Thanks for the replies. I'll head over to a local gun shop here to see about a case. I just need something for the trip, so the cheaper the better.

As for a "TSA lock," what's special about those vs a padlock or combo lock?

Appreciate the anecdote, but I need to do this in a way that won't get me fined, detained, or arrested. Labor Day travel is going to be bad enough without me adding to it.
