No. It makes no difference if the weapon is unloaded or not.
to my understanding there is no legal definition on the books for an "unloaded firearm". however as Oregon is one of the more lenient states when it comes to firearm laws and open carry is legal in most areas of the state and there is no loaded or unloaded requirement for open carry. I hope this answers your question but if not with a little more info i am sure i could help you ...
Yes. It has to be unloaded and secured, you have to declare it, and the firearm itself has to be legal both at the point of origin and at the destination.
"Unloaded" as in it does not have any ammunition. It is unloaded.
It is legal to carry a firearm into a bank in Wyoming as long as the person is a peace officer or possesses a valid permit to carry a concealed firearm.
It depends on the locality. In some U.S. states, it's perfectly legal to carry a loaded handgun where you can access it in a vehicle, but in some it isn't. You can, generally speaking, transport and unloaded and inaccessible firearm in a vehicle. Check your local laws.
NO
13 or 18? depends on state laws.
Not a good idea. First, you have to ensure the firearm is legal in California - major difference in state firearms laws between AZ and CA. Second, you need to keep it locked away and unloaded in California, as they do not reciprocate concealed carry permits.
Verify it is unloaded
Any time that immediate use of the firearm is not anticipated.
