NAA SIDEWINDER 22LR/22WMR 4″ – SWINGOUT CYLINDER S/S MAT WOO

NAA's Sidewinder is a 5-shot, dual-caliber mini revolver with a swing-out cylinder and a 4-inch barrel — a configuration that stands apart from the brand's fixed-cylinder pocket revolvers. It draws collectors, rimfire enthusiasts, and backcountry handgun carriers who want the convenience of a swing-out cylinder in a compact stainless package. TacticCAL carries it as a CA-legal purchase under the PC §32100 single-action revolver exemption.

Swing-Out Cylinder, Dual-Caliber Setup: Who This Configuration Serves

The Sidewinder's swing-out cylinder is the defining feature here — NAA built it into a platform that still runs both .22 LR and .22 Magnum via a conversion cylinder. The 4-inch barrel gives this more reach than the brand's sub-2-inch pocket models, making it a reasonable choice for trail carry, small-game use, or a dedicated rimfire collection piece. Matte stainless finish and rosewood bird's head grips make it a practical-yet-distinctive carry option. Fixed sights keep the manual of arms simple. Buyers who want to run both calibers will want to stock both .22 LR and .22 WMR — Federal and Speer both offer solid options in each. CA-legal under PC §32100.

Frequently asked questions

What does the .22 LR conversion cylinder actually mean in practice — do I need two separate revolvers?

No. The Sidewinder ships with both a .22 WMR cylinder and a .22 LR conversion cylinder, per the manufacturer description. You swap cylinders to change calibers. It's one revolver running two rimfire cartridges — useful for cost-conscious range sessions with .22 LR and field use with .22 Magnum.

Is the 4-inch Sidewinder practical for trail or backcountry carry given its compact frame?

The compact frame and 4.25-ounce weight make it light enough for pocket or belt carry on the trail. The 4-inch barrel and .22 Magnum capability give it more utility than the shorter NAA models. A Galco or Safariland belt holster sized for compact revolvers is worth sourcing before pickup.

I'm ready to start the purchase process — what do I need to bring to TacticCAL?

Bring your valid government-issued ID and your Firearm Safety Certificate — the FSC must be in hand before the DROS transaction begins. After the paperwork is submitted, California's 10-day waiting period starts. Use that time to source .22 LR and .22 WMR ammunition and a CA-compliant locked transport container for the drive home.

What do I need to bring for DROS in California?
