Why don't you just "sell" him one for a token price of $10 or so, and have him write you a check? He can put "Springfield Armory 1911". or "Glock 17" in the memo line. This way, God forbid, if anything unforseen were to unexplicably happen and the cops show up at your door wondering why your gun was traced to 15 corpses found in a Camden, New Jersey parking lot, you can honestly tell them, "Sorry. Not mine. Here's the check I got when I sold it.".
