I have an Uncle Mike's IWB holster for small autos, size 1 IIRC. I bought it when I got my Bersa as a stop-gap until I found a "real" holster. It's held up ok, however, and it's plenty comfortable for me. They're like $4.95 or something like that at Gander Mountain, so I decided that if I ever wear this one out I'll just buy another one.
Until you buy a quality piece of leather for it, you might want to give it a try....
