The Smith & Wesson Model 647 is a double action/single action revolver chambered in .17 Hornady Magnum (.17 HMR), built on the medium K frame. The K frame has served as the foundation for Smith & Wesson's mid size revolvers since the early twentieth century, offering a balance of strength and moderate size. The 647 uses a stainless steel construction throughout, 6-round cylinder, and incorporates an internal firing pin.

This example features an 8 3/8 inch full underlug barrel with a brushed stainless steel finish. Sights consist of a blade front and a micrometer click adjustable rear. The revolver is fitted with Hogue rubber monogrips bearing S&W logos. No original box or accessories included.
