I have a Bersa thunder that I carry when I need something small. I love the decocker and the easily manipulated safety. Reliability was an issue only once, when I tried a couple of magazines of Wolf ball ammo. Normal carry is Federal self defense .380 hollow points, which function and feed very well.
I find it to be as accurate as I can shoot. Snobs may laugh, but 8 rounds of Federal .380 JHP's at close range are not usually survivable.
I have a Bersa in 380 it is spooky accurate. One time I thought I would scare a stray dog away from my wife's garden from 90 yards. Figured if I aim right at him from 90+ long paces the inaccuracy of the firearm would just get a bullet close. The dog went down dead with the 90grain Hornady hollow point working perfectly. The dog was a German Shepard size mutt, one of hundreds the city people would release in the wild around our home.
Sad note is during the ten years we lived there I had to shoot over 700 stray dogs the kind people of the city of Albuquerque would abandon in our area. Animal control stopped responding after the first year of calling them. Over that period of time I know what works and what does not work with backup guns, carry guns, duty guns, and rifles and shotguns. The 380 hollow point does work.
Bersa is the most over looked gun on the market. I carry a 380 thunder as a bug, as of sunday. my son carrys a 9mm as his primary and a 380 as his bug. My wife just got (sunday) a 380 concealed carry as her primary. in the last two years my family has shot at least 3000 rounds through the 380s. we all bet our lives on them. (except my daughter. glock 33 primary, phoenixhp 22 bug) But ive always thought she wasnt mine.
