I have a Bersa .380 and it has proven to be reliable and useful as an instructional aid. However, it would not be my first choice of a EDC .380
There are a whole lot of .380s out there that I think are engineered better and made of much higher quality materials, but they are also much more expensive. If all you can afford is a used .380 in the $250-$275 range the Bersa might be a winner in that price range. But, with that said if you can bump your budget up into the $350-$400 range there are lots of fantastic choices from Ruger, Kahr, Glock, etc......
It is your life, but the reality of a limited budget is a huge anchor that most of us have had to deal with before.
