Mine came today, picked it up at lunch. Great shape with a bit of character. Much better trigger than my current 640-1, but the ejector rod is a bit sticky so the innards are probably gummy too. I'll pop the side plate after dinner, it's going to get a good cleaning.
Then too decide on grips.
I'm real happy with the score !
No carbon rings, but the yoke screw is pretty buggered up, I think the face got cleaned regularly on a buffer.
Rings on the blast shield.
Ding on the top strap.
