Any caliber handgun that begins with .357, or begins with a "4" is suitable. In essence your inquiring about a "back up" on a hunting trip. The factors, will be size, weight, comfort, ease of access, reliability and accuracy.
When camping, I like my .45Colt. SA. with Winchester 225gr Silver-tip JHP's. Will work on four and two legged critters. Easy to draw, hike with, and very, very accurate. I usually have my Remington 870 also, but you'll be carrying a bow.
However, I can see the "comfort" and justification of more rounds, if needed, in the XD semi-auto platform. If it feels comfortable for you on a long hunting trip, and you are accurate with it, bring it with two spare mags, and good luck on your trip.
