If I were going to have a declared firearm in luggage I would disassemble it, put the slide and barrel in one bag, the frame in another. After the declaration someone said to then pull out a roll of heavy duct tape and wrap the luggage a couple of times.

I used tape for a while, then I transitioned to a locking strap with a combo lock.

It both made the bag more noticeable and added another barrier to entry.
