I have a shotgun that was purchased by my father many years ago then later when I got older, he gave it to me while both being Louisiana residents. Legally, the gun is mine but with no paper work. Now, I have since moved to Texas, the gun is still mine. Is it legal?
Hypethetically, even if he just now had given it to me, while he is a Louisiana resident and me a Texas resident, who else would know (Feds/LE) that he did not give it to me before I moved to Texas? It was purchased before my birth and we lived in the same state for about 36 years. Easily defensible that he gave it to me while being residents of the same state. Technically, still against the law I suppose, but how could that be enforced, unless my own father rats me out?
Now, buying a new gun today, different story, unless FFL transfer.
