Don't see this particular issue addressed, or maybe I missed it.
Got my new P10c to the range last weekend, and I had several times where it failed to go into battery, even when I gave it a push. I identified what was causing it. The square plate on the back of the slide, that retains the firing pin assembly... it isn't very secure. It wiggles up and down a couple of MM, and it was sliding down just enough to catch on the frame of the gun and stopping the slide from moving forward that last 1/4 of an inch.
if I pushed it up with my finger, it would uncatch and the slide would go all the way forward.
Upon closer inspection, it seems that this design allows that plate to wiggle around, up and down. There is no detent or pin holding it in place... the firing pin spring itself holds it in place.
After about 100 rounds it seemed to improve, maybe it had to wear away the rough edges so not it can't really catch... the edges might be rounded a bit so it might hit the edge, but has enough force to push past it...
Before I trust this for EDC, I am wondering if this is a known issue, if there is a known fix, or do I just need to keep shooting it to break it in and get those edges rounded off so that it can't catch and hang anymore?
Thanks!

call CZ-USA 1-800-955-4486 EX 336 ? Warranty

So that piece having a little play in it is not normal?
Can you check for me? Rack the slide and lock it back. Take your finger and see if that square has any up and down play to it. It?s not much, but it was enough to catch on the rear of the frame and stop it from going further. The part is plastic, so I am guessing that the sharp edge or any ?lip?has worn down a little so it is no longer catching.

I have heard of this from other shooters and am wondering about it. I would love to try the new CZC slide covers, (with suitable engraving, of course), and see if there is any issue.
-
I don't see anything wrong with the slide cover itself. I think it has more to do with how it is captured and held in place.
I think that some companies use a detent lock it into place that is separate from the firing pin. This one doesn't. The sleeve around the pin itself, is the detent. Well, that has some wiggle in it, because it has to move around freely in the firing pin channel so as not to bind... That looseness, makes it a poor device to lock the slide cover in place, IMHO...
Thoughts?

Here is a video of what I am talking about. Can you guys check yours and see if your slide cover and firing pin mechanism moves around like this?

That seems excessive. Mine don't move nearly as much.

Nor does mine, I'd guess mine moves about half as much as the OP's..

I just talked to the warranty deptartment, they said that I can send it in for them to look at, but that they currently have a 4-6 week turnaround time, plus shipping times...
What to do... live with it and see if it gets better or worse over time, sell it, or send it in and hope it comes back fixed in two months? LOL

Here is what is happening. You can see where if that piece moves down enough, it catches on the frame.

This happened to me yesterday. Here is a pic of my fix (hopefully).

The rear striker plate was already beveled in the center to slide over the rear of the trigger bar. I beveled the other areas to see if it cures the issue.
Years ago when I worked on 1911's the firing pin retaining plate would sometimes have to have a set screw drilled and tapped into the slide to keep it in place.

Just had this exact problem with my p10c at the range. Cz usa is sending me a new beveled striker plate. Hope it works. Has anyone tried any other fixes? I was thinking a silicone sealer might hold the striker plate in place, but still allow it to be removeable.
-
Flip it, when you play that slide cover, see if the striker and its housing should move harmonically with the slide cover movement. If not, the recess and the half moon is not "sit" properly or even broken. IMHO, mostly, it is not the angle that causes it, it is that recess and the half moon problem.
-
Bevel seems to work fine, although I trimmed mine in a plane parallel to the slide to remove enough material so that it couldn't snag on anything if it dropped down. It leaves a gap at the rear of the slide but I'm not going to carry it in to dirty conditions anyway. The replacement cover from CZ seems to fix it just fine.

SquireSCA, does your striker (firing pin) or striker sleeve move around when you move the slide plate up and down? Can you rotate the striker leg? The striker, the striker sleeve, and its attached safety should not be wobbling around in my opinion... In fact, the striker sleeve is supposed to be locking your slide plate in place!
A video of what the striker and striker sleeve are doing when your slide plate is moving up and down would be awesome!!!
I'm sorry your gun isn't working! Its always frustrating to wait several weeks to get a gun fixed... That said, your best bet is to send this guy off to CZ (perhaps after another video... :) ) to see what they can do for you. I personally would ask that they eliminate any striker sleeve and slide plate movement with properly fit or upgraded parts. If CZ can't make it right I would then ask them for a refund. I personally would not sell a broken gun without fully disclosing any issues it has.
-
The new slide plates are a little more secure but still wiggle and associated parts all move around too. I never looked into my new one too much, I did notice I can push the firing pin block over a little bit and the striker moves a little, looks like it is still blocked though.

There is a big chance when people re-installing the striker parts, the slide cover particulary, they simply push it hard without holding/ pushing the striker housing deep enough, since all parts related mostly made by plastic, the slide eventually/forcibly will be sit into its half moon, but I am sure it hurts either one or both of them. IF the half moon and recess are new/ good condition, the slide it will not catch the frame regardless it is 90 / 45 degree angle because the main thing is the "clilck" between half moon and its recess. I have seen on youtube, someone reinstalling the cover by holding the striker housing with hand while he pushed hardly the slide to back in its place; it breaks either/ both of those. Because of that, on youtube, all the "new from the box" p10c are perform almost perfectly 200 rounds...500....1000...2000...2,500...5,000 rounds etc.... (Hickok, MAC, iraq Vet, Honest outlaw, scooth, etc......)Is one/ two...of them paid by CZ maybe yes... but not all of them for sure; and many others p10c owners who never playing around with the striker parts or they do it properly, have never experinced this particular issue AT ALL. Again this is only IMHO.

Are you sure about this? I gotta disagree here. Never had the issue AT ALL is a little strong. I have "played around" with the striker parts plenty, and have installed the cover properly, gotten the striker seated in the cover properly, and could STILL push the cover plate down enough to catch on the frame insert and make it hang. No, I haven't damaged any plastic parts. It only happened ONE TIME while firing the pistol, but I could easily duplicate it after seeing it happen one time, so I fixed it. I trimmed the cover plate and don't expect to have any more hangs.
If and when CZ offers a modified striker housing and cover, I may replace mine. But I don't have to and mine is fixed for now. One time mine hung before I fixed it. One time. Looks to me like it is a random occurence because the cover plate movement has to correspond to the slide movement and the cover plate and housing are not pre-disposed to move down on their own. Guns that haven't been damaged by buggering up the plastic parts might just hang eventually, just like mine did. I don't think it is happening just because people are messing with their guns.
The only "big chance" I see here is that CZ will design the parts a little differently in later versions. That's all. No big deal. So where is my optics ready 5" version? :) :)

...Is one/ two...of them paid by CZ maybe yes...
Just because this chestnut was raised quite violently on my YouTube video page I must note, I am not nor have I ever been on the CZ-USA pay roll and they do not own or manage this web page. They do sponsor us with giveaway donations, but while I would LOVE an extra paycheck, I am not an employee of CZ-UB, CZ-USA or affiliates.
We now return you to your regular scheduled thread.

I don't think any of those mentioned are actually "paid" by CZ. Their reviews are what they are and should be perceived just like any video review. There are plenty of vids on youtube touting the P10C's issues real or imagined just like there are plenty of vids touting pretty much any other firearms issues real or imagined.
-
I wanted to say all those the p10c reviewers are NOT paid, but I do not know; therefore, I wrote "......maybe....". My point about that partiucally one is ...brand new from the box do "not" have that "problem" base on those youtube reviewers.
