IIRC if you leave your gun with a gunsmith they have to be an FFL. I remember reading that if you left your gun with a gunsmith he has to basically DROS it back to you just as if you were purchasing the gun - 10 day wait and whatnot -but the one time I took a gun in and left it with a gunsmith I had no such hassles.
