Ruger New Model Blackhawk Flattop Convertible .45 Colt/.45 ACP, 5.50 inch Stainless Single-Action Revolver (2012)
This Flat Top Convertible Blackhawk delivers dual-caliber versatility in a stainless, full-size single-action revolver. Built in 2012 and made in the United States, it features a 5.50 inch barrel, adjustable iron sights, and the classic flattop topstrap profile.

This New Model Blackhawk Flattop Convertible is a dual-cylinder .45 Colt/.45 ACP revolver designed for flexibility. The .45 ACP cylinder headspaces on the case mouth, so no moon clips are required. The transfer-bar system allows safe carry with all six chambers.
Construction is all stainless, including the frame, barrel, cylinder, and receiver, with a brushed/satin stainless finish for a clean, durable appearance. The six-shot fluted cylinder and single-action-only mechanism deliver the classic Blackhawk experience with modern safety updates.
Sights are fully adjustable iron sights, pairing a serrated ramped front with a fully adjustable rear to fine-tune point of impact. The 5.50 inch barrel length strikes a practical balance for sight radius and handling.
Ergonomics and appearance are enhanced by smooth ivory-color grip panels with Ruger medallions. This U.S.-made example is cataloged as KNVB-455X with Ruger model number 05241, aligning with its 2012 manufacture and flattop topstrap profile.
