Yesterday I ended up buying a P99C QA in 9mm. Lately P99c have been as rare as hen's teeth around here. Back late last year there were a bunch of them around in all variations and calibers, and then about a month or two ago they dried up. I've even seen less on the Net and never very many to begin with. I wanted to buy this gun in person if it was used, which this gun is (but mint), as it is meant for carry.
I actually had my choice between a new .40 caliber AS and the used but minty 9mm QA for $150 less. My full size P99 is an AS so AS was my first trigger choice, but the QA was a close second. I'm very used to the QA type trigger but it would have been nice to match my full size P99. The main decider was 9mm over .40. The trigger I could live with either way. Plus, saving $150 and still having a "like new" gun is the A Plan.
Another thing that I like about the QA is that it also has the decocker. I know that it really isn't meant to be used as one other than field stripping, but I still find is very useable. While I will carry the gun loaded and "cocked" (or, half-cocked?), I do like to have the ability to step the gun down to a de-cocked condition in various settings. Plus, it is very quick and simple to return the gun to firing condition with a dead minimal (1cm) retraction of the slide. In any event, the key is to keep you finger off the trigger unless you want to go bang. Some folks freak at the notion of a lack of a manual safety, but I just treat the gun as if I was carrying a revolver.
As to the trigger pull itself, it reminds me somewhat of one of my favorite triggers, the double action only trigger of the PT111, a trigger that I do very well with. If this was going to be a target gun I would consider otherwise, but I'm anticipating far more than acceptable accuracy for what the gun is meant for.
Walthers are addicting, this is my fourth (P99, P22, P1, P99C AQ). Next will be a Walther PP Super and then hopefully a P5. I'm working up to the P88!
