I think we can all agree that a .380 isn't the best choice for self defense...I do feel it has a place in my arsenal.

There are times when carrying a larger gun isn't practical. I'm happy to have my LCP for those rare times. It is reliable (when I do my part) and I shoot it well at reasonable ranges. The 90grn XTP does well in my informal tests also.

My general rule is to carry the largest revolver I can conceal. Usually that's a j frame but when the situation allows a medium frame .357 is my preferred choice.

We all walk different paths...what works everyday for you may not work for me. The micro .380's allow some of us to go out armed when we might otherwise have to go empty handed.
That's a far worse choice than having an "underpowered" round.
