Smith & Wesson Schofield - With variations including the "Russian Model", so named because it was supplied to the military of the Russian Empire. The S&W Model 3 was originally chambered for the .44 S&W American and .44 Russian cartridges. Model 3 revolvers were later produced in an assortment of calibers, including .44 Henry Rimfire, .44-40, .32-44, .38-44, and .45 Schofield. Heavily used in the early west.
Smith & Wesson Second Model Schofield Single Action Revolver - The Schofield was designed and built to compete with the Colt Single Action Army. It was originally chambered in .44 S&W American, and then in .45 Schofield. Its break action design allowed for fast reloads, but incompatability with the .45 Long Colt catridge limited its popularity.
