P10C NOT LOCKING BACK AFTER LAST ROUND (NOT A GRIP ISSUE)

[clbelinoski10]

My P10C has about 2000 rounds through it. As of lately, after the last round it won't lock back. I tried it again only loading half a magazine worth and it still won't lock back.  I've tried both the OEM magazines as well as another OEM mag with the shield arms 4+ mag extension and i get the same results.

That being said I cleaned the gun and removed the slide from the frame to make sure the slide stop was engaging when an empty magazine was inserted and its seems to being engaging just fine.

I know there is a few other post referring to a high grip and made that adjustment very earlier on after purchasing the pistol. So I know 110% it's not my grip in way kind of way.

Since I've noticed the issue I've tried 3-4 different brands of fmj ammo (all brass casings) to ensure it wasn't the ammo. Still no improvement.....


at this point have no idea what it could be, my next guess would be potentially something with the recoil spring? Before going back to CZ, if anyone has idea what the hell is happening I'd greatly appreciate any advice....I love the gun and not knowing a solution is killing me....

Call CZ USA and explain the issue. Let them fix it under warranty.

You say you know 110% that is isn't grip related. But. . .have you tested it shooting strong/weak hand only?

[jurek]

Even you already took the handgun down, remove the slide release and spring. Compare your spring with original one if the shape is the same.

That's a well meant advice.
But how shall he do this? He has only that spring, he removed from his gun following your advice.

Yes, you are right, that such comparison won't be perfect, but at least you can have any idea if it does have any imperfections.
Look at CGW website, they have pretty good pictures (can be zoom in), or YouTube videos where people show how to replace it.
Sometimes it can be broken or bent "J" tip, sometimes this spring sits incorrectly on the slide release's groove.

Maybe you don't know it,  I am from Germany.
Therefore many of the abbreviations used by Americans on gun forums were or are still unknown for me.
CGW is such a still unknown example.
Can you enlighten an ignorant German what that means? 
If you write that there are many pictures of CZ pistols, also to be enlarged, I can also use this website in the event of a future problem with my P07.

Actually I know that you are from Germany... I've been reading your few posts recently...
The reason I used "american" talk was that all these were written to clbelinoski10, who hopefully understood it...
Do not hesitate to ask questions if you do not know something... this Forum is to share the knowledge (ok.. I know, I know.. you don't have good experience with recent discussions...)
CGW - Cajun Gun Works (https://cajungunworks.com/)
CZC - CZ Custom (https://czcustom.com/)
These two names are mostly found here - both are Companies making aftermarket parts for CZ firearms and also personalize them for certain purposes.
Regarding CZ pictures.
In this particular case I pointed to slide release spring. When there is nothing I can compare to, I always look for it in the Internet. Google is my friend. At least I have an idea how the part should looks.

These: "Sometimes it can be broken or bent "J" tip" were only my words used to describe the oval part of the spring...

I cant think of what will cause the issues you are having. 

My personal opinion, is that the grip should NOT be an issue since you are not having issues with the other x many rounds and the other mag.  I took a friend out shooting and when he was shooing my HK  P30L, it was doing random failure to ejects.  I was just shooting it and did not have any issues and that was the way before i had shot it too.  but what happen was that he was "limp wristing" the gun.  After i showed him what he was doing, it cleared up.  But from time to time, he would do it again.  I think it was sort of him being "out of shape" since if you have not shot guns you may not have the hand/wrist/arm strength.  But again, i feel your grip is not the issue.  I could be wrong, but your solution will tell.

But im thinking that its maybe your mag.  It maybe dragging on the bottom of your slide?   

If you want, maybe fill up a mag with a few rounds and when you are shooing, use your free hand to pull down on the mag base for each round.  Not to "remove" the mag, but if there is any "extra?" friction/rubbing on the bottom of the slide, it maybe enough to allow the slide to move all the way back and lock back.

Also, someone posted some failure to eject? movies using a cellphone camera in slow motion.  If you have a camera with this feature and if you can get someone to take a movie of it, it may disclose the issues.

But to me, in order for the slide release to engage, the slide MUST travel rearward far enough for this to happen.  Again, not sure if it is happening or not.  Then you need the follower to push up on the slide release.

and you may want to make sure the slide release is free/loose to move if it needs to with the mag not in place.  see if you can push up on the inside tab as an empty mag would.  Maybe use a pencil and the eraser end to push up and see if it moves freely.

good luck and come back on what you find out.

He said he was having the issue with multiple mags and a variety of ammo. . .

[eastman]

disassemble the mags and give the insides a good cleaning. Check the witness holes for burrs. I like to slick up the insides with Meguair's auto polish.

I have needed to clean a P-10c mag because it wouldn't always lock back on empty.

You quoted yourself and highlighted in red. . .ok,  I must be missing something. He said he had the same problem with multiple mags and different ammo. You're saying he didn't?

OK. I see where i fubared.    I didn't mean to have the "not" in there.  I was fully aware of the different ammo and both? mags had the issue.

but i still stand with doing some testing.  to me, its not rocket science and he has all of the stuff to do it. 

do the easy stuff first and work you way into the rabbit hole.
