Of course it has been fired! What kind of weirdo would buy a new gun and not shoot it at least once? The unfired statment is stupid. No one can prove it and it doesn't matter anyway. The real question is about whether the gun is worn or not. The unfired statements were lies to cover the ultimate "not worn" condition which you just violated by opening the breech to look at the face for rings around the firing pins. Your hand on the stock just removed a couple of molecules of stock finish and blue; moving the top lever ground off a couple molecules of steel from the mating surfaces. If it stood around in a case for a century there is wear from case contact. Why would firing be bad if the gun were not worn?
