Sorry, TDL, no, not right at the moment.
We don't have any case law to interpret 594 yet. Previous laws were either clear, or easily understood to mean that they applied to a change of ownership (possession), however, 594 is neither. There is precedent in law that a change of ownership is not required, merely a change in who is holding the gun.
Take your gun to a gunsmith, to get something fixed. If it takes overnight, or longer, the smith (FFL) has to log it in his records, AND when its fixed and he returns it to you , he has to run a background check on YOU, the legal owner, in order to return your property to you.
This is current law. Under 594, without any defining guidance (currently pending, we are told) ANY transfer of possession could be a crime, unless done through an FFL. BECAUSE 594 makes certain specific exceptions, that implies that all other instances are covered by the law. SO, me handing you my latest 1911A1 in my living room is a crime, and you handing it back is another crime, IF the law is going to be interpreted that way.
At this point, we don't know what the enforcement is going to be, or what degree of infraction is going to be an enforceable crime.
