Shoot or no
I've watched the dialog go on about shoot or don't shoot and it isn't that simple.
I live in Florida where heat and humidity play hell on tools, people and especially hand held things that are very complex, like revolvers.
Then there's the risk of damaging pristine grips that cannot be replaced. OK, get a shooter grip and remove them. Soon it begins to be more nerves about maintaining condition and fiddling about with a very rare piece, then it does the joy of shooting it.
If you simply must, take it out once and have fun, then clean it, polish it and admire it. Love shooting it? Get yourself a shooter grade, there are lots of K frames and lots with a much better sight picture than these early M&P's.
I won't shoot this one from 1919-1920...would you? It has a turn line, but that's about all.
