I've owned a PPK/S (not the PK380.) I liked it at the time, for what I bought it for. That was a long time ago, and it has since gone by the wayside.
Currently, I own a Bersa Thunder, and could not be more pleased with it. It has readily digested every round I've put through it, including stuff from 2 to 20 years old, mixed up in the mags. As I've said before, if ammo for it was as plentiful and inexpensive as 22LR ammo is, this would be my most enjoyable gun to shoot. It was my EDC until I came across a good deal on a Kel-Tec PF9.
Now, all that being said, you said you were buying the gun "today" when you posted, and that was two weeks ago. So, which way did you go?
