I am suffering from an intense desire to convert my old Pieta 1860 army to cartridge. Kirst is offering a gated kit for $325.00 and, verily, I am stricken. My heartsick desire to upgrade my loyal C&B with cartridge "augmentation" is bothered by a nagging skepticism in my mother's voice. The desire to push forward seems righteous but I fear that I might just be an old man making wedding plans with a hooker. If anyone here has tried these new converter kits please share.
