Keith encouraged Smith & Wesson and Remington to produce a commercial version of this new high-pressure loading, and revolvers chambered for it. Smith & Wesson's first .44 Magnum revolver, the precursor to the Model 29, was built on December 15, 1955, and the gun was announced to the public on January 19, 1956 for a price of US$140 ($1330 in 2020 dollars) Julian Hatcher (technical editor of "American Rifleman") and Keith received two of the first production models. Hatcher's review of the new Smith & Wesson revolver and the .44 Magnum cartridge appeared in the March 1956 issue of the magazine. Smith & Wesson produced 3,100 of these revolvers in 1956.
