Have you tried other hollow points? I've heard of that ammunition causing problems in other guns as well

 

I saw your other post as well.

First off, are you riding the slide forward when trying to load these rounds? Or are you using force when racking the slide?

Have you shot the gun?

Take it to the range and put some rounds through it. See how the gun really functions, not when you’re manipulating it by hand.

 

I recently got the CZ P10c and f full size, so far they have run everything i've fed them, hollow points and FMJ's including Sig V-Crown 115 grain, haven't tried the 124 grain though.

 

Shoot 100-200 rounds of fmj through it to calm your new gun jitters, get aquainted, then try the hollow points after that. It's called breaking in the new gun, but really is breaking in the new owner.

 

I wouldn’t trust my life to any gun that I can’t get to run reliably. If your gun runs FMJ reliably then try different hollow point ammo, such as Federal HST. I wouldn’t sell a gun because it didn’t like one particular brand of hollow point ammo. I don’t carry or shoot Sig V-Crown, so that wouldn’t concern me. if my gun couldn’t run reliably with several brands of carry ammo, I’d contact the manufacturer and have them sort it.

 

My P6 will not feed those reliably either. Just don't use them. It is not possible for every gun to work the same with every type of ammunition. That's why you find the ones that work best and not try to force the unreliable to work. It's something everyone experiences whether it's a .22 or a 10mm. Guns are different.

 

It's a CZ, thus it hates made by Sig rounds

 

If it wouldn't run Speer 124 gr Gold Dots I'd get rid of it. Don't know anything about the V-Crown rounds.

 

CZ's are not chambered to SAAMI specs. Any case length (not OAL) over .750" will give you problems. It's a well known issue with CZ.

 

I would:

1) Test with different magazines to see if it's just a bad magazine

2) Test with different JHP ammo

3) Contact CZ USA

It's true that CZ cuts their 9mm chambers a little short but if the rounds are getting stuck on the feed ramp that doesn't sound like a chamber problem.

 

Boutique rounds shouldn’t be used to judge a firearm.

 

IDK...my P10c fed everything...I think the op got some good advice ..too soon to give up on it yet.. work the problem, then decide

 

I've had issues with Sig V-Crown 124 gr JHP in a few different guns, including my Glock 43 with both its OEM mags and my custom modified mags. Their wide mouth HP seems to catch several guns on the feed ramp.

HOWEVER. As it's been stated, my P-10C also runs everything I have thrown at it (not V-Crown, because I don't buy it anymore ever), so Just run a couple hundred rounds through it and break 'er in!

 

All my P10’s eat everything 100% reliably. They are some of my best shooting pistols. If it’s a problem I’m sure it’s because it’s made by Sig. Anything other then their metal framed hammer fired pistols are suspect to me and I own quite a few lol.

 

Posts #2, 3 & 5 cover some of the usual basic trouble-shooting.

Also, as is often stated in a number of different gun company armorer manuals I've received over the years (and was heard in the classes I attended) ... if one brand of ammunition is being used when a functioning problem occurs, try another brand.

If it were me, I'd try something from one (or more) of the major American ammo brands before I started to suspect it was a 'gun' problem.

Sure, it might be a problem with a chamber spec, but when you mention the JHP nose is getting caught against the feed ramp, that would mean the cartridge hasn't even reached the chamber. Is that right?

So, maybe back to trying some different, major-maker JHP's.

That's where I'd start, if it were me, or one of our people who brought me a new gun and reported the same problem when using some small brand of ammo they'd bought on their own (and weren't using any of the major-maker duty/training ammo we kept in-stock).

 

FWIW....try a heavier bullet like 147 gr. HST's......? My Glock 21 doesn't like semi wadcutters.
sometimes they feed but mostly don't....! I just shoot bullets with different ogives. Hope this helps a little! lol

 

OP, this presumes your new CZ is being used in normal, good condition.

One of our guys bought one of the CZ P-01's when they were the hot thing several years ago. While he was using it on our older outdoor (sand-covered) range, he dropped a loaded magazine in the damp sand. Unfortunately, it happened in the middle of a qual course-of-fire, and he picked it up, shook it and inserted it into the P-01. He got off 1 round before the slide seized during cycling, and was only partially closed. The gun couldn't be cleared or manipulated in any manner. It was solidly locked up and inoperative. Since none of us were certified as LE armorers for CZ, and we didn't want to risk affecting any warranty, we didn't attempt more than normal action correction methods. The head armorer told the owner to take his gun to a gunsmith authorized by CZ. A little bit of sand ...

 

Thanks to everyone who took the time to answer my question. I called CZ and was told the gun was manufactured to European CIP standards and after shooting a few hundred rounds through it the barrel / feeding chamber should widen and be able to take hollow points. I decided to keep the gun but also buy a Gen4 Glock 19. It’s the newest version that still has the finger grooves and will chamber anything you Fred it.
wishing all of you the best

So, the steel of the barrel's chamber and barrel leade is soft enough that it will 'widen' by having a few hundred cartridges pushed into it? Never heard that said by any of the gun makers whose armorer classes I've attended over the years, including those from EU countries. EU CIP standards?

I'd try some different JHP's, if it were me. If the problem immediately disappears when using any of the major American makers of JHP ammo, but continues to happen with the brand you're using? Well, that might be a hint?

I'd not discount the possibility of the brand of ammo you're using to be producing some lower power, which is short-stroking the slide's travel, which can affect reliable feeding (i.e. the "timing" of the salide picking up and stripping the rounds from between the mag lips).

 

hello,
I just called Ghost Products CZ Custom Shop in Mesa, AZ, to get another expert opinion. I was told that to try 115 grain hollow points with a less rounded tip that the Sig hollow points, I want to try hollow points with a more of a slope. And I was told that after few hundred rounds of full metal jackets are fired, the feeding chamber will become more polished. Does this seem logical to you guys?
Thanks

 

That’s basically a break in period. I’d suggest trying that and if it still has issues send it back to CZ to get fixed.

 

Why not try their suggestion, if they're speaking as an experienced CZ custom (3rd party) shop who has some hands-on experience with the products? This might fall back to the way armorers have long been told by some gun makers that if one brand/type of JHP doesn't feed and function well, to try another brand.

 

Yeah, this is exactly why I went back to older school rounder JHP rounds. A lot of the newer boutique ammo, or Hyper Ammo as Paul Harrell calls it, is just a bit more picky. He has shown in test after test that, yes, the newer JHP rounds do expand and perform marginally better; this difference and money one is willing to spend for that difference is up to the individual.

The two JHP rounds I purchased and use are WWB 115 gr JHP (I know, I know, it's the only WWB product I have any faith in) and PMC 115 gr JHP. This is one reason I prefer barrel lengths over 3.4-3.5" with few exceptions. When utilizing older or more conventional JHP projectile design rounds, velocity is everything. Going from 3.4" on the Glock 43 to the 3.1" on a Shield Plus can mean staying above or falling below the 1000 FPS mark, and once you fall below that, you begin getting dangerously close to expansion threshold on many of these JHP rounds. That small difference may seem inconsequential to many or make me seem like I'm too velocity focused, but both of those rounds still do relatively well, if they have the velocity behind them. I'm done spending north of a $1 a round. I can get boxes of 50 for $20-30.

To each their own. Point of my long rambly post was to try new JHP ammo. Several of us have stated V-Crown is temperamental to say the least. Additionally, it's why I also just went back to older projectile designs that are not as wide an opening and more rounded. They feed a lot more reliably.

 

... Additionally, it's why I also just went back to older projectile designs that are not as wide an opening and more rounded. They feed a lot more reliably.

When gun makers were still designing their feed ramps for Ball, the ammo designers tried to make their older style JHP's as Ball-like as possible in profile, which also meant trying to keep the OAL close to Ball dimensions. (The 147gr JHP's could give some pistols designed with older barrels and feed ramps indigestion, for example.)

When that did the trick with some of the barrel feed ramps which weren't originally designed with JHP's in mind, then the older style JHP's did seem to be more velocity-dependent to for expansion to occur.

You'd think that since we're long past the 70's & 80's, that all the gun makers would be designing their pistols to be comfortable with the modern generation of JHP profiles. Shape-wise, anyway, since there's still the 'power' thresholds to consider when it comes to tweaking recoil springs/RSA's to accommodate the slide velocities needed for optimal feeding timing and functioning. This is where we've sometimes seen a little bit of a disconnect between European and American gun & ammo makers.

Once you find what runs well within your favorite pistols, there you go. If your favorite brand of pistols are more tolerant of the efforts of different ammo maker products, good for you.

One of the things that has seemed to have driven the gun makers to devote more attention to being tolerant of American JHP ammo is when some of the big name gun makers are doing a lot of LE/Gov contract business, when they're told what sort of JHP ammo their customers are going to use. Market demand drives the design revisions.

I suspect that this may not have been a market where CZ has prioritized their efforts in the US in the past. Perhaps now they may become more interested, especially since they've acquired Colt and have a CZ-USA LE/MIL division.

I remember when the CZ-75 was just released, but it was a unicorn here in the US. Even Cooper talked about it. Naturally, the roots of the design was built around Ball back then.

 

Not all ammo works with all guns. That's reality....it doesn't matter what you want, or accept or reject, it is what it is.

If you find a "gun" that shoot's all ammo, Marry it.

 

I remember when one of the gun companies submitting exemplars for testing for new duty weapons asked me what duty ammo we intended to use, if we selected their weapons. When I asked why they asked and why it would matter, I was told that their engineers were constantly receiving and testing the major American JHP ammo being bought by LE. That being the case, they might have acquired some feed back regarding their experience in how our choice might've done in their in-house testing.

I was also told that they repeated their in-house review of current ammo, since the ammo makers were either always revising their products, or their testing of some production lot(s) might reveal a QDC issue, which could then be checked when they received the next production lot(s) of the same brand of ammo.

My impression was that this was something they quietly offered their potential, and existing, LE/Gov customers.

Just one of those interesting things that make you go ... hmmm.

 

Hello,
A quick update. I spoke with CZ USA again and they told me to send the gun in and they'll put a "Throat Extension on the Chamber". Hopefully all will be well after that. I agree with RWBlue about why he loves Glocks. I'll carry my Glock 19 as for CCW. I'll use the CZ as a range gun.

This makes it rather seem that they have an alternative response for customers reporting this issue ... if they aren't satisfied with the first answer you were given.

FWIW, something similar was discussed on the Brian Enos forum back in 2010 regarding having to throat some CZ barrels to correct a short barrel leade issue. Custom chamber reamer.

Throating a CZ barrel

I would like to shoot longer rounds in my Shadow, but am restricted by the barrel. I use Bear Creek 130's and if loaded long it gets caught in the rifling. Has anyone here throated the barrel for longer rounds? Did it affect accuracy at all? Function ok? thanks

forums.brianenos.com

Many years ago I was shown by the then-head armorer (who was also a machinist) how to use a chamber reamer to resolve an occasional short leade issue, and any high spots in the chamber, of some older S&W 3rd gen pistols. It cleaned up both any high spots in any particular 'sticky' chamber, and cleaned up an occasional uneven barrel leade. I inherited some of his tools, including those reamers, when he passed. I never bought my own because I always had access to his, even after he retired (but still lived nearby).

You'd think (hope) that some newer generations of ISO machining capability would've taken care of such things, but then there may still be some differences in specs in some things between EU and American gun makers?

Let us know how it goes.

 

Fastbolt, thanks for taking the time to respond and I appreciate the link.
