Interesting reading. Man, I feel for you. I used to do living history reenacting and have had quite a few Pedersoli and Miroku repros. *sigh*
If I were you - but of course I'm not - I'd get a Ruger Old Army. I've got two, and they are somewhere between a good old Mack truck and a Swiss watch. Strong as heck and run like clocks.
Good luck - revolvers really are a good way to burn black powder, so I hope you have a happy ending!
