The Model 648-2 is a stainless-steel K-frame revolver chambered in .22 WMR with an 8-round fluted cylinder. Its DA/SA action is paired with the modern S&W cylinder-release thumbpiece for familiar, straightforward operation.
The 6-inch barrel is a heavy, full-underlug design with a serrated rib and a knurled ejector-rod tip, with the underlug shrouding the rod via a longitudinal relief slot (the rod and knurled tip remain visible). The tensioned two-piece barrel assembly is a defining feature of this variant.
Sight regulation is handled by a micrometer-click adjustable rear sight matched to a pinned black blade set in a ramped front base. This adjustable sighting setup supports precise zeroing for .22 WMR loads.
Construction is all stainless steel with a satin stainless finish across the frame, cylinder, receiver, and barrel. Black synthetic finger-groove grips provide a secure, hand-filling hold. An internal key lock is present.
Markings include the yoke cut stamped "648-2" and "MADE IN U.S.A. MARCAS REGISTRADAS SMITH & WESSON SPRINGFIELD, MASS." The crane carries assembly number "576." Manufacturer part number is 12460, and the revolver is made in the USA.
