I've encountered ZERO problems with my XDS. Over the last week, I've put 350+ rounds (of all types and brands) through it, 50 today and have not experienced a single hang-up. Interesting thing happened at the range today while I was waiting...a guy came in with an XDS he had just bought, said that he can't ever shoot it cause it always jams on him. Said it jammed on him the first time out with it and jams every time. The range official took it on to the range, fired 5 rounds in rapid succession, dropped the mag and fired 5 more and had no problems. Don't really know how it turned out but I was actually surprised to hear he was having problems with his XDS. Maybe a defective gun maybe bad mags, whatever it was, I hope he gets it figured out so he can enjoy this firearm as much as I do.
