I own 2 Storms and they are excellent pistols and I'd highly recommend the Storm. I've heard the PPQ has arguably the best stock striker fired trigger on the market. Do you prefer an excellent DA/SA or an excellent striker fired platform. I prefer Beretta's DA/SA for CCW. If you CCW, or even if you don't, I'd give the PX4 Storm Compact a very, very, hard look. Others will have to weigh in on the PPQ.
