CZ 75 P-01 Hammer Pin Backing Out

[hongrn]

My CZ 75 P-01 is only a couple of months old. At the range yesterday, just after about 50 rounds, pressing the trigger didn't do anything, as the hammer stayed cocked. I removed the magazine, ejected the round from the chamber, made sure no squib was in the barrel, and upon close examination, saw that the hammer pin protruded on the left side of the gun (first pic). I took a flashlight to the other side, and saw that the hammer pin no longer lined up with the hole (pic 2), so there's no way to push it back. I manipulated the hammer to see if I could line up pin and hole, but it's a no go. I'm going to take it back to the gun store and see if the gunsmith can help. Have you seen this at all? Any quick fix? It's kind of disappointing on a new CZ for sure. Thanks in advance.

I'm assuming you have never touched this pin before? Have you noticed this pin sticking out before?

Push the hammer down to line up the pin with hole and push the pin back.
It may work or not.. but whatever result is I'd recommend to disassemble the pistol and check the hammer pin.
Is it still under warranty?  Contact CZ directly or the store you bought it from.

I just have to wonder if someone had the gun apart before. I've never seen nor heard anyone complain of that retaining pin being missing from the factory.

This is a very dirty used surplus Pre B CZ85 but the pins used are the same.

See the little vertical pin sticking down from the top of the hammer pin hole to hold the hammer pin in place?



It installs from the inside/top after removing the slide and some parts in the frame.

Either yours slipped out of the factory without it or someone had it apart and lost it and reassembled the pistol without it.

I seriously question the CZ quality control program or lack of. They are systematically shipping guns with parts that have burrs or out of tolerance, based on my two recent P-01 Omega warranty returns and now apparently missing parts! May have to go with Smith & Wesson going forward, who has an excellent customer service Dept from my recent experience.

All of you are correct about the retaining pin. I looked at my CZ 97B and saw the hammer retaining pin, so it looks like the one on my P-01 was never installed. These are my first two CZs so I don't have a lot of experience with them, but as I said, it's disappointing that the QC is so sketchy as to allow a missing part that caused a total failure of the firearm. Anyway, I just filed a warranty claim with them, so let's see what happens next. Thank you all for your helpful replies.

Well, I managed to push the pin back in by manipulating the hammer, but you can clearly see that the retaining pin was never installed.

Hongrn- sorry to hear of this & good luck with your warranty submission- think you’ll be taken care of if all the other warranty reports we’ve seen here are a guide. 

Please keep us updated to your progress

Will do sir. Thank you.

Yeah good luck with S&W. My last 2 S&W's went back multiple times before they were fixed. One returned twice and one returned 3 times so I can tell you plenty about who has a better warranty dept and it ain't S&W.
Of course they all do have their QC issues from time to time so there's that as well.

I really like the way the M&Ps feel in my hand.  Just don't care for the patterns they shoot on paper.

Except for the little Shield 9MM pistols.  Those little suckers shoot groups.  If S&W can make they tiny Shields shoot good groups they could make the full sized 9s and .40s shoot good groups.

I've been into mine enough (Pre B rebuild/polishing/spring changing/SAO conversion, etc.) that I'd be replacing that pin myself vs. trusting some shipping company to get it to CZ and back to me without losing it.  More than a couple times in the last few months I've waited a month to get a package that usually takes 4 days and watched (tracking number) it move back and forth on the map multiple times while passing within 6 or 8 miles of my house as they take it 150 miles south into NC or north into MD, PA, etc.

Shipping something valuable always worries me.

I have had that happen once, when a gunsmith with little CZ experience forgot to reinstall the retaining pin. It only took one or two magazines full for the hammer pin to move so far out I felt it on my thumb, which is how I knew something was wrong.
Just to clarify, you said it is a relatively new gun, but:
1. Are you the first owner?
2. Have you disassembled it and removed the sear cage at all?
3. Has anyone else disassembled it for any reason at all?

I haven't had mine apart in quite a while, but my recollection is the retaining pin is trapped in its hole when the sear cage is installed, so there is no way for it to come out when assembled. Either it was never there, or it was never re-installed after someone had it apart.

1. I bought the gun brand new from a reputable shop at the end of September, so I'm the first owner and th gun 2 months old.
2. I've owned guns for over 40 years, and have not ventured into doing any type of repairs myself. Field stripping for cleaning is all I do in terms of disassembly.
3. No to your third question.

Thank you.

This is the part you need:  https://shop.cz-usa.com/hammer-pin-retaining-peg-75-850420026001.html

It’s not hard to install, plenty of videos on Youtube showing how to disassemble and re-assemble once the peg is in place.
