The Ruger Single Seven is a 7-shot single-action revolver chambered in .327 Federal Magnum. The 4.62-inch barrel is the shorter of two offerings. The .327 Federal Magnum produces ballistics approaching .357 Magnum in a smaller case, and seven rounds in the cylinder gives it more capacity than a .357 single action. Chambers also accept .32 H&R Magnum and .32 S&W Long.
