I have the full size 9mm PX4 Storm and I love it. I've had no problems with it at all, but a couple of my friends did. The three of us went to the range and my friend, who had never fired a handgun, had several FTF's and FTE's. So did his son. I think it had to do with not seating the magazine properly. That's the only thing I can think of. When I fired it, it was perfect and it's never happened again. I'm not sure I'd want it as a carry, thinking the sub-compact would be better, but that's just my preference. I have a Springfield sub-compact and two Sprinfield EMP's, a 9mm and a .40. I like them better as my carry's just because of their size. If you dlecide on the PX4 Storm, I think you'll like it very much. It's accurate, dependable and just plain fun to shoot.
