I have put about 700 rounds through my P99 QA .40
I haven't had what I consider a problem. Just a couple of nit-picks.
... I had one failure to feed early on, but it was an obvious limp wrist shot. Since then no problems.
... the blueing (or whatever is used) on the barrel shows a bit more wear than with the glocks or hk's that I have owned. Doesn't look like its affecting anything materially, just the color.
... I had to file down some of the sharp edges in the plastic around the mag well. There seems to be more sharp edges compared to glock or hk.
... final nit-pick - no Insight M light available yet. I sure its only a matter of time, but none that I know of out yet except for the clumsy one that Walther makes that fits under the lazer.
.... final, final nit-pick - I still have not been able to determine if you can drop in a 9mm or .357 barrel in your P99 like you can with a glock.
Overall, very satisfied with my P99 QA. I can honestly say that my search is over for a house gun. And, I have tried everything out there, spent alot of money & time.
