Me personally I would go with a 9mm (some pistols hold almost 20 rounds per mag) a 12 gauge with a folding stock and short barrel (police style not sawed off), and a M14 EBR. 9 holds a fair amount of ammo and aint to bad in general, 12 gauge for CQB and hunting ammo's everywhere, and M14 because it has range and stopping power you might need for people or game, ammo can be a little heavy but I think it worth it. If not you could always go with a AR 5.56 has good range stopping power aint great but it lighter the 308
