It's 12 rounds flush/15 extended. And the P365 is specifically appealing to me for having near duty pistol capacity but it's as thin as a 6+1 G43. I'm not a cop any more and frankly the idea of carrying a traditional double stack brick in my pants has lost it's appeal when guns like this exist. If the metal G48 mag comes to fruition I might opt to go that route instead but I suspect the safety'd 365 will be available first, plus aftermarket glock mags don't exactly have a great rep either. The rental p365 at my range has been utterly beat on and hasn't broken yet, so I'm willing to T&E one for personal use.
