The Security-Six is a double-action/single-action revolver chambered in .357 Magnum with a six-shot fluted cylinder. Ruger's transfer-bar safety allows safe carry of all six chambers, a system trusted in widespread U.S. law enforcement service.
This example has a 6-inch barrel with a short underlug and an ejector-rod shroud, paired with a knurled ejector-rod tip for positive extraction. Sights include a plain ramped front and an adjustable rear, providing a clear sight picture.
Construction is all steel with a blued finish: alloy-steel frame and receiver, and a blued steel cylinder. The design uses a solid frame without a sideplate and a square-butt grip frame. It wears two-piece checkered hardwood grip panels and an exposed hammer with a checkered spur.
Notable production details include its early 150-prefix block and 1970s era manufacture in the United States. The cylinder features offset stop notches to enhance strength while retaining the classic fluted profile.
