I have never figured out why a buyer wouldn't put their social security number on the 4473 form. Every employer I've ever had has my ssn, every bank I deal with has my ssn, the medical people I deal with have my ssn, probably a couple places I don't know about have my ssn, why wouldn't I give it to a federal agency which is where I got it from? You will probably get your firearm after 3 days but know that if a dealer does not get a call back it is their choice to proceed with the sale. Most of the buys I have made lately from an ffl they made the call before taking the money. Saves messing up their till if there is a problem I guess.
