Ok, it' s like a really long sharp stick.

All I' m stating is what I' ve seen in my personal experience. My buddy (a non-hunter) and I were driving along one day last year and he hit a deer. Just a little doe. It only broke both of it' s back legs so it was still alive but couldn' t get up. So he told me to finish it off and handed me his 9mm pistol he kept under his seat for self protection. I got out and shot the doe in the brain. It didn' t even phase it. All it did was make the thing kick around harder. So I shot it again. And again behind the shoulder. It just kept living. After the one behind the shoulder it slowed it down but it was still very much alive. I had to slit it' s throught to end it. I never asked what kind of ammo he had in that thing. Even with FMJ ammo the first shot in the brain should have ended that.

That is why I will never see a 9mm as much better than a sharp stick. I' d rather have one than nothing, but if I had any kind of a choice I' d pick something with more knockdown power.
