Title: P10C striker question
Post by: Boriqua on November 30, 2019, 11:04:50 AM
Guys I am so sorry if this has been answered a dozen times but I did a search and I may be to block headed to find the answer.

I have been out to the range 3 more times with my P10c and will reiterate. It is my favorite plastic 9mm EVER. Just a juicy trigger and I can put hole in hole. Its fast, it points naturally and I love shooting it.

I have been paying attention to all the striker rotation concerns and understand that the issue was addressed by CZ in later iterations..

How can I tell if mine is one of the guns with the updated arrangement? I love the gun so if its something I should take care of its fine. I just bought it about 6 months ago on special and it is the model with the ambi safety.  Can I tell from the Serial or ??

Thank you everyone .. and again .. sorry if I just missed the answer!!
Alex

My slide is out for milling or else I'd post a picture, but there should be a small square notch cut out on the back next to the cover plate at around the 3 o'clock position.

So, since I am brand new to 1. this forum and 2. CZ pistols, help me understand your reply to the OP...strikers were rotating apparently, and this was discovered and fixed by CZ...and the little notch you posted signifies a later model with the mod to correct the rotation?...am I correct?
Thanks for your reply

Can someone point me to this striker issue when back plate does not have notch? I bought mine soon after release, no notch.  Shoot some IDPA with it.  Have around 800ish rounds through it.  I like how it points but dot sights are too big which is why it is not main carry.
If this is a CZ problem will they warranty fix?

As far as I'm aware it was a rolling design change not a "defect".  There are companies that can do the retrofit for you if you have an older P10C.  Primary Machine is one, I think there are others as well.

In my opinion it is a non issue.  I was an early adopter of the P10C.  No one heard of this issue until someone posted a YouTube video of their fully cerakoted pistol that would hang up.  Then others posted videos where the user was reaching under the slide and manipulating the striker to get the slide to catch.  Those of us that just loaded the mags and shot our pistols did not have an issue.  Even the owner of this forum posted a video showing how the striker was not an issue. 

CZ did a product update to fully negate the ability to manipulate the striker to hang the slide up.  I would think if you have an issue with your pistol CZ would warranty if but if you only want a piece of mind fix you probably just have to pay Primary machine to mill in the grove.  David

CGW has a kit to fix the issue.    https://cajungunworks.com/product/p-10-c-striker-anti-rotation-kit/

Here's a good YouTube video pertaining to the striker rotation "problem":  https://www.youtube.com/watch?v=Xix0X2GiHAA

I've got one of the first run p-10's and never had a problem with striker rotation, or any problems at all.  I will however be sending my slide out to PM for the "fix".  I have close to 20,000 rounds through it and I've been replacing worn parts as needed. I recently ordered and received a new striker assembly from CZ and it has the newer tab which isn't compatible with my slide as it is now. So for ease of maintenance now and in the future I decided to get the notch cut.

I had an early one.  While I didn't have the striker rotation problem, occasionally the slidecover would slip down and catch on the frame rails.

On the right, you can see the plate has slipped down.  CZ's fix was to bevel the slide cover so it wouldn't catch.

The reason CZ added the square notch wasn't necessarily to prevent the hangup issue.  If the striker assembly drops down a bit, the trigger pull essentially gets longer since you have to pull it a greater distance to drop the trigger bar clear of the striker.  Some people had issues where the striker wouldn't release with the trigger fully to the rear.  By limiting the downward movement of the striker housing, you get a more consistent break.  Similar in effect to dry-firing with without a magazine installed.  It makes a bigger difference than you think.  When I was doing trigger tests, I mapped the difference between a loaded mag pushing the slide to it's highest position on the rails, vs no mag and the slide free to drop down.
