I would bet if you are charged by a big hog, you wont get a shot off any way so it doesnt matter what you carry.
I hunt hogs 3x a week with dogs and a knife, i been charged more times than i care to think about. I usually have a 22 mag single action pistol when we go but not for charging hogs. only used it once when the dogs bayed in a log jam and it was too dangerous for the catch dogs to go in. it drops em like a hammer. I would say use what you have, my every day carry is a glock 23 and I have dispatched hundreds of hogs in traps with it.
