On Breda's recommendation I bought a pair of these holsters. One small holster for the Bersa and a large one for the P6. My experience thus far mirrors Breda's. The holster for the P6 is extremely tight. I can draw from it just fine but it's a bitch to re-holster. It's leather though, so I've no doubt it'll loosen up with use. So far they look to be pretty good IWB concealed carry holsters, especially given they were ~$25 each. What's really nice is they can be worn IWB or OWB at any position on your waist and attached with a clip or belt-loops.
Here's the holster. It conceals fairly well, especially the bersa, which is so light I barely feel like I'm wearing it.
