As usual, the OP's original query was sent to crazytown, and not by me for once.
Per the original question, no, don't use TSA locks on your gun cases. I highly recommend not using any combo locks of any kind either. They are fairly easy to defeat and they can't take the beating, so sometimes they won't open.
Use a good keyed padlock, not a 3 pin master lock that a paperclip can defeat but something a little more secure. If you're traveling a lot I recommend spending the money and getting a couple American Lock series 200 or 5200 govt locks keyed the same.

The Govt ones retain the key when open so you don't have a choice but to lock it.
You can find them at good prices on ebay as well and a good locksmith can key them the same if they are all the same key format.
