Bersa is a very well made low cost gun.
I have, and carry, the .40 XD Subcompact and love it. It fits my hand well, shoots accurate, eats any ammo I feed it and has never once had a FTF, FTE or jam. I have close to 15,000 rounds through it.
If your wallet lets you afford the XD it is, in my opinion, a better gun. If you're looking to spend less maney the Bersa is a good gun as well. Best thing you can do is find a range that rents guns. Both the Bersa and XD are popular guns and will probably be available for rent. Shoot them both side by side and determine which one you shoot best. That is the better of the two guns for you.
