I bought one a few years ago, didn't like the DA/SA, and sold it to a guy who wanted it more than I did.
Beautiful gun, in factory nickel, and seemingly unfired.
I paid $600, which seems to be absolutely top dollar, but cheap for a rare piece.
That looks like a nice clean example, congrats on the fine addition, reminds me of the one I had in nickel. I have a S&W 639 with a set of stag grips, it is an old police gun that gets the easy life now. Hope it beings you years of happiness at the range.
