Hello. In my observation, the majority of Bersa 380's run fine and work fine. I've got about 3500 shots through one with no problems and am still on original parts other than the recoil spring. I do not think the pistol is offered in .32 ACP.
I agree with the idea of not going below .380 ACP for "serious" purposes.
Before retirement from police work, I saw shootings in which the .380 worked but others where it failed to "stop". The most "interesting" of those involved a drunk who was sitting right on the railroad tracks after having been shot in the leg (I don't remember which) by a dude using a .380 loaded with ball. (I don't recall the brand) The drunk's femur was broken. He was in no particular pain but was also pretty well "poached" with alcohol.
