The mere fact that you asked that question shows you have concerns(and rightly so, especially where hogs are concerned!) with one shot being the stopper, if you would feel more confident with more shots, go with a repeater of some sort. No need to spend your hunts worrying about things, it's a time to be enjoyed. Tight quarters, dangerous game hunting is no place for a single shot gun, period! It is nothing more than flirting with disaster.
