Personally, if I was going to go with a .380 it would be for pocket carry. In that case, it makes much more sense to go smaller and lighter. The P3AT (or Ruger LCP) is lighter and smaller than the Bersa. So, why go with the bersa? If you're going to go IWB, than the Bersa isn't much easier to conceal than your Taurus either I wouldn't think. What would it's purpose be?
I will own a P3AT or Ruger LCP in the near future. I don't see any Bersas in my future. There are plenty of people that have no issues with the Bersas at all, but if I was going for a gun that would for the most part be a BUG or an ultra-concealable type gun (the only reasons to go with a .380 IMO), than it would be the smallest possible (Read - P3AT, LCP). Just my .02
