Why not just bring it with you?
If you're driving, change how it as transported as needed.
If you're flying, lock it in a hard-box, take the bag to the check in desk for your airline, and say "Hi, I'd like to check a firearm, please." They'll walk you right through it.
It's how I brought my XD back from my parents' house in 2006.
You can even check ammunition this way.
It's how I brought several hundred .45 rounds from my parents'
house in 2007.
