The Blackhawk in .45 Colt at 4.62-inch barrel length is the traditional Cavalry configuration for the most historically significant American revolver cartridge. The Ruger Blackhawk's overbuilt frame allows .45 Colt handloads that far exceed standard SAAMI pressures — what the handloading community calls "Ruger-only loads." This configuration is a practical hunting and outdoor gun.
