As the 20th century was about to debut, the brass at Smith & Wesson decided on a new double-action revolver design called the Hand Ejector Model. More powerful cartridges were in high demand so the company developed a solid frame with a swing-out cylinder to replace its top-break double actions.

In the years immediately following World War II, experimenters had been developing ever more powerful loads for the .44 Spl. cartridge. It was natural that a more powerful counterpart to that round should be developed in the same way that the .357 Mag. evolved from the .38 Spl.
