Depends on how you really want to carry it. In the summer when I am wearing shorts, I pocket carry. When you do that it is all about size and weight. If you don't want your shorts dragging down or have people wondering about that bulge in your pocket, you are really looking at the Ruger LCP/Kel Tec P3AT/Tarus 738, all in .380. Anything else is going to be larger and heavier. This link has a good review of all three:
