The LC9 is a little bigger, but probably a better choice, IMHO.
I have an LCP. Great pocket pistol. The 380 is a little weak for my taste, but is better than nothing when it’s the only thing that I can fit in my pocket. I prefer my 45 Warthog, small enough to fit some of my shorts pockets (have to watch that they don’t wind up around my ankles, tho).
