I have two travel cases from Impact Case, a single and a double version. Both of these cases have carried my firearms all over the world, with no damage whatsoever to my guns. The double case has wheels, and both cases use either a single or two rods to go thru the holes in the latches to securely lock the case. Good, high quality cases, if you prefer aluminum over polymer.

I'd rather be a free man in my grave, than living as a puppet or a slave....
