First, thank you John Rippert for bringing the 640's to my attention.
Secondly, thank you to Centerfire systems for the way they do business. I ordered the gun on a Thursday night after receiving their "in stock" e mail, gun was shipped Friday. Lgs received it Monday, picked the gun up yesterday.
Overall, I would rate the revolver as very good condition. Better than most I am seeing photos of, on par with what Erich posted. No paint on the sight ramp, no gunk in the internals, serviceable rubber stocks.
IMO an excellent value. Hope the rest of you guy's are as happy with your's.
