Classic Lines, Classic Feel, Modern Features.  The Ruger® New Model Blackhawk® is the most advanced single-action revolver ever made.  While retaining the solid frame, feel and comfortable grip of the classic single-actions, they feature Ruger’s patented transfer bar ignition system with loading gate interlock, an all-coil spring mechanism, adjustable sights, and frame-mounted firing pin.  New Model Blackhawk revolvers have earned a reputation as the best value on the market due to their durability and affordability. Convertible models come equipped with an extra cylinder and are popular with shooters who appreciate the classic single-action revolver but opt for the versatility of being able to use more than one caliber in their handgun.  With its interchangeable cylinder, Convertible models can be easily converted from one caliber to another without the use of tools.  This versatility allows avid shooters of autoloading pistols to enjoy shooting a classic American single-action sidearm with their favorite pistol cartridge.
