I don't think that is the case if you buy a Gun today and next week youI think that it depends on whether the gun is used or not. There is some law about having a new gun for a year before they can sell new without paperwork. I don't have enough info. to elaborate any farther and may not have all of my facts straight.
I'll bump this up because I'm curious myself.
don't like it anymore you can sell it FTF if you so please !
