Nothing wrong with the gun, I recently purchased a P30S and the prior owner of the forum, JS has one as well.
Other then HK specific forums, HK is largely unrepresented on gun forums. For the most part the biggest "fault" of HK is that they are more costly than other polymer offerings and therefore less popular.
The forum owners also own a HK Forum, there's a link at the bottom of the page. Go check out the P30 threads over there.
