The Kirst Konverter allows you to fire cartridges with your Cap & Ball revolver, just like the original conversion revolvers commonly used to settle the western frontier. Howdy, my name is Walt Kirst I invented the Kirst Cartridge Konverter™ back in the 1990’s for folks who were interested in shooting Civil War and Old West replica firearms, and for those who favored a percussion style revolver that could shoot centerfire ammunition.
