I wouldn't carry a 380 personally. IMO if I'm looking for concealment. I'd carry a snub nose 38 with hot loads or even better a snub nose 357mag.
There seems to be a lot of opinions but is there anyplace we can find real data. I realize there probably has not been a lot a testing of stopping power on badguys, but I would like to see a compilation of data on velocity, energy, and any other characteristics that would support a decision on what to carry. Does anyone know of a website that has this data?
Carrying a .380 with some good loads, I feel is the minumum I would feel safe with. I usually carry a .44 spl with hollow points and in the summer I carry a S+W 638 with .38+p. I never cared for the .380. Mainly because of the price of the ammo.
