If you are loking for authentic antiques, I can't help you. If you are interested in reproductions, Bass Pro at Arundel Mills (Hanover, MD) stocks a good number of Pietta reproduction pistols (under the Traditions label) and does carry powders, caps, cleaning supplies, etc. The best bet I have found for reproduction arms is online at Cabelas.com. Good luck! If you do find the right place, I would love to know it whereabouts, too.
