I buy Pietta parts sets from Cabela's for 25.00 http://www.cabelas.com/cabelas/en/te...817&hasJS=true They sell them for Remingtons and Colts they also sell cylinders for 39.00 http://www.cabelas.com/cabelas/en/te...817&hasJS=true I pre fit the parts kits in my guns using the existing parts as a guide and keep them in my range box. If i have a break down i just swap out the bad part and i am shooting again.
