I keep hearing advise for people to get a "TSA" lock for their outer luggage lock. If you value your firearm and want to see it at the end of your flight, please don't do this. Too many people other than TSA have the key for these locks and your chances of having your firearm stolen increase significantly using these locks, in my opinion.

Lock both your gun case and outer luggage lock with your own personal locks. If TSA needs to get into your bag, they will notify you to come open it for them. Having a TSA lock is inviting someone to steal your firearm, because, why else would one use a TSA lock other than to "secure" a firearm.
