Unfired condition means unfired after it has left the factory.
I agree with that statement but, I have seen guns that for all visible signs were an unfired gun, chamber and barrel and no cylinder ring.
But the gun had been beat round so much and had so many scratches I didn’t agree that it was the same as an unfired gun and did not buy it.
The only gun that would mean anything to me as an unfired gun would be a collector piece. But I don’t and won’t own any collector guns so condition is more important than fired or not.
