In the early 1950s, Westerns were popular in movies and television. Colt had discontinued the iconic Single Action Army prior to World War II, and few single-action revolvers were available to meet market demand for cowboy-style revolvers. In 1953, the new firm of Sturm, Ruger and Company introduced the Ruger Single Six, a .22 LR rimfire single-action revolver. The Single Six proved to be a popular seller, leading Ruger to develop and market a center-fire revolver similar to the Colt Single Action Army: the Ruger Blackhawk.
Ruger introduced the Blackhawk in 1955. Chambered for the .357 Magnum, the Blackhawk was a simple and strong design, and sold well. In 1956, as Smith & Wesson was introducing the new .44 Magnum, Ruger quickly developed a variant of the Blackhawk in the new cartridge. Ruger achieved wide popularity with this firearm in a hotly anticipated new cartridge, which was both cheaper and more readily available than the Smith & Wesson Model 29 revolver. According to popular legend, Ruger was able to field a .44 Magnum revolver at nearly the same time as Smith & Wesson due to a Ruger employee finding expended .44 Magnum cartridge cases at a scrapyard, and deducing that Smith & Wesson was about to launch a new cartridge.
The 1955–1962 Blackhawks are known today as the Flattop models, because their adjustable rear sights were not protected by "ears" extending up from the frame as later became standard. From 1962 through 1972, Ruger made the "Three Screw" Blackhawk in various calibers, so called by the number of screws visible on the side of the revolver.
The Flattop and Three Screw Rugers were modernized compared to the Colt Single Action Army, in that they had adustable sights instead of the Colt's fixed sights, and they used wire coil springs instead of the Colt's flat leaf springs. Bill Ruger chose coil springs due to their greater durability, claiming that it solved one of the primary weaknesses of the Colt design.
The early models of the Blackhawk still operated the same way as the Colt, in that the hammer was half-cocked to load and unload, and that the firearm was not safe to carry with all six chambers loaded due to the hammer resting upon the sixth chamber. In 1973, in order to eliminate accidents occurring from the hammer jarring against a round loaded in the sixth chamber, Ruger introduced the New Model Blackhawk. The New Model Blackhawk did not require the hammer to be half-cocked for loading and unloading, and employed a transfer bar mechanism which prevented the cartridge under the hammer from being fired without the trigger being pulled. The New Blackhawk was seen as limiting firearms accidents and legal liability. Ruger then began offering a retrofit program, offering free transfer bar conversions to earlier variants of the Blackhawk.
Over the years the Blackhawk has appeared in a wide variety of models. These models include:
New Model Blackhawk: Produced in blued steel in .30 Carbine, .357 Magnum, .41 Remington Magnum, .44 special and .45 Colt; produced in stainless in .327 Federal Magnum with an 8-round cylinder, .357 Magnum, and .45 Colt. Multiple barrel lengths were offered in many of these configurations.
New Model Blackhawk Convertible: The cylinder of a Blackhawk is easily removed, and can be replaced with a cylinder for a different cartridge of the same diameter. Ruger has offered "convertible" cylinder revolvers in .45 ACP/.45 Colt, .38-40/.40 S&W/10mm Auto, and .357 Magnum/9x19mm Parabellum. Other than being sold with multiple cylinders, these firearms are identical to the Blackhawk.
New Model Super Blackhawk: Produced in blued and stainless, with or without a rib for mounting a scope. The Super Blackhawk is built on the same frame, but with a larger grip (in the 7.5" and 10.5" barrels) and unfluted cylinder (except for the 5.5" barrel), in order to more effectively deal with the recoil of the .44 Magnum. As well, ejector rod housings and grip frames are of steel, versus aluminum for those same components in the Blackhawk.
Vaquero and New Vaquero: With the popularity of Cowboy Action Shooting came demand for a single action revolver that was more traditional in appearance. As the standard Ruger Blackhawk departs from the Single Action Army looks due to its adjustable sights, Ruger offered a fixed-sight equivalent to cater to buyers wanting a more traditional appearance. In all other ways the Vaquero was identical to the Blackhawk, though offered in slightly fewer variants.
Bisley: The Bisley grip is a type of angled grip developed by Colt for target shooting at the end of the 19th Century. Ruger's "Bisley" offerings incorporated a Bisley-style grip.
Old Army: The Old Army is a percussion ("cap and ball") black powder revolver based on the Blackhawk frame.
