There is an AG opinion letter floating around that loaning a firearm between family is not a change of possession and is permissible. Since that is the case, it not an issue for a father, to loan his son a firearm the father owned prior to Oct 1, 2013.
Has anyone seen this opinion?
Yes, anyone know where a copy of this letter can be found?
Oh Yellowsled, nothing is a "simple question" anymore .
Sorry guys, not an AG opinion on the definition of transfer and possession, it is actually a court case from 2006 (Chow v State)

While it related to regulated handgun loan at the time, one could surmise that it would apply to a formerly regulated long gun today.
