I carry a Sig 232 most days which is about the same size as a Bersa, and I wouldn't call it a pocket gun. Coat pocket, sure, but I think it's too big for a pants pocket. Sure it fits in my pants pocket, but it takes up so much room it is hard to draw and prints like a mother.
Also I know that the overall length of the CC is a 1/2 " shorter than the regular Bersa Thunder, how interchangeable are the holsters?
If all else is the same but the barrel length they should be interchangeable, as in the shorter CC should fit any holster for the slightly longer model.
