What's for me not to believe? Modified said what I said, German parts, some assembled by S&W are the current P99 production.
I've handled side-by-side , but not shot, the "old" style German made DA/SA with proofmark on the slide, proprietary rail and funky curve in the trigger gaurd; the AS which is also DA/SA, has the "standad" rail, and a modified trigger gaurd to be more in line with what is traditional; and the QA which is same as the AS as far as I could tell except it has the same "SA" trigger pull for every shot like a Glock. The QA trigger seemed about the same as the AS second shot pullwould be. I believe the DAO is like the QA except every trigger pull more like the AS first shot -- but I'm guessing as I've never handled one of these.
My objection to the QA is that they left the decocker on the QA where it does nothing useful but could be a problem if "accidentally" decocked as the gun is completely out of action until the slide is (at least partially) racked to reset the trigger (like a Glock would be with a dead primer round).
If you don't like the QA you should dislike the Glock for the same reason -- "light" trigger no safety, (ignoring the QA decocker issue).
