Good Choice
I have one with a 6" barrel - not a pocket gun any more, but accurate, pleasant to shoot and reliable. It is kind of an odd-ball (similar to the Walther PP Sport or Beretta 71 (I think) with the longer barrel).
It has an internal lock (but I have never engaged it), hammer-drop safety, and a magazine disconnect. It is a very good teaching gun for my spouse. The finger-groove soft rubber grips fit her hand very well.
I am looking for a .380 as a companion, but the .22 is radically less expensive to feed and will be shot a lot more (so far, mine digests everything). I got mine off of one of the auction sites and I was pleased with the price.
The downside of the Bersa .22 is that spare magazines are really hard to find. I may have picked up the next to last one in the US after a very wide Google search. On another forum, I gave the address to a Bersa .22 shooter and he may have picked up the last one. (Ivanhoe Outlet)
There is a Bersa forum if you want to get other opinions.
Hope this helps in your decision.
