There are peculiar collectors who really prize unused objects, whether cars or guns or whatever. I don't understand them. Why have something you can never use? It's like the family up the street who has a Living Room so special that it has never been used in the living memory of any of the kids who live in the house. Their mom cleans it, but she doesn't even sit there when she wants to read quietly... it's too special for even her to use... and it is too special even for beloved grandparents. Freakish.
I, personally, would never buy such an unfired gun. Leave it for the collectors who will hide it away in their safe for another 60 years. I buy guns that are used, and I use them. They are cheaper, and there is no heartbreak when they get holster wear on their bluing.
