Agreed 100%, I'm liking mine a lot too. It's at 800 stoppage-free rounds so far, typical HK reliability.
Things I like: Reliable, accurate, good trigger, robust optic mounting system. The CA "features" are well designed, no powder residue out of a hole on top, instead it's a tasteful modification to the extractor. Simple mag disconnect design, again no major changes just a modification to one existing part and it doesn't add any complexity to takedown. And one thing I don't see talked about enough, no need to pull the trigger to field strip, that's a nice touch. And the design contributes to ease of concealment.
Things I don't like: I'd prefer a more aggressive texture on the grips, and extending higher up the sides (I realize this is to some extent personal preference, and it's easy to fix with grip tape). I wish there were an in-between size of iron sights offered on the web store, taller than the low sights but lower than the tall ones on the long slides. Again an easy fix if HK (or the aftermarket) so chooses.
A couple of comments on the VP vs the PDP: I agree the PDP trigger is "better" in a target or competition context. But I think the PDP trigger is a little light for carry, and prefer the VP trigger for that purpose. Not a surprising design choice given all the mil and le sales by HK. I also prefer the PDP grip shape. Where the PDP loses me is the massive angular slide which is fine for duty use but really difficult to conceal without printing; the snappy recoil, which can be tamed with the proper grip... but, why? (again this may be an advantage in competition, because it's also back on target really fast, if ones fundamentals are solid); the less robust optic mount system, which leaves a small opening into the striker channel at the rear and uses smaller M3 screws; and the near absence of parts support by Walther. I gave up looking for spare 10-round mags after six months. HK in comparison may not have everything in stock at any given time, but I haven't so far had to wait all that long to get anything.
