Ruger Blackhawk

The Ruger Blackhawk is a six-shot, single-action revolver manufactured by Sturm, Ruger & Co. of the United States and introduced in 1955 as a modern centerfire alternative to the discontinued Colt Single Action Army. Originally chambered in .357 Magnum, it has since been offered in multiple calibers, finishes, and barrel lengths from 4 5/8 inches to 7 1/2 inches, with adjustable rear sights rather than the Colt's fixed sights and wire coil springs in place of flat leaf springs for greater durability. The 1973 New Model variant added a transfer bar safety mechanism, removing the need to carry the revolver half-cocked for safe loading and unloading, and more than 2 million Blackhawks have been produced, making it one of Sturm Ruger's most successful products.
