The PK380 is a totally different animal to the PPK or PPK/s.
If you get one, go to the auto parts store and pickup a valve stem removal tool (the one that look like a screwdriver). Polymer is okay for frames, but little tools made of polymer have a habit of breaking for me.
I prefer the PPK/s over the 380PK. The PPK/s is better for EDC for size, but not weight.
