The Redhawk is the first large-bore double-action revolver introduced by Ruger. It was designed by Roy Melcher and Harry Sefried. Sefried previously worked for High Standard Manufacturing Company, where he designed the High Standard Sentinel revolver.

Announced in 1979, the Redhawk began shipping to customers in 1980, and was chambered in .44 Magnum caliber. The revolver featured a square butt grip, adjustable sights, and 5.5- and 7.5-inch barrel lengths, and was available in blue or stainless steel finishes. While the grip profile and no-sideplate construction of the Redhawk was similar to that of the earlier Ruger Security-Six, it was in fact a new design, incorporating a much larger and heavier frame.

Designed for use with the heaviest .44 Magnum loads, the Redhawk included a triple lock, where the cylinder is locked in place at front, rear, and bottom (a feature previously found solely on Smith & Wesson's triple lock .44 Hand Ejector design, out of production since 1915). Sefried himself observed that the triple lockup design "would last almost indefinitely". To simplify the design and cut the number of parts, the Redhawk used a single coil spring to power both hammer and trigger, resulting in a slightly heavier trigger pull in single action mode. Because of the single power spring, Redhawk revolvers typically show little disparity between single and double-action pull weights - often three pounds or less in variation.

The revolver has forward ramp sights with four different interchangeable sight inserts. The rear sights are fully adjustable, featuring a white outline. The Redhawk is available with scope mounts and rings. The Redhawk holds six or eight cartridges depending upon caliber, and has been produced with 4-inch, 4.2-inch, 5.5-inch, and 7.5-inch barrels.
