Built in stainless steel using Ruger's investment-cast construction, this Security-Six combines strength with a brushed stainless finish. The solid one-piece frame lacks a sideplate, a hallmark of the series, and the transfer-bar system provides safe carry with all six chambers loaded.
The 6-inch stainless barrel includes an ejector-rod shroud, a ramped front blade, and a fully adjustable rear sight with windage and elevation screws. This adjustable-sight configuration distinguishes it from the Police Service-Six and Speed-Six models.
Chambered in .357 Magnum, the six-shot fluted cylinder and DA/SA action offer versatility for a wide range of shooting applications. The brushed stainless finish is carried across the frame, cylinder, and receiver for a consistent look.
Ergonomics are enhanced by square-butt, checkered walnut grips with Ruger medallions. The revolver was made in the United States and reflects the Security-Six series features popular in the 1970s era.
Markings include ".357 MAGNUM CAL." on the barrel with the Southport, Conn., U.S.A. address. A documented note indicates a discrepancy between the butt stamping and the provided serial; the listing follows the provided serial per evidence authority.
