The Ruger Blackhawk was Bill Ruger's modern single-action revolver, chambered in .357 Magnum and featuring a coil-spring action rather than the traditional flat-spring SAA mechanism. It offered the rugged, simplified single-action handling that western enthusiasts loved combined with modern safety features including a transfer bar safety added in 1973. The Blackhawk is the practical working single-action — strong, reliable, and available in powerful calibers the SAA cannot handle.
