Ruger Old Model Blackhawk Convertible .357 Magnum / 9mm, 4 5/8 in Barrel (1972)
This 1972 Ruger Old Model Blackhawk Convertible stands out for its scarce 4 5/8-inch barrel, factory-fitted dual-caliber cylinders, and untouched three-screw lock-work. Fewer than 500 BKH34X revolvers were produced, making this example a desirable find for shooters and collectors who appreciate original Old Model features and smooth balance.

What’s Included
- Factory Ruger 9 mm Luger conversion cylinder (fluted, loose)
Factory-built as a convertible, this Blackhawk comes with correctly-timed .357 Magnum and 9 mm cylinders, allowing straightforward caliber changes without tools.
The 4 5/8-inch barrel variant was produced only from 1967 to 1973; Ruger records indicate fewer than 500 units configured as BKH34X, enhancing this revolver’s scarcity.
Its pre-transfer-bar, three-screw action remains unmodified, retaining the original hammer-mounted firing pin that many enthusiasts seek for its crisp single-action feel.
Constructed on the lighter .357-size frame, the revolver offers quick handling while still benefiting from full-size sight radius and adjustable iron sights for precise shooting.
Transitional silver-eagle walnut grip panels mark late Old Model production and complement the deep blued finish on the alloy-steel frame, barrel, and cylinder.
