1) She then was willing to send me a reg card so I could register the gun as new...
That's WTF....
2) I only know what he told me. I'm 80% sure that his gun had some gunpowder in the barrel and maybe on the gun from only the test firing.
3) But, it is possible that the dealer is shady and is either selling used guns, or allowing people to shoot the guns and then he still passes them off as new.
4) So, I suggested that if he had doubts - the first step would be to contact springfield to see if the gun was ever registered to someone else. 2nd - there is another thread from this guy concerning this very same gun he is asking about.
5) If I remember correctly, the guy also stated that the gun did not come with the spent casing in the envelope - this is also suspicious. It makes it appear that this gun is not new.
6) If it appears to not be new, he could report the business to his BBB office for fraudulent sales. Also, the AG's office might be interested in consumer fraud - especially when it comes to firearms (a hot button issue). And finally - if the guy did it 1x, he might do it a lot - hence the call to the ATF. They may not care. But in a possible scenario where a gun dealer could be passing off used guns as new on a routine basis MIGHT interest them - as they like to hassle dealers for far less mistakes.
7) So, besides "WTF"

and me saying something that appears to be the "stupidest thing someone here has heard in a long time," there was a point to what I was saying.
8)
Obviously, U take 1 thing a step at a time.
If I suspected that I had really bought a used gun that was passed off to me as
new,
and the dealer could not explain the discrepancies, then these would be the steps I would take to fire up a world of headaches for the dealer who wasn't dealing straight.
