I use Nate squared Tactical IWB tuckable. Very comfortable. Check them out. Just type N82 in your browser.
Check out UBG Holsters -- very well made!
I see a lot of websites sell holsters for the Bersa 380 but not the 9 UC Pro. I read a post that said that the 9 UC Pro uses the same holster as a Sig, but it didn't say which Sig. Anyone know?
I'm looking for the absolutely cheapest (inexpensive) IWB.
Check out the Tagua line of IWB holsters. I have several that I use that I got from Holster World on Ebay.
The Tagua paddle holster made for the Taurus 24/7 (PD2-120) fits my Bersa 9 UC Pro like a glove. Go to a shop with a good selection, because we just went to the display and tried holsters. Unfortunately it does not cover the hammer so it might not be what you are looking for... It does not chafe though! And Turp - look at the Passport line of nylon holsters. They're pretty generic, but there's lots to choose from and the one I got for my .380 T-Plus does just fine. It was $16
