Failure to feed

[Strongcoffeee]

Hello
I bought a CZp10c 2 years ago new and I love the pistol.  The last time I went to the range I had multiple failure to feed problems with the gun.  I am using the same ammo I have used for years freedom munitions 124 FMJ.  The only thing that is different is I had installed a Cajun Gun works trigger and I do not believe that is the problem.  Someone asked if it was my mag.  Well I had several mags and while I am not sure I do believe that it was happening with ore than one mag.  It must have failed over 20 times that day.  Any thoughts on the problem?

I'm not being a smart ass, however when was the last time you cleaned it and the mags?

Can you describe the failures?  Rounds nose diving under the feed ramp? Rounds enter the chamber but don’t fully seat?

Do you have access to a chronograph? Be a good idea to check the speed of the ammo.

We need to clarify few things to find solution:
1. "I have used for years freedom munitions 124 FMJ"
- is it branded ammo or reloaded? When I've checked their website I couldn't find brand "freedom munitions 124 FMJ" 
2. When have you cleaned and lubeed the gun and mags before you started shooting again?
3. "I am not sure I do believe that it was happening with ore than one mag"
- you have to specify if it happens with one particular mag, or with all of them
4. "I had installed a Cajun Gun works trigger"
- if we don't know the answers for 1, 2, 3.. we won't find out if 4 might be a reason.
Anyway... CGW parts are not "Holly Grall" - I've used multiple CGW parts and sometimes found that factory worked better, or even CGW haven't fit the pistol...

Give us more info, please.

Thank you so here are my responses
1.  The ammo is not reload all ammo I buy is new ammo and it is freedom munition’s own brand
2.  I clean my mags regularly (taking out the spring and cleaning the inside as well
3.  I do not believe the failure to feed is isolated to one mag but I a going back to the range this weekend to test it AND I will use a different ammo

Great ! 
1. So I would not bother ammo anymore...
2. All cleaned, so not issue here
3. Check the mags again to isolate the problem. If you find ONE mag failed, you know where is the issue
4. If you still have failure to feed, and you are 100% positive that you have the same shooting technique  I would say the issue is in one of these:
A. replaced CGW parts (if you still have factory parts, set them back on the gun)
B. weak recoil spring (I don't know how many rounds the spring already have, but "regular" spring can be bad after 5,000 rounds. Next spring change - go with flat one)
C. check if feeding ramp is smooth (should looks like mirror after you clean it)

I'd ensure that the mags are all assembled correctly as the spring can be installed backwards. If all is well I'd swap back the factory parts and see what happens. If the issue persists at that point the gun is under warranty and I'd contact CZ-USA.

Polish the feed ramp on the barrel. Also use some 1500 grit sandpaper and lightly sand the feed lips on the mag making sure there's no burrs.
Using 1500 sandpaper and a credit card put a credit card in the paper and lightly deburr the slide rails and then apply a little bit of Molly Grease to the rails. Also double-check your reassembly of the magazines. Oh also polish the bottom side of the firing pin Channel where the next round coming out of the magazine rubs when being chambered.

My two questions are did the pistol work fine before you installed the CGW parts and did the gun ever work fine after you installed the CGW parts.  Trying to isolate an issue with mags or a recoil spring is going to be difficult unless you are certain the aftermarket parts were 100 percent at some point.

Also I’ve owned 4 different P10C pistols and about a dozen other models. CZ’s are not known for needing to polish the feed ramp. David

Unfortunately my P-01 Omega needed one. I had feeding failures which were fixed by polishing the ramp.

My Urban Gray P01 Omega would get the occasional (but not allowable/acceptable) nose jammed/stuck on the feed ramp with 115 grain bullets now and then.  Kept me from carrying it there early on.  I polished that feed ramp from the factory black color (with a tiny sort of line across it I could feel, but not see) to a nice shiny mirror looking finish.  No problems since.

The black P01 Omega never had this issue  and is still stock/no polishing/mods except night sights.

That UG P01 is the only CZ (out of a bucket load I've bought) that had issues.  Front night sight died and the failure to feed issue.  Both fixed.  One my me and CZ took care of the front sight failure.  Then I went and bought the black one.

Of all the people I know of  that like to polish the internals of a pistol just to smooth out the action,  I don't believe there's anybody that doesn't polish the feed ramp. And that includes many certified gunsmiths.
If you  like to keep your guns totally stock and never take them apart and that's your thing, more power to you.

So just to be clear, I am the Armorer of a department of 600 Officers and I have been to at least a dozen armorer courses. I am not a gunsmith but do work on guns everyday at work. That said I tinker with guns as much as anyone.  If you make changes to your weapon that causes malfunctioning you must begin to methodically isolate what the issue is.  Polishing something is another alteration that may or may not help until the original cause of the malfunction is identified. I can honestly say I’ve seen more issues created by “light polishing” than anything else because everyone’s definition of light is different.  Also most people don’t start polishing things until they think they are correcting some other issue.

The OP is looking for an answer as to why his pistol is malfunctioning. In my opinion isolating changes until the cause of the malfunction is identified would be my course of action. Polishing would be another change and I would not start with that to begin isolate an issue. Good luck. David.

agreed ^^^^^^👍.
I don't polish because of an issue I polished just to smooth the action.
 and yes I learned early polishing too much can do damage.
I can't say that factory Parts aren't broken when shipped oh, that is a possibility.
I still believe his problem can be fixed by, checking the reassembly of the magazine, polishing the magazine feed lips lightly, polishing the bottom of the firing pin channel to help allow a smoother chamber of the cartridge, and smoothing out the feed ramp.
These factors are a major cause of FTF.
I understand the recoil spring has a big play in it, and there is also a slim chance the new trigger may be causing timing problems and needs to be fitted properly. Which should be done by a certified gunsmith.
