Cz75d PCR

[Jet]

Haven?t really shot a handgun in a decade and decided to do a match last weekend? so total noob stuff happening. Had two failure to feed moments and am deciding to either chase it down or go buy a Glock cause I?d be interested in doing this more, but also don?t care for failure to feeds in my nightstand gun. Hoping to get some eyes on this to see if I can get help pin pointing what needs replacing or service. I?ve polished the feed ramp a decade ago when I would shoot handguns more. I imagine feeding dirty magazines probably doesn?t help much but my expectation should be that it would eat up the ammo.

10:25 - having trouble figuring this one out but to me, looks like it?s the 7th or 8th round in the magazine. I thought I ran out and reached for a mag but don?t seem to reload as I reload shortly after two shots. I have no sense of round count

16:28 - failure to feed on a new mag

What ammo are you feeding it?

[EsotericEpsilon]

When was the last time you took your cz apart and cleaned it?

The only time I've had problems with mine was after about 1200 rounds of no cleaning and the last 700 rounds on it were NATO spec with case sealer and primer pocket sealer. The primer pocket sealer was leaving specks of lacquer sealer inside the slide causing it to drag.

As L4D asked, what ammo are you using?
Also, when loading are you using the slide release, sailing the slide, or letting it slingshot?

This was CCW blazer and some old stuff in the box

I do a field clean (slide, barrel, recoil spring) and lube after each use but haven?t ever taken the whole shebang apart including firing pin out and all of that. When loading (16:27) that was slide release. The earlier 10:25 FTF was mid magazine

Field clean should be alright.

I haven't had issued with slide release myself but that could be a possibility.

Try switching ammo and see if it helps. I've had bad batches before where the case mouth was hanging up when loading. This would cause failure to load and sometimes FTE at random intervals.

Just throwing ideas out.

My vote is magazine spring needs to be changed

[AtomicOrange]

Years ago I had a CZ75 that started to randomly fail to feed after about 600 rounds through it. After researching on Web forums a bit, it seemed it might have been "undersprung" from the factory. Changed to a slightly heavier/stiffer recoil spring and that solved the problem. Also, limp-wristing could be a problem --I did not watch the video ...

[Jet]

I believe I did change the recoil spring years ago, likely to try to solve this same issue. Never really bothered me much cause I thought it was due to shooting JHPs, or dirty ammo, or whatever. But man do I have the bug for something that can shoot anything dirty.

Limp wrist would cause fail to eject and not feed, right?

Disassemble and clean your mags, dropping them in the dirt during USPSA matches necessitates that each time. Number your mags, sometimes you just have one particular mag that sucks, but it will be frustrating if you can't identify which one it is.

Run the same ammo, not some random mix of whatever you have left over, this will help isolate the conditions that cause the malfunction.

Diagnosing a jam is hard under match conditions, you are distracted and working under time pressure, you don't take the time to really size up the specific jam characteristics.

As above, one important part is to clean the magazine. Take it apart, and pull a hand towel through it a couple of times, check for left over grit. Then wipe off the spring and follower and reassemble.
If you get dirt in there on a double stack, it can wedge just enough to be a problem.
Limp wrist can also cause problems.
Maybe recoil spring, but I'd ask another (known good) shooter to test it with known good factory ammunition. CCI blazer has always been good for me. Keep track of the problems with which fodder.
CZ's have always been flawless for me with decent ammunition, assuming cleaned once in a while and oiled a few drops once per range trip.
good luck!

Can cause either fte or ftf, especially with too much spring. I just went up a pound or two on mine. @eaglemike's idea to have someone else shoot it and try to replicate the problem is a good one, before changing parts...

Most failure to feeds usually come from either the ammo or the magazine. With a fully loaded magazine, take your thumb and rapidly push each round forward out of the magazine and let them fall on the ground, best to do it over carpet; see if any of them catch on the front lip of the magazine body or require force. If any of them do then it could be a weak magazine spring, a worn out follower, dirty internals or the ears of the magazine are no longer in spec causing the round to exit the magazine at the wrong angle. This leads to nose dives on the feed ramp.
Dont grind down the feed ramp whatever you do. Also, try different magazines and different ammo and see if things change. MecGar makes the magazines for the newer CZ guns so just pick up one of their branded mags at your LGS. They are cheap and a different brand of ammo should give you some answers.

CZ has some pretty wide tolerances, some guns run great out of the box, others can't get through 10 rounds. There is a good knowledgebase out there from people who started using the sp01 in competitions 10-15 years ago. Many of the minor break-in issues for the sp01 are exacerbated in the mid sized and compact guns.

Some folks just put in heavier springs and run them wet for a few thousand rounds. I'll pull the grips off any new cz and cycle it a bunch in a tupperware of mineral oil until the oil comes away clear.

But I'd recommend reading some of tge threads on fpb CZ's over at Brian Enos' forum or on the Original CZ forum. Here are a couple good reads, again on the SP01, but same principals apply. CZ's are solid guns, they should not be ammo finicky or affected by limp wristing. If they are, they probably are not broken in yet.

Hope you get it worked out.

I’m gonna rule out break in. Owned this gun for 20 years and shot from stationary a bunch, with maybe a ftf or FTE every other time at the range. Never thought much of it until there was a clock involved
