Are there any special regulations I need to be aware of when it comes to flying with my firearms? Specifically flying out of Illinois to Arizona? Assuming stops in KS, TX, NM and AZ in case that's relevant. I'd like to avoid doing anything that could land me in trouble. Specifically, any relevant FARs or federal regulations someone can direct me about: (1) Whether it's legal to carry my guns (pistols) on my own private plane; (2) The requirements for storing them aboard; (3) Any restrictions on states that wouldn't permit you to have them? I live in IL which has the most onerous gun laws of any state I can think of, so I'd think I'm OK to have them in other states but certainly not positive on that. And any special considerations aside about flying with them? It'd be just the guns themselves, no boxes of ammo. Going to buy that at my destination before we go shooting.
