I've no complaints. Lotso fun to shoot, makes me wanna hurry up and get a chl so I can throw it in my coin pocket. Not very comfortable with the 6rd mag, but it comes with a 7rd so it's really versatile. The only complaints I've heard so far are towards its trigger. But all it's on par with my g23 so I dunno
I had no problems whatsoever firing the XD-9 subcompact with the stubby mag and my pinkie just dangling loose or cupping the bottom of the magazine, so the 6rd magazine on the PPS doesn't seem like a problem. I'm not exactly a small guy, so I don't think concealment is going to be an issue. Heck, I could probably comfortably conceal my G17 with the right holster and wardrobe.
