and the .44 Magnum cartridge appeared in the March 1956 issue of the magazine. Smith & Wesson produced 3,100 of these revolvers in 1956. By the summer of 1956, Sturm, Ruger became aware of this project and began work on a single action Blackhawk revolver for the new .44 Magnum cartridge. There is a popular rumor that a Ruger employee found a cartridge case marked ".44 Remington Magnum" and took it to Bill Ruger, while another says a Remington employee provided Ruger with early samples of the ammunition. Ruger began shipping their new revolver in late November 1956. The .44 Magnum case is slightly longer than the .44 Special case. This alteration was not primarily intended to increase the propellant capacity of the cartridge, but rather to prevent the far higher pressure round from being chambered in older, weaker .44 Special firearms and potentially causing injury or death to shooters. The .44 Magnum was an immediate commercial success. The direct descendants of the S&W Model 29 and the .44 Magnum Ruger Blackhawks are still in production, and have been joined by numerous other makes and models of .44 Magnum revolvers and even a handful of semi-automatic models, the first being produced in the 1960s. The film Dirty Harry, prominently featuring the S&W M29 shooting .44 Special ammo, contributed to that model's popularity. Ruger introduced its first long gun, a semi-automatic carbine called the Ruger Model 44 chambered for .44 Magnum, in 1959. Marlin followed soon after with the lever action Model 1894 in .44 Magnum. Having a carbine and a handgun chambered in the same caliber is an old tradition; the .44-40 Winchester was introduced by Winchester in a lever action in 1873, and Colt followed in 1878 with a revolver in the same caliber. The .38-40 Winchester and .32-20 Winchester were also available in both carbines and revolvers, allowing the shooter to use one type of ammunition for both firearms. Although improved modern alloys and manufacturing techniques have allowed even stronger cylinders to be made, leading to larger and more powerful cartridges such as the .454 Casull and .480 Ruger in revolvers the same size as a .44 Magnum, the .44 Magnum is still considered an exceptional weapon. In 2006, to commemorate the 50th anniversary of the .44 Magnum, Ruger introduced a special 50th anniversary Blackhawk revolver, in the "Flattop" style.
