You will find this thread turn into a claiber war very fast. There are folks that will defend the 380 till the bitter end & folks, like myself, that will never trust a 380 for self defense.
I have faith in FBI testing that led them to conclude that the 380 is not acceptable as a defensive caliber since it will not penetrate to their 12" minimum in ballistic testing.
Other folks will run to the argument that something is better than nothing.
Still others will scream that "Guns are bad... ummmmkay..."
Do your research, shoot a ton of weapons & decide for yourself since most of the data you will find on the internet can be slanted to fit the person who is posting it anyway...
