Didn't answer the poll, nothing seemed to fit quite right.
But I've replaced parts in many of my revovlers, Colts, Smiths, and Rugers. Parts swapping is part of the fun of single actions.
Never replaced a barrel, but have realigned them after they rotated in the frame.
I started disassembling revovlers when they were cheap and just kept it up, but only when necessary, not for routine cleaning.
