I can only give you my experience with holsters, evertone is different.
Over the years I have found that comfort and fit and stability is something you'll pay for.
If you like inside the pants holsters and were to buy a quality leather holster that was made for your Bersa, you would really notice the difference in comfort and fit and how stabil your gun would feel.
I also have a couple of Uncle Mikes products, can't beat the price, but they can't compete with the holsters I paid more for, especially when carrying all the time. Now that is my opinion, and I'm not knocking any brand, I have a bunch of holsters from trial and error over the years.
As far as what I use, usually either inside the pants or outside the pants depending on the season/weather/clothing...strong side carry, high quality leather.
I won't bother to give name brands, there are many good ones, just do a search on the net and see for yourself.
It will cost you a bit more for comfort and fit and stability.
