I ignore the "looks unfired" and "if fired, orly a little" comments. I prefer ANIB descriptions and expect then to see no visible signs of use; no blue loss, barely discernible turn ring (if any), and no indication on the recoil shield of being fired. And the box, paperwork and tools will be with the gun. I've rarely encountered an "unfired" gun that didn't have those with it.
Some years ago I handled a M27-2 in nickel which at the time was priced at about double the market price. I asked why and the clerk assured me it was "unfired since leaving the factory, look at the burn marks on every other cylinder." I did, and the burn marks were there, along with a lot of tiny scratches on the front of the cylinder where carbon had been removed and the gun fired again on every other cylinder. Buyer beware, best just to assume it is a used gun and ignore any claims of being "unfired."
