I've been having a minor problem with my P-10, One of the coil pins in the top rear of the frame keeps walking out, the pin that's walking out is the one closest to the mag well. I called CZ-USA, and they sent me a link from their warranty page on their website I filled that out and I was told when talking to them on the phone that they'll send me a Fed- Ex label and all I have to do is box it up and send it off. They told me they want to take a look at it and see why the pin keeps walking out. I'm hoping this dosen't take too long... Other than this, I've been having a blast with it.
