What’s Included
- Ruger Security-Six .357 Magnum stainless revolver (4 in. barrel)
Built with stainless steel throughout the frame, cylinder, and 4-inch barrel, this full-size Security-Six wears a satin stainless finish for a clean, classic look. The sideplate-less, investment-cast construction contributes to the model’s solid feel and straightforward serviceability.
The revolver operates in double-action/single-action and uses Ruger’s transfer-bar system, enabling safe carry with all chambers loaded. It has an exposed, knurled hammer spur and a push-button cylinder release. The six-shot fluted cylinder and short underlug/ejector-rod shroud reflect the classic Security-Six pattern.
Sighting is handled by adjustable iron sights: a pinned, serrated ramp front and a fully adjustable rear. The checkered walnut grips with Ruger medallions pair with the square-butt, high-back 151-prefix frame for a confident, traditional grip profile.
Markings include the Ruger Southport, Conn. U.S.A. barrel address and the .357 Magnum rollmark. This example aligns with production from the 1970s–1980s and was manufactured in the United States.
