Well, I've had a 380 Bersa a little while. I got it in the beginning of the summer. It fired as well as I would expect a small pistol to fire. No jams etc.
You talking about getting a Sig Sauer. I have two (226 and 229) and want a couple more. Even my 1911 addiction can't keep me away from my Sigs. You can't go wrong with them.
As to the reliability of my Bersa...It does pretty well. I don't know if I'd advise one for a primary protection piece.
