P10c striker assembly upgrade
« on: November 26, 2018, 11:27:40 PM »
Does anyone have photos comparing  the old and new P10c striker assembly?  I’m interested in seeing what was done in regards to the rotation issue that some experienced.

I don’t have photos handy, but what CZ did was to add a rib along the right side of the striker housing and mill a mating groove in the slide.  This rib and groove eliminates the ability of the striker to rotate.

CGW has a fix in the works that does the same thing, but in a slightly different manner.

If you have an original P10C and it’s still under warranty, CZ will upgrade yours to the new style if you experience a failure.  You have to be the original owner and have receipts to prove it though.  For the other 80% of folks with early P10Cs, CGW has a fix in the works that will accomplish the same thing.

One thing that I’d recommend is to avoid a lighter striker spring on the P10C.  I was running a lighter striker spring when I experienced the failure in my early Gen 1 P10C.  I don’t know how much that lighter striker contributed to the failure, but it most certainly took pressure off the rear slide plate, which is what prevents rotation in early guns.

Or you can run it.



Original FDE, the one that came without night sights, very first gen, has well north of 3K rounds through it, no failures.

What would be the failure?  Is it the rear slide plate slipping down and preventing the gun from going fully into battery?

Mine did that for like the 1st hundred rounds off and on but hasn’t done it in the last 200 or so.  Mine is like a Gen 1.5  it has the beveled edge on the bottom of the plate which is supposed to prevent the issue.  Like I said mine did it for awhile but has been good since.    Not sure how much I trust it to carry though with the thought it could get stuck oob in a shtf moment

The failure I had with my early 1st gen P10C was initially the striker housing rotating enough to let the striker catch on the ejector and fail to go back into battery.  That happened a couple of times and finally the slide plate dropped causing a separate failure.  All of this happened within 10 rounds, so it went to the mothership for repair.

I really do believe now that the lighter striker spring contributed to the issue.  I wish I had the forethought to restore the stock striker spring and see if the issue persisted.  I’d bet a buck that it would not have since the whole initial method of locating the plate and preventing rotation depends on the striker assembly pressure which is provided by the striker spring.

The CGW fix is a simple yet elegant way of solving both potential issues.

You P10C and your concerns are perfect candidate for the CGW ‘fix’. It’s basically a 1mm dia pin which is a little longer than the stock pin on your striker assembly and a striker plate with a corresponding hole for the pin. When assembled, the pin secures the striker assembly to the rear plate and prevents any rotation of the striker assembly, which in turn keeps the striker plate from dropping down. I was one of the early beta testers and the parts have been in my gun for several months and a couple thousand rounds fired.

Sounds good, I’ll investigate the CGW solution but sounds like not available yet?


Would this be something that CZ could address as well?  Or should I say is it something that CZ would even fix?

I am one of the beta testers for the new CGW part on my 2nd P10C.  The first had already gone back to CZ for the update to the new style striker housing.  I’m at about the 800 round mark with the CGW fix on the newer P10C with zero issues observed.  I kind of like the CGW fix more than the CZ fix.  In fact, before the CGW fix was announced, I was thinking that I’d be reluctant to buy a Gen 1 P10C, but now that I see that there’s a more positive anti-rotation fix coming, I would not hesitate to buy a used P10C at all.

I’m actually at a LGS now and looked at a couple of P10c’s



This one has the notch on the backplate.  Am I to understand that these ones have the updated striker assembly?   I noticed that the backplate was in there firmly and the bottom edges do not have the beveled edge like mine does.  I’m wondering how you def can tell it has the newer components?

Did they go back to the squared off bottoms?


Is the CGW fix a fairly simple DYI?

Probably 99% of original P-10C's are not having issues with the striker rotating. I'd just shoot it.

Yes, notch = updated. The CGW fix is simple to install, takes maybe 10min at most. I'm sure the percentage of early P10's that have the striker rotation issue is small, but for $22 and 10min it's worth it for peace of mind(especially for EDC).

Ok sounds good.   From what I understand the striker upgrade checks from CGW is not available yet?

It was added to the website today. There's a link on the CGW subforum.
