It is absolutely a good round. Anyone who says "any gun is better than no gun" believes in the concept than a .22lr carried is better than a .45 in the safe. Therefore stating, a .380 is appropriate as well. I generally carry 9mm, but while pocket carrying or for thinner shirts, I carry my LCP. Just picked up a PM9 today, so might be pocket carrying that and selling the LCP but think it's a wonderful carry piece.
To me, it's nice to not feel like you've got a brick in your pocket, and then there's mowing my ditch when it's 100 degrees out and being dressed comfortably. My 357 would be dragging on the ground with my shorts between my ankles. NOBODY wants to see that!
