I bought my Bersa .380 CC about a month ago and, since then, have tried 7 different pocket and IWB holsters (OK....so I've got OCD!).
I really like the de Santis "Nemesis" pocket holster. For regular slacks (like Dockers or such) with full sized pockets, it's a comfortable fit and is undetectable. It also provides a smooth, quick, draw.
But, ultimately, it comes down to what I'm wearing. In summer, here in Florida, I wear shorts and t-shirts a lot. The pocket holster just doesn't do as well with this type of outfit.
My current choice of IWB is the Blackhawk Nylon model. It's coated with neoprene on the outside so it doesn't rub or chafe your body, and the neoprene is sweat-resistant (unlike leather).
The inside is a 'grippy' sort of nylon that keeps the gun in place at all times, yet the draw is soooooo smooth and quick. Sounds contradictory, I know, but you'll see what I mean if you try it!
I understand your hesitancy about an IWB holster and comfortability. Several of the ones I've tried were simply annoying. The Blackhawk, however, is very comfortable and, after a few days of carry, you hardly notice it. I wear it in what's called the "appendix" carry and the gun is invisible, even with only a thin white t-shirt over it. Finally...it's really inexpensive ($12 - $20)!
Hope this helps....
