The gun needs to be shipped in a sturdy box, that's all. It does not have to be in a locked container unless that's what you want to do. When I ship, I wrap it up in corrugated paper (like what is in the middle of a box then put it in an appropriate sized box. Tape it up, address it and send it on it's way. You just want to make sure that it won't shift around and get damaged. For handguns I wrap it up, first a cloth then bubble wrap and it goes into the shipping container. I put balled up newspaper to fill the voids in the box so it doesn't move around.
