Whenever anybody questions the capability of my .380 for self defense, I offer to perform the be all, end all test to resolve the question once and for all.
I tell them they can wear as many layers of clothing of their choosing and stand 50' downrange. I'll empty all 7 rounds in their direction and then we'll see if indeed, the .380 is not a good self defense caliber.
I've yet to find anybody willing to disprove that theory.
So, the take away from this then is that the bad guy will stand perfectly still for you while you empty a full magazine of .380 into him. I guess the idea of moving never entered their mind.
About all your comment proves is that people do not like to be shot, regardless of caliber size.
