CZ P10C Striker Rotation and out of battery fix.

[Jreeves]

Too all the Beta testers, the parts will be back from coating in a couple days, I tried to test a raw sample and it received scratches, without having a coating, not anywhere that mattered but in 1 cosmetic area.
These prototypes were made to dimension for no coating to be applied, but a minimal coating needs to be there, so I am having a minimal Type II Anodize added, which is very thin but will allow for testing.
I will send these out to those who asked to be signed up for testing as soon as I get them back, Thank You.

I have also received Delrin stock and will machine the same part from Delrin and send those out to you as well, as soon as I get them done.

Are you still accepting beta testers? I'd be interested in the Delrin when it's available.

PM me your shipping/contact information, I have not made the Delrin parts yet, been super busy, people ordering sights like CRAZY.

[Jreeves]

To all on the Beta list, parts are in I will try to send them out Early next week, been super busy, I manufacturer all the sights for a sight company, people ordering them like crazy I guess, mostly police and military.

There is a tight spot on the part, where the cylinder inserts into the slide, this will be reduced in production, and also a thicker more durable surface treatment applied if all goes well.

Mine was tight enough that it got stuck first 3 shots, but then was fine after that, so should be fine on reduced production models.

This is considered a metal to metal interface so minor lube should be used, Delrin parts will not need lube.

And my drop safety worked every time, and I cannot get it to fail manually like the plastic part, that fails even in the newest model P10.

Thank Guys, CHEERS!

Hello.
New member here. I watched your video with great interest. I am not an engineer but your video and the accompanying explanation make  a lot of sense and much clearer than some others on youtube. I have held off getting the P10 simply because of the this problem and I am hoping that somebody can come up with a fix. Looks like your device may be the solution. I understand that the number of cases reported have been very small, although the actual number may be higher and some do not show up until after several hundred or thousands of rounds. I just have one nagging concern in the back of my mind:
How can one be certain that this device would work, considering the small random number of reported cases. This is because:
1. The number of rounds fired may be too low to trigger the malfunction;
2. The weapons used by the Beta testers may not malfunction at all, so one cannot tell if the normal functioning is a result of the new device or not.
I understand that there may not be an answer to this question, but I just have to voice my own concern.
Regardless, your demonstration is very convincing and I definitely would get one when it is in production because this pistol has a very good trigger and a trigger reach to boost. Thanks for the good work

Any further updates on this & the beta tests?

Interesting...

FYI - If you have the newer model with the extra channel in the slide by the striker, this mod/fix isn?t needed.

I hope so.

So the newest CZ P10(2019 Editions) are made differently? When you say this mod/fix isn't needed, can you explain why?

The 2018+ models have an extra channel machined by the striker that locks the assembly in place and keeps it from rotating. The assembly itself on those models has a notch that rides in that new channel which does the work.

The part detailed in the OP?s video actually doesn?t have the notch that rides in the channel, but the fitment is so good that it doesn?t rotate. CZ probably should have just machined it out of aluminum to the specs the OP did in the first place and they wouldn?t have had to come out with the fix they did.

Either solution is effective, and I would probably buy an aluminum part that HAD the notch if the OP produced one, just because the tolerances and fitment on it is really nice. As it stands, without the notch, I?m going to keep CZ?s stock fix in place.

Hopefully the OP chimes back in, do you know IF the CZ P10F uses the same size as a P10c?

Unfortunately I don't know if the design is the same on the F. If I was a betting man I would say it probably is, but that's just a hunch.

[armoredman]

Since the S is the same, I'd be very surprised if it was different.

Hello, I have made a after market part to replace the polymer striker carrier housing on the P10C anyone interested.
Need to have it Beta tested.

Very informative and interesting video and solution.
I would be interested and left you a message.
Thank you for your efforts
