Hitzy, do yourself a favour. Clean up the striker channel, striker and anything else you can find that makes contact or causes grit in the system. I was where you are, at first it was horrible, but now its very nice!! I like it better than any other striker fired pistol I have used. I haven't been able to actually fire a PPQ tho, so maybe that's better. It has a nicer trigger than some cheap hammer guns too. Some by quite a bit. As for accuracy, mine has been quite good. I was better with my Girsan, and my 1911, and other peoples CZ etc, but since I have concentrated and have had some instruction, it is just as accurate, if not more so than those. And not just in my hands either.
I have two problems with this gun. one is that the safety and slide release are just cheap stamped steel. Not a deal breaker but I would prefer something nicer. The second and by far bigger deal is the slide/frame fit. its loose and sloppy. You can see the slide move in relation to the frame if you squeeze the trigger nice and slow and pay attention. It has smoothed out considerably since new, so I am happy with that, but the slop is still there.
