That one is in excellent ++ condition. You might even say LNIB (Like New In Box). I can barely see a turn line on the cylinder. I will be a little contrary here and say that shooting it will lower its value, at least slightly, no matter how careful you are.

If you take it to the range on nice days and carefully clean it afterwards, the value won't go down much. But then, they were made to shoot, so it's your choice. I would definitely not carry it afield in a holster, etc. There are plenty of good shooters out there with "honest wear" for that kind of service.
