So, I would just like to double check for posterity... So far TomJ and I are the only ones to actually pick up a P-10C to see what the issue was, and I'm the only one to actually diagnose it to the point of failure
My guess is that there won't be a Gen 2 any time soon. The fix for this, will most likely be CZ making the rear plate slightly over sized so that it can't slide down if it is inadvertently unlocked. You know, just like S&W did.
To recap:
This can only happen if you displace the striker to the left, which takes actual conscious force from the shooter. You can't wobble the gun hard enough for it to displace on it's own. But again, displacing the striker is not itself what is causing the failure.
This can only happen if after displacing the striker to the left, the slide is allowed to slow travel forward. Normal speed slide travel realigns the striker and allows the slide to close before the cover plate can displace.
I tested this dozens of times last night, even going so far as to dissemble the striker assembly as alluded to in my prior post. The only time I could make the rear plate come lose and induce this failure is if I intentionally displaced the striker and intentionally slow closed the slide. Just like he does in the video. The fact that no one else seems to notice him baby closing the slide makes me wonder if there is any intent at honesty here or just another "OMG, THIS GUN SUCK" circle jerk. Seriously, does no one else see his left hand?
For anyone else out there that actually has a P-10C, lock the slide to the rear. Displace the striker to the left so that it clicks into place. Release the slide with the slide lock. I guarantee that the slide goes into battery and the rear plate is locked in place as it should be.
