Picked one up a couple weeks ago in 9mm. Of the double stack polymer guns it is my favorite. Comfortable grip, PHENOMENAL trigger, easier slide to disassemble than my Glock, and did I mention the trigger?. I have shot Sig(not sure of model), Glock 23, Beretta 92A1, Smith M&P, Springfield XD and the PPQ M2 for double stack autos, and the only one I prefer to it is the Beretta. And I probably like the 92A1 the most because of the heavy weight for quick recovery, but that DA/SA isn't ideal. I didn't care for the crappy XD trigger and top heavy feel. Really don't remember the feel of the Sig since it was the first handgun I ever shot and didn't have anything to compare it to. Glock is great and never ever ever malfunctions and the M&P was a great one also. My only gripe on the PPQ is the slightly high bore axis, if it was just a little bit lower it would be a hands down winner for me. Magazine release location and size on the M2 is flawless, the slide stop is awesome, and the reset on the trigger is crazy short. Those PPQ's are a commonly overlooked gem, I highly recommend it.
