This is the third in a multi-part series about guns choices, ammo choices, and self-defense. I'd like to the first two---but unfortunately, their website got hacked a little while ago, and they are slowly getting all their old posts back online.
Slowly.
If I can find the older posts, I'll link them as a reply. For now, though, he's got some good (and important, IMO) things to say about self-defense firearm choices.

"
An instructor I trained with summed up the problem of stopping a human being nicely with an analogy. The human body has one off switch and multiple timers. The off switch is the brain stem. Place a round there and it’s lights out. Place a bullet anywhere else and you’re playing a waiting game in terms of physiology."
