Keep in mind you're shooting a gun built using different metals from today, that is usually in the 120+yr old range, so what you expect from it should be different. A completely rebuilt and overhauled gun like a reichsrevolver or Chamelot Delvigne, if shot with light loads, will be your best bet. The Chamelot Delvigne's/MAS revolvers are very solid, but if things do wear or break on them, they're very difficult to make parts for. The Reichsrevolvers are much simpler, so possibly a better route for someone wanting to put a lot of rounds through one. In all cases, the metal quality is lower, or simply different than today, and the expectations of what is reasonable are different as well. If you're skilled at making parts and keep a good eye on the gun for any developing issues and fix them before they damage the gun you should be ok.
