my experiences with it...
i owned one for about 3 months. picked it up right after they first came out (not the first edition gray ones mind you...) because i fell in love with the size and pointability of it. im not sure what the deal with mine was because i had a lot of FTE's with it. i used a ton of different kinds of ammo, i cleaned it up real nice every time i went to shoot it, tried both of the magazines it came with, etc. mine still had the same problems. it seems almost like the drastic angle of the ejection port was catching the rims of the casings before they had a chance to get fully tossed out to the side. nothing i could do would fix it (in my limited knowledge of cleaning and take-down procedures at the time) and the issues seems to average about once per magazine for me, with no pattern as to where, be it first round, last round, etc...
-i finally ended up trading mine in for a pretty good deal on a kimber SIS ultra (i couldnt pass it up), but i followed a lot of reviews since my early run of the PPS and no one seems to have any real sufficient gripes about them. maybe i just got one that slipped through the QC cracks.
