If it's for outdoors (hiking etc), I'd recommend the Glock 20... it's one of the only (if not THE ONLY) 10mm left that you can buy new. I don't like the G-29 as much because of the number of rounds you lose.
A revolver might be best, but I like lots of rounds in my guns... so that discounts a revolver (in my book). That's simply a personal preference.
