I really don't think so but I dont have any NAA mags to try in my P3. The top profile of the NAA magazine dosen't look anything like a P3AT's. I know that "Promag" lists a 10 round (and 15?) for the Kel Tec. Be warned that most here at KTOG will tell you that Promag's quality is usually lacking so buy one at your own risk.
