You are the only person that is supposed to have access to the gun case so I wouldn't recommend TSA locks of any quality or type except on the ammo box.I have the pelican suitcases and they are great but heavy. You’ll have to limit your packing a bit. I am using the heavy duty TSA locks now on my gun case. If they want in they’ll get in but at least they don’t have an excuse to leave my gun. Always a debate.
