For all those fixed on the MAY part of the law, here is another MAY to consider, Letter "A". Scroll down to Letter "E". nowhere does it say MUST, or SHALL deliver the firearm. It says after the transaction. SO I guess the FFL does not have to EVER send in the paperwork or release the firearm after "NOT DISAPPROVED"
Very interesting indeed. Where are the legal eagles on this part.
