The Smith & Wesson 648 in .22 WMR (brand part no. 12460) is a K-frame double-action/single-action revolver built with an 8-round cylinder, well above a typical rimfire revolver, and a 6-inch full-underlug barrel. Smith & Wesson finishes the frame and cylinder in stainless steel, pairs it with finger-groove synthetic grips, and fits it with a Patridge front sight and adjustable rear sight. Among rimfire revolvers in the revolvers category, the 648 favors target shooters who want high-capacity .22 WMR performance with an adjustable sight system.
