The .45 Colt Redhawk handles the classic cartridge at pressures far exceeding SAAMI standards for older single-action revolvers. Ruger's strong frame permits handloads that approach .44 Magnum energy levels — the origin of "Ruger Only" loads. The 4.2-inch barrel is the primary configuration. Some versions are compatible with .45 ACP using moon clips.
