Trying to be objective about this, or as objective as possible -- is there really an answer to the question? Isn't it always "it depends?"
People have been dropped by a .22.
People have been shot with a .45 in the chest and kept fighting.
People have gone down faster with pepper spray than with bullets.
Others are stopped with one shot of any caliber. Some stop fighting and run like hell because they think they've been shot but haven't.
People on drugs have been shot to pieces and kept trying to eat someone because their brains are fried and aren't registering pain.
About the only things we really seem to "know" is that .380 performs OK-ish in certain gel block tests. 9mm performs better. .40 and .45 typically don't perform much better than 9mm, but that can vary.
Some argue that the real question should be "Are handguns themselves adequate for self defense" and would say the answer is "no."
I really think the only answer here is to get the "most powerful" thing you can in a size you can carry regularly and shoot accurately with, and then practice and hope like hell you never have to find out.
