It's been discussed here several times (search for P99QA). But, the bottom line is this:
- It's about 5.5-6.5 lbs, constant force pull. Some have said it's "Glock" like, having owned a Steyr M and S series, I would liken it more to them than a Glock. The Glock trigger is a little more "mushy" whereas the QA and Steyr trigger has a take-up and then snap.
- I haven't actually shot one, but I've handled and dry fired them at the Shot Show.
- I own several standard P99s and the DA trigger pull is long and about 10-11lbs, with the SA trigger pull being short and light at about 4-5 lbs.
- The QA trigger does not move as much as the standard trigger.
I plan on obtaining a QA pretty soon, so I'll be able to give you shooting impressions when I do.

James
