Here are a couple of (pretty poor) photos of the 67. Despite the lack of focus in the second one, you can still see how the top outer corner of one rear sight blade is crushed. That's the only significant cosmetic defect on this gun. Functionally it seems to be very good.
I suppose I always have the option of replacing the rear sight, but first I want to take the gun to the range to see if it's an issue at all.
