I have the DeSantis "Sof-Tuck" IWB holster for my 380cc. Works fine, good fit and doesn't break the bank price-wise! Good luck.....
Welcome to the Bersa Firearms Forum !! IWB / OWB ? I use High Noon holsters... http://www.highnoonholsters.com/Product_Line/product_line.html
I have a couple of old Bianchi soft leather IWB, with clip and thumb break release. I like them cause they keep the gun in even when crawling in the brush, climbing, or bending over. Gt them used. Both work well with Walthers and other similar medium frame autos.
Check out "SneakyPete.com" Have one and love it. I also have a www.pocketholster.com, (their made for a Walthers PPK but my.380 cc fits in very nicely. it's not good if your wearing tight pants but wide rear pockets work very nice. It gives the impression of a FAT wallet so wear a shirt over it.
