What's Included
- Ruger Security-Six 1976 Bicentennial .357 Magnum revolver
The 1976 Bicentennial rollmark is a defining feature of this revolver, identifying it as a commemorative-year production with "MADE IN THE 200th YEAR OF AMERICAN LIBERTY" neatly applied to the right frame. It carries a Southport, Conn. U.S.A. barrel address and the adjustable-sight, square-butt configuration associated with this Security-Six variant.
Construction is all stainless steel with a brushed finish across the frame, cylinder, and barrel. Ruger's investment-cast frame delivers notable durability, while the fluted six-shot cylinder and ejector-rod shroud with a partial underlug keep the profile balanced and purpose-built.
The sighting system is straightforward and effective: a ramped, serrated, pinned front blade paired with a fully adjustable square-notch rear. The wide, checkered hammer spur and smooth-face trigger complement the double-action/single-action mechanism.
Ruger's transfer-bar safety is integral to this model, and the revolver retains the classic checkered wood grips with Ruger medallions on a square-butt grip frame. Chambered in .357 Magnum with a 4-inch barrel and six-round capacity, it reflects the Security-Six series design ethos of the 1970s.
