Cimarron Richards-Mason 1851 38 Special Revolver 7.50″ Blued CA925

In a historic collaboration, Colt employees Charles B. Richards and William Mason patented their revolutionary idea on July 2, 1872, merging concepts to transform Colt’s percussion revolvers into modern metallic cartridge, breech-loading arms.

Initially, they repurposed existing percussion revolver parts, converting them into efficient firearms. However, as the supply of percussion components dwindled, Colt shifted towards manufacturing entirely new sixguns designed for metal cartridge use. Though production numbers were modest, including around 2,100 1860 Army models and approximately 3,800 1851 Navy models, their impact was significant. Notably, figures like El Paso’s city marshal Dallas Stoudenmire and the legendary John H. “Doc” Holliday famously wielded these innovative firearmsa cut-down Richards-Mason Army Colt and a ’51 new-made Navy model respectively.

Today, enthusiasts admire the blend of classic aesthetics and modern convenience offered by these conversion revolvers, combining the elegant lines of percussion firearms with the practicality of self-contained cartridge sixguns. Recognizing the rarity and expense of original pieces, Cimarron’s Richards-Mason conversions stand as ideal choices for both Cowboy Action competitors and aficionados seeking to experience a piece of firearm history firsthand.
