I carry that one too in a little nylon pocket holster to keep it from getting dirty. It works in shorts or any pants you want.
Rumor is that KelTec is coming out with a single stack 9mm that's almost the same size.
That'll be fun! The 380 pops pretty big, though. I run Speer Gold Dot through it and it kicks pretty good. Darn accurate little fella, though...
