North American Arms Sidewinder SW4 22 WMR Revolver, 4" Barrel

In the realm of compact firearms, the Sidewinder stands as a testament to meticulous craftsmanship and practical design. This mini-revolver is engineered with a swing-out cylinder—a feature that facilitates swift reloading without necessitating removal of the cylinder itself. Such innovation marks it as an ideal choice for those seeking efficiency in their shooting experience.

The construction begins with an investment casting frame, ensuring robustness and reliability. Both barrel and cylinder are expertly machined from solid stainless steel bar stock, allowing for precision that meets exacting standards necessary for this diminutive yet formidable firearm.

Aesthetically, the fit and finish are exemplary. The polished surfaces of the cylinder and sides contrast beautifully with the matte finish on strategic areas like the topstrap, barrel sides, backstrap, and bottom of the frame—resulting in both visual appeal and reduced glare during use.

Designed as a five-shot revolver chambered in .22 Magnum, its single-action-only mechanism features an exposed hammer paired with an unguarded trigger—a nod to classic simplicity. Its bird's-head grip profile mirrors other models within its category but accommodates various optional stocks for personalized comfort.

Functionality takes precedence with thoughtful internal mechanics; notably, due to its design specifics—the Sidewinder opens rightward upon setting the hammer at half-cock position. Engaging this mechanism involves pushing forward on a knurled ejection rod tip to unlock and swing open the cylinder effortlessly.

Once opened, partially eject spent cases by depressing the ejector rod; however, manual removal remains essential given spatial constraints inherent to such compactness—requiring rotation of cylinders between each extraction cycle.

With attributes including a 4-inch barrel length finished in matte stainless steel complemented by rosewood grips—and measuring an overall length of 7.75 inches—the Sidewinder embodies both elegance and functionality.
