If you go to a black powder club if you can, and talk to the members. The black powder guys don't buy all the fancy items from a catalogue they would rather make them. I have gone to black powder shoots and rendezvous for years and bought most of my items off the trade blankets. Ever got some of my guns off them, including pistols. Places like Dixie Gun Works and Track of the Wolf have great items. If you can’t purchase something you can at least get an idea what’s out there. I have quite a few spare items that I would part with that I never use. If you want to send me a want list I will check on what I have and get pictures back to you. Some are new.
If you buy a pistol be sure to use No10 caps on the cylinders not No11. The No11 caps have too much space between the cap and nipple and cause the chain fire. I see guys putting shortning around the top of the bullet to prevent chain fire. If you think about it where will the chain fire occur not on the sealed end of the cylinder but the cap end.
