P-10c Ejector

I've been trying to find anything common between your cases...
Has anyone checked (whoever got bent ejector) if your magazine does touch the ejector? Perhaps this bend is caused when you smack magazine too hard?

I do think it has to be related to use; like I said, mine used to auto-forward, now it won't.  While I was speaking with CZ on another matter this week I mentioned my ejector and they offered to send a new one, which they did (thanks, CZ!).  Here's a closeup of the new one:



I'd call it . . . wavy, not bent.  Maybe having the ejector perfectly straight is not necessary for function (except possibly for the auto-forward action which I don't believe was ever called out by CZ as a feature).  The old and new part look identical other than the mold numbers on it.  I can get a pic of the magazine/ejector interface when I reassemble things, but Earlan357 mentioned the top round does contact it.

Here is a photo of the mag inserted, I tried both the original 15 round and also with the extended baseplate, neither came close to contacting the ejector, even when I pushed up on it:



What does contact the ejector is the top round, and I guess a full mag would make a solid impact, especially given a good whack.



The design of the ejector is fine, as long as it doesn't get hit from the side, but that's what is happening to it (from the bottom) when you ram a fresh mag in.  Actually, it continues to work after it has bent up, the only difference I've noticed is my auto-forward seemed to no longer be there, and that wasn't an advertised feature.  So maybe this should be considered a non-issue?
  Now that I've replaced the part, I'm going to treat it nicer and see if it treats me nicer!

Any updates?  I'm curious to hear what CZ had to say, if anything.

I received my new ejector from CZ a while back and it is straight.  I'm going to modify the new ejector so it no longer makes contact like @earlan357 did.  I want to be able to count on this pistol but this issue has to be addressed even if there are few reported breaks.

This seems like a good opportunity for a company like Cajun Gun Works to offer a reliability solution.

I swapped out my bent searblock/ejector.  I'm not thrilled that CZ engineered the ejector as part of the sear block but it is what it is.  The old ejector made contact with the top round in the mag when seated aggressively which most likely why it bent.   I checked this by seating the mag until the base plate was in contact with the grip frame.  I then attempted to insert feeler gauges between the round and the ejector.  No gauges fit between the top round and the ejector and I could see a slight movement of the top round when pressing the mag fully in.

Today I replaced the sear block/ejector with a new part that I ordered from CZ last month.  All markings on the two parts are identicle.  The part was relatively simple to swap.

The new ejector makes no contact with the top round when the mag base plate is fully flush with the grip frame.  It does have a very slight bend that seems to be molded into the part but it is not as aggressively bent as the old part. Obviously there are some manufacturing tolerances at work here.  I was able to fit a 0.0015 feeler gauge between the top round and the ejector.  It's not much but there is no way to get the mag in any further so with this mag at least I am good to go.  I'll check it with some other mags to see if additional mag  tolerances come into play.

Below is the old bent ejector.  Notice some very slight finish wear at the bottom edge.  This is where the contact takes place.  It looks like it would be very easy to relieve this spot with a stone to add clearance if necessary.  You can't see in this pic but the profile of the face is radiused to fit around the top casing in the mag.

I relieve the underside of the ejector and now have 0.010" clearance.

Well after 200 rounds theres a lot of brass on the bottom of the ejector.  Hopefully not enough contact to bend it.

Mine is a 2018 Czech version. The ejector (#5, insert, rear) was slightly bent from the factory.  Has been working perfectly for the first 200 rounds, with automatic forward.

It seems to me the slightly upward or the ejector is what causes the auto-forward.  As seen here in the photo, when the magazine with bullet(s) is loaded, it bumped the ejector.  Then the ejector bumped the slide, causing the slide to move slightly upward, hence disengage from the slide stop (#6) and move forward.

If the ejector (#5) is completely flat, I imagine it will take more force to insert the magazine, in order for the pistol to perform the action.  I suppose we wouldn't need to worry much about breaking the ejector (#5), as it wouldn't bend any further after hitting the slide by design.  Only when it's being flatten purposely (unfortunately probably also unnecessarily), can the stress causes it to break off.

As usual, any opinion or corrections are welcomed.
let me try to upload some photos when I figure the logistics out...

My Gen 1 P10 c has a flat ejector and has performed  flawlessly for over 25000 rounds. New purchase Czech  made with curved ejector  not so much. Time will tell.

Today I went to the range for the second time with my new CZ P10c. The gun has around 350 rounds shot total. It worked and is still working perfectly fine with the exception of 4 stovepipes during the last 50 rounds or so that I shot today at the range. When I got home I field stripped the gun to clean it and I found that the ejector is broken clean off. (sorry for the pic quality, phone camera sux).







The bullet rides way too high with mag fully inserted and so does the slide stop bar in my opinion.

I never noticed when it broke and have no idea what happened to it. Gun continued working as usual. I always thought that part looked bent but I thought it was normal since gun was working fine. This is a big flaw, big one, and apparently not uncommon.

Wow not good, before it broke did you do anything to the ejector like bending it back to straighten it or anything at all? Also not that it should matter but do you slam your magazine hard to seat it home?

How long has this been an issue or how long has owners been reporting on it, I'm guessing this includes all the P10C models like the newer OR version?

Whatever the answers it appears this is indeed a real issue and probably deserves a recall, don't you think so?

Great information everyone and thanks to all for contributing!

I just picked up a 2020 CZ P-10C through an internet site and have a few issues out of the box.   I do have what seems to be a bent or warped Ejector (#5 Rear Insert) with metal wear.  The finish has been scraped off from what seems to be interference with the #17 Slide Cover during assembly/disassembly.  The #17 Slide Cover also has some displaced material from that interference.

Anyone else's slide cover look like mine from the left/right play in the slide to rail fitment?  I'll be reaching out to CZ soon.

I have not fired this P-10C, nor loaded anything but a single snap cap.

Your last picture caught my eye because mine looks exactly the same.  I had thought my rear block was somehow sitting a little off axis.  I checked it as best as I could with a straight edge and the front and rear rails all seem to line up fine.  It is a weird quirk of these pistols that I have seen on others.  It doesn't seem to effect function or accuracy but it does look a little low rent.

I spoke to CZ-USA and they are sending me out replacements for #5 and #17. Great customer service!

I have a brand new P-10 S, never fired. I have been waiting for some sights and a base plate for a RMRCC. I’ve manually manipulated the slide and trigger to smooth things out.
My ejector is shiny metal on the top surface because it is rubbing against the slide, the ejector has a substantial upward bend.
