If I knew I was going to be encountering a 250# hog rider jacked on meth, my 9mm wouldn't be my first choice in firearms. If I knew a 250 hog would stand on his hind legs and let me shoot at his sternum and not his shoulder, I might be more inclined to use my 9mm.
Seriously, when I hunt anything my objective is to put an animal down for the count as quickly as possible, not punch a hole or two and track it all over the county.
