I have been a long time shooter of the P99C, both in .40 and 9mm and I recently purchased a PPQ SC. This is my first PPQ.
I hesitated because it looks so similar to the P99C, a simple matter of AS trigger versus the Q trigger and paddle vs button, right?
Wrong.
I can't tell you how much more comfortable TO ME the PPQ is in the hand, especially with the 15 round mag with sleeve. And the Q trigger, which I always thought dangerous in a carry gun, is perfectly manageable, and again, TO ME, better than the AS SA trigger. The break is different and more crisp. And as a Beretta shooter, the push button mag release is totally natural.
Again, these are totally individual reactions but they were interesting enough for me to comment.
I am totally happy with my purchase.
