You are right about no gun being ideal for a meth head. The chances of the average person ever meeting and having to deal with this kind of a problem is like winning the Power Ball 500 Million Dollar Jackpot, 1 in 292 Million. So in conclusion, there is no reason that a 380 ACP will not be a good self defense gun caliber. I feel safe when I carry mine. But I also have bigger guns for different occasions.
