I own the P99 QA 9mm and I love it, in the beginning I wanted the AS model which I own a fullsize of in 9mm but I settled for the compact QA once I saw one in a local gunshop.
Main reason I bought it is that around these parts the P99 compact has been rare as hen’s teeth so when this one popped up I purchased it w/o hesitation.
I am pleased with it, she is accurate as hell for a small compact 9, the trigger is nice (think LEM) holds 11 rounds and fits my hands nicely, easy to conceal. I carry it in a DeSantis OWB leather holster.
