The Sidewinder is the only NAA mini revolver with a swing-out cylinder. Every other NAA Mini — the base NAA Mini Revolver, the Pug, the NAA Black Widow — uses a removable cylinder pin and requires disassembly to reload. The Sidewinder uses a side-swing cylinder release that lets you dump cases and reload in seconds rather than minutes. That single mechanical difference is the entire reason this variant exists.

At 6.7 oz with a 1.5" barrel and 5" overall length, it sits between the standard Mini Revolver and the Black Widow in size and weight. The Mini's bird's head rosewood grip and 5-shot cylinder carry over. The swing-out cylinder uses a manual extractor rod — owners pop the cylinder open, push the rod to eject cases, drop fresh rounds into the chambers, and snap the cylinder closed. Total reload time with practice is well under 30 seconds compared to multiple minutes for the cylinder-pin NAA variants. The trade is mechanical complexity: the Sidewinder has more moving parts than the simpler cylinder-pin design and a few more potential wear points.

The swing-out cylinder is a relatively recent addition to the NAA lineup compared to the 1976-origin original. NAA introduced it specifically to address the most consistent owner complaint about the mini revolver platform: that reloading was so slow it made the second cylinder of ammunition effectively unavailable in any defensive scenario. The Sidewinder doesn't change the fundamental contact-distance use case of a 6.7 oz revolver, but it makes a second cylinder of ammo actually accessible in a way no other NAA mini does.
