I picked up the S&W 67 today. Haven't had a chance yet to give it a good going over, but at first glance it appears to be in the advertised "very good plus" condition. The cylinder is nice and tight. Trigger feels good. PLus it has Hogue Monogrips, which I had not expected.
The only real negative is that it appears the gun was dropped on the rear sight, and the top corner of one of the sight blades is crushed down somewhat. It doesn't appear to have affected the alignment (and in any case the rear sight is adjustable), so it's no biggie.
Overall (not yet having shot it), I'm very pleased so far.
