If you are planning on traveling to some distant locale for the purposes of gaining some experience in a different country, you are going to have to part ways with your gun. This is an inevitable consequence of air travel, and it is done for your protection as much as it is done for the protection of the various other people that you are going to be traveling with all in all.
However, while it is understandable that you wouldn’t be allowed to take your gun with you while you are going to a different country, you should also think about the fact that your gun is simply going to be lying there at home where anyone might end up hurting themselves if you don’t prevent this sort of thing from happening.
You can’t just leave your gun lying around unattended since it is a weapon that could be used to wreak all kinds of havoc and destruction if it falls into the wrong hands, and with the large number of people that might want to use your gun for such purposes it is up to you to make sure that no one is able to do so while you are away and can no longer keep an eye on your gun for a reasonably short period of time.
If you check here, you would find out that gun safes are a great option when it comes to this sort of thing. You can find a lot of solutions that would help you hide your gun but it is highly unlikely that any of them are going to work as well as a safe that you can place your gun inside of when you are away.
