The .380 is likely to be as effective as any other round in the sub-caliber class. Like the .22 or .25, it can and does kill people, but per the quote above, the object of carrying a defensive weapon is not to stack up bodies like so much cord wood. The purpose is to stop threats and save your life.
While the .38sp and 9mm are generally held to be the minimum caliber for a lethal defense, that does presume a worst-case scenario. Statistically, if you have to use your firearm in a defense situation, just pulling it out will solve 99 percent of your problems. Gary Kleck's stats actually put the number at something like 99.8 percent.
This is why you don't open your newspaper and see a story about a concealed weapon permit holder killing a bad guy every day. It happens, but not very often.
If you do pull your weapon and fire a round, most people will run away, dive under tables, hide behind cars, etc. Up to this point, the .380 will work as well as anything else. Really, it's only in the extremely rare event that a person is trying to kill you and is ignoring the bullets and walking straight into your gunfire that you want a bigger caliber. The "penetration" and "one-shot stop" arguments are more appropriate for law enforcement personnel.
