Thanks guys. It is an earlier model P99 (is not marked with AS or QA on the slide) and shop says the trigger is essentially AS. Comes with two magazines, the original case, two-dot rear sight, a hi-viz front sight (plus a couple extra regular visibility front sights), and all original paperwork/owner's manual.
Went back to the shop Tuesday and took a long second look, ran a snake through the bore a couple times and checked it out with a bore light... seemed to be pretty good shape. Asked their best price... they said $425, which I thought was a pretty good deal. So I decided to buy it
Picked it up Friday, gave a good cleaning (really needed it) and she looks beautiful! Will be a while before we get to the range though... sigh.
