I tho't it may be useful to show a couple things that I've noticed.
I carry the Firestrom 380 more than the Bersa. I've had the Firestorm much longer than the Bersa's that I have. Cost is relatively the same.
Both are made by the same folks in Argentina. Bersa's are more common for some reason. I believe that Firestorm is made for some European or SA police force or some such. Can't remember.
The things I like about the Firestorm are the lack of a trigger guard perch for your finger. I don't grip my guns with the week hand's fore finger gripping the trigger guard. Firestorm has a rounded trigger guard.
Also, the sights are much larger on the Firestorm vs the Bersa. F/S has a large white outlined rear sight vs two small white dots on the Bersa's. Older folks may appreciate the former. Altho, I rarely use sights. I'm a point and shoot gunner. I had some courses at Smith and Wesson that trained us to not use the sights in an 'encounter', but rather point and shoot. Works pretty well if you practice.
Here are a couple photos showing some of the differences between the Bersa and the Firestorm. They both cost the same/same for the most part.
