I have a PPQ brand new and only proof fired at the factory, and took it to the range for the first time this Sunday and shot 200 rounds of AE/Fedral 115grain FMJ.
My only prior experience with pistols is with the range's rental Glock22, and I am by no means an expert so me showing you guys my targets wouldn't really be of any use since I suck with everything equally.
I am not sure why, it's really only speculation as to the cause, but in my first 20 rounds I had six failures to fire. I shoot one, second cartridge chambers and I pull the trigger and click nothing happens. I wait, eject mag, empty the chamber and inspect the primer and it has no mark on it at all. Complete nonstrike from what I could see. I put it back in the mag and shoot two more and then it happens again, same thing with no visible strike on primer. Round goes back into the mag, shoots fine but the next one fails to fire as well. Rest of the mag shoots fine. The second mag has three in a row, but each of them shoots fine the second time they are put in the mag and chambered. Number 2 and 3 from the second mag show light primer strikes. I ask one of the ROs to take a look at it and he shoots 2 rounds with it and it works perfect.
The next 180 rounds shoot fine. A few of the primers show really weird primer strikes, looks like an oblong splash rather than a single impact mark. However I searched the other brass piles nearby and a whole bunch of other people's ammo is looking the same as well. Would that be caused by high pressure? I'll try to get some quality pictures of my primers tomorrow, because some of the strikes look kinda funky.
So, might have just been growing pains. Maybe I missed some grease while cleaning, or maybe it was being influenced from the spirit world. Maybe gremlins.
After the initial troubles the gun shot fine, felt great, and clicked and banged as appropriate. I'm still working on my grip and stance and all that stuff so my groups suck beyond belief, but I'm hitting paper at least. My theory is that maybe I had some grease/lube/hairs or something on the striker and that was causing it to gum up. Entirely possible that's it, because the gun worked fine after it got warmed up. I'm still detail cleaning it looking for possible evidence. Could have easily been a case of hydraulic firing pin.
If someone in Edmonton wants to get hands on it, let me know and I can meet up with you at Phoenix. I'd appreciate a second opinion.
