I found a Uberti cattlemans B.P. in a shop used, I am interested in the availability of a conversion cylinder for this B.P. Peace maker looking clone, does anyone know where I might find one? Thank you Max.
The cap and ball version of the Cattleman has an offset firing pin and matching frame hole to prevent conversion to cartridge cylinders. There are no commercially available conversion cylinders for that model.
The gun was intended for sale in countries where ownership of cartridge firing handguns was prohibited (such as the UK).
Some years ago, I installed a centerfire firing pin on mine, egged out the hole in the recoil shield to the side a bit, and installed a .45 Colt cylinder. I put two rounds in the cylinder, stepped outside, and pulled the trigger. The first shot went BOOM just fine, but nothing happened when I pulled the trigger a second time. I thumbed the hammer back to half cock, opened the gate to unload it, and there was already a case under the gate...? With no primer in it...? BOTH cartridges were fired, and BOTH were missing their primers...? The hole in the recoil shield was now large enough for a primer to be swaged back through the hole under pressure, escaping gas recocked the hammer, turning the cylinder, and the hammer dropped on the second case. I had created a full auto revolver! I replaced the BP cylinder, re-installed the off center firing pin, and went back to BP & round balls.
This would be an easy conversion with a firing pin bushing or welding up the hole and machining a new one, but don't try it my way!
The BP Cattleman was designed specifically to fire only as a cap and ball percussion revolver. The cost of modifying a Percussion SAA to shoot cartridges would be costly & would ruin the pistol for C&B shooting. If you want a cartridge gun, I'd go buy one of those.
