The stainless-steel construction includes a solid one-piece investment-cast frame with no sideplate, giving the Security-Six its robust foundation. The brushed stainless finish is consistent across the frame, cylinder, and receiver, and the six-shot cylinder features six flutes.
The 2.75-inch stainless barrel is cut with a full-length rib and paired with a ramped blade front sight and fully adjustable rear sight. Factory markings include the Southport, Conn., U.S.A. barrel address and standard Ruger warning rollmarks. This short adjustable-sight setup is documented within Security-Six catalog options.
Operation is double-action/single-action with a smooth trigger, a spurred and checkered hammer, and Ruger’s transfer bar safety system. The combination offers straightforward control with proven internal safety.
Aftermarket smooth ivory-colored synthetic grip panels complete the revolver’s presentation. The 156 serial prefix corresponds to estimated circa 1980 production in the United States.
