1st time I shot my PC Shield it was doing the same thing. Couldn't get thru a whole mag without it happening a copy of times. Went home cleaned it very very well, lubed it up and racked the slide by hand a few hundred times to break it in. Could actually feel where it would hang up at. Next trip to range lubed it up very well, including corners of the barrel and some along the barrel.
I have put 500 rounds thru her since that 1st day and she's a sweet shooter now and hasn't hung up since that 1st day.
