Question...When I pick-up the (used) revolver I put money on (Colt MK V .357 Mag. Trooper) and I bring it in for inspection, How does it work with the ballistic info they collect? As I said, "it's a used revolver" I heard when you buy a new handgun the manufacturer supplies that info. In a sealed container. What happens in the case of a used handgun? Is it the responsibility of the dealer, is it my responsibility or do they fire the handgun when I bring it in? Any info would be useful.
