The only other thing that comes to mind is the ammunition. If you were to fly somewhere (which your not), the airlines generally allow you to bring ammo along. They stipulate full boxes, ie- 50 rnds in a 50 rnd box, and locked up in a piece of luggage other than, and separate from the firearm itself. So a separate lockable case for the ammo might be worth considering. I don't know what more you can do than that.
