Regarding Private Party transfers, at Firing Line we do not take possession of the gun until the "buyer" passes the background check. Then both parties come back in, we put the gun in the books, give it a log number, then one of the 2 parties pays the transfer fee, the buyer re-certifies the 4473 and you're out. If there are hi-caps involved in the transfer we tell the 2 parties it is not legal for us to sell or transfer those hi-caps, and to do what they feel with those mags, out from under our roof.
