Pretty good review. The one thing missing is discussion of reliability but that may be something that takes a while to evaluate.
I haven't shot a PPK/S so I cannot comment on it. I do have a Bersa and carry it often during the summer so I have confidence in it. Just because something is not as finished or refined does not mean it is unreliable. I don't carry the Bersa because it is cheaper (that's a bonus). I carry it because it is reliable and I like the way it carries and shoots. It replaced a Kimber Ultra Carry II as my summer carry weapon of choice because it is more reliable.
