FROM WIKIPEDIA

The Smith & Wesson Model 19 is a revolver produced by Smith & Wesson that was introduced in 1957 on its K-frame. The Model 19 is chambered for .357 Magnum. The K-frame is somewhat smaller and lighter than the original N-frame .357, usually known as the Smith & Wesson Model 27. A stainless steel variant of the Model 19, the Smith & Wesson Model 66, was introduced in 1971.
