Forget what I said earlier about low-balling this gun. When you find a nice 3rd Gen S&W just jump on it.
I recently bought a LN 2nd Gen S&W 659 for $300.00. My gunsmith just got done detail stripping it & said that this almost 30 year old gun gun had no evidence of wear, he charged me $40.00 for an inspection and a little reliability tuning. So I'm all in with this gun for $340.00, and it is just the nicest gun to shoot, and it's built like the door on a bank vault!
