To me the key is whether you are going to carry in the front pocket. The J Frames work better there, particularly the no-snag ones.
Bersa--Thunder 380 I presume--would work fine otherwise, and be less painful to practice with. I would choose the regular Thunder over the 380CC I once owned, because the regular one has better sights for more accuracy, and a longer grip tang for shooting comfort.
As someone noted, the Kahr CW9 is about the same size as the Thunder also. $350 this weekend at Cabelas.
