The Ruger Hawkeye is a single-shot pistol chambered for the .256 Winchester Magnum cartridge, produced by Sturm, Ruger &amp; Co. from 1963 until July 1964. It was built on the same frame as the Ruger Blackhawk, but rather than having a rotating cylinder like a standard revolver, it featured a swiveling breechblock which allowed an individual round to be loaded and sealed into the frame.
The Ruger Hawkeye pistol was not a commercial success, and was discontinued after only 3,075 were produced.
