100% with CompVest - every gun will have its supporters and its detractors. Walther has a good reputation. I haven't looked into the PK380 specifically, but would have no reason to doubt its quality. The most important thing is that you feel comfortable with the gun - in carrying it, in holding it, and in shooting it. If it fails any of these tests, you're more likely to leave it at home than to carry it and, importantly, practice with it. My husband always tells me (in the discussion of 380 vs 9MM vs 45): the gun you have with you beats the gun in the safe, every time.
Side note: I also have small hands. As well as relatively high sensitivity to recoil. I'm sure there are 9MM's out there that you can find that will be a good fit for you (I'm partial to the Kahr's - they have good size for small hands, and well-controlled recoil, YMMV). I also love the Sig P238 (380). Doesn't speak to your question about the PK380, but maybe more food for thought, either for your initial purchase or subsequent ones down the line.
