technology and viability
If this was 30 years ago, I'd say that .380 wasn't the best choice of round. Then again, as my friend would ask if I'd mind catching one so we could prove how ineffective it is... My declination of services to his experiment was usually testament to my ultimate belief that "yes" a .380 is effective enough to defend one self with. Fact is, munitions technology has vastly improved. We commonly have smaller rounds being pushed faster with less pressure, and thus the increasing the potential of that round. Of course I'd prefer to have the stopping power of my 7.62x51 NATO in a smaller handheld package, but realistically thats not going to happen, and not what handguns are about. Europe used sub 9x19 rounds for many years with exceptional results, and had many chances to upgrade. The little .380 automatic has at last prooven it is a viable round worthy of trust and service. Add to that the modern high performance self defense round formulas being applied by various companies, and you will be projecting a very real deterrent out that little barrel. Of the many many test i have seen (and others personally done) I'd have no problem with any modern .380 in a performance (not saying +p) load.
