RE: black powder pistol ?
I had 4 replacements sent to me from cabelas. The best way to fix them is to junk them. They are 100% guaranteed POS's!
Find a nice piece of wood, make some hangers and hang that thing on a wall. Its no good unless you want to try to throw that pistol at the target.
After shooting my first one, The barrel used to fly off. second, 3ed 4th wouldnt either cock all the way, wouldnt even come back. They are pure junk.
