North American Arms SWC250 Sidewinder 22 LR/WMR 2.5" Barrel 5rd

The North American Arms SWC250 Sidewinder delivers exceptional versatility with dual caliber capability in a compact stainless steel package. This mini-revolver features an innovative swing-out cylinder design that sets it apart from traditional NAA break-top models. The rosewood birdshead grip provides enhanced control while maintaining the ultra-compact profile that makes NAA revolvers ideal for deep concealment carry.

What Makes This Different

The Sidewinder's swing-out cylinder mechanism eliminates the need to remove the cylinder pin for loading and unloading, significantly reducing reload time compared to standard NAA models. This design incorporates a spring-loaded ejector system that automatically pushes spent cases clear of the cylinder chambers. The dual caliber capability allows shooters to switch between 22 LR and 22 WMR cartridges using the included conversion cylinder, providing flexibility for different applications and ammunition availability.

Key Features

• Swing-out cylinder with spring-loaded ejector for faster reloads
• Dual caliber system with included 22 LR and 22 WMR cylinders
• 2.5-inch stainless steel barrel with micro front sight
• Rosewood birdshead grip for improved handling and control
• Overall stainless steel construction resists corrosion
• 5-round cylinder capacity in both calibers
• Single-action trigger mechanism with half-cock safety notch

The SWC250 maintains the reliability NAA revolvers are known for while addressing the loading limitations of traditional models. The 22 WMR cylinder delivers significantly more power than 22 LR, making it suitable for small game hunting and pest control at extended ranges. The compact 5.75-inch overall length and lightweight construction make it practical for backup carry or situations requiring minimal printing. Weather resistance comes from the all-stainless construction, while the fixed sights provide adequate accuracy for typical mini-revolver engagement distances.
