I have taken apart my C & B revolvers . . . as far as my more "modern" ones . . no. My attitude is "if it ain't broke, don't fix it". My attitude on those is that if I have a problem, I know several gunsmiths I can take it to . . . they have far greater knowledge than I and I'm sure more access to needed parts if necessary.
Now if you were talking semis . . .yes I have. I still haven't taken my new Ruger MK III Target apart yet though . . . and I'm really not looking forward to it.
If a pair of '51 Navies were good enough for Billy Hickok, then a single Navy on my right hip is good enough for me . . . besides . . . I'm probably only half as good as he was anyways. Hiram's Rangers Badge #63
