muzzle flip and keeps the revolver on target.
- All-Stainless Construction — Frame, barrel, and cylinder are stainless steel. Why it matters: this revolver resists rust and corrosion, so it holds up to sweat, rain, and humid carry conditions.
Who It’s For
The NAA Sidewinder is for CCW holders who want a backup gun that won’t print. It’s also for hikers, campers, and hunters who need a lightweight trail gun for small game and emergency defense. If you’re looking for a pocket-friendly revolver with two caliber options and faster reloads than traditional mini-revolvers, this fits.
Pros & Cons
- Pros: Dual-cylinder system saves you from buying a second gun; swing-out cylinder beats loading gate mini-revolvers for speed; stainless steel is low-maintenance; 4″ barrel gives better accuracy than 1″ or 2″ models.
- Cons: Single-action trigger requires manual cocking, which is slower than double-action; .22 WMR has less stopping power than .38 Special or 9mm, so shot placement is critical.
Comparison
| Feature | NAA Sidewinder 4″ | Ruger LCR .22 WMR | Smith & Wesson 351C .22 WMR |
|---|---|---|---|
| Barrel Length | 4″ | 1.87″ | 1.875″ |
| Weight (empty) | 7.5 oz | 13.5 oz | 11.2 oz |
| Capacity | 5 rounds | 8 rounds | 7 rounds |
| Action | Single-action | Double-action | Double-action |
| MSRP | $539.76 | ~$650 | ~$700 |
The Ruger LCR and S&W 351C are both double-action revolvers with better sights and higher capacity. But the Sidewinder is lighter, has a longer barrel for better velocity, and costs less. The trade-off is the single-action trigger, which is slower in a rapid-response situation.
FAQ
Is the .22 LR cylinder included with the NAA Sidewinder 4″?
Yes. The Sidewinder ships with both a .22 WMR cylinder and a .22 LR conversion cylinder. You can switch between them by removing the cylinder pin and swapping cylinders—no tools required.
How do you reload the NAA Sidewinder?
The Sidewinder uses a swing-out cylinder. Press the cylinder release button on the left side of the frame, swing the cylinder out, eject spent casings with the push of the ejector rod, load fresh rounds, and close the cylinder.
Is the NAA Sidewinder legal for concealed carry?
Laws vary by state and locality. The Sidewinder is a single-action revolver under 8″ overall length, so check your local carry laws. In most states, it qualifies as a handgun for concealed carry if you have a valid permit.
Can the NAA Sidewinder handle .22 WMR +P ammo?
No. North American Arms does not recommend +P or high-pressure .22 WMR loads in the Sidewinder. Stick to standard-velocity .22 WMR ammunition to avoid damaging the cylinder or frame.
