What’s Included
- Original box
The Old Model (three-screw) lockwork and fluted six-shot cylinder define this classic single-action Blackhawk. Chambered in .357 Magnum, it provides the traditional Ruger Old Model handling with the robust build that made the series well known.
The sighting setup includes an adjustable rear sight set into the protected topstrap (non-flattop) and a ramped front sight with a serrated face. This configuration supports precise, repeatable sight alignment.
Construction is blued steel for the frame, barrel, cylinder, and receiver, paired with an aluminum-alloy grip frame. Smooth walnut grips with Ruger medallions complete the period-correct look and feel.
This example is cataloged as BKH-36 and was manufactured in 1958 in the United States. Ruger offers a free factory transfer-bar safety retrofit for Old Model single-actions, should the next owner choose to pursue that option.
