Broken slide stop

I was shooting the CZ75 today and the slide was locking back on a partial magazine. I noticed it was pushed out a little. Pushed it back in and the slide went forward. I finished the magazine and decided I needed to get home and see what was going on. On the drive home I realized that the stop was away from the frame on one side yet the end of it was still protruding as much from the other side. Hmmmmm.

Good news is that they are only 39 bucks from Midway.

Dang, that Sucks. I'd give Cz a call before I dropped that 40$.

They might just send you one.

Estimated round count?

Someting wong. Check your barrel/slide engagement surfaces for debris or any reason why the barrel feet are hammering the slide stop so hard when it goes into battery.

It is under 5K rounds. None, other than a few factory, have been heavy loads. Most were in the 3.5-3.7 gr of Red Dot range.

Boy 5k is barely broken in for a 9mm. I would definitely want to see what Cz has to say.

I will be contacting them tomorrow. Handgun is only 3 years old.

Looking online it seems people have one of two opinions on this. They either had a slide stop break early or they never broke one. Doesn't seem to be a middle ground. Some feel it is recoil spring related. I may replace mine just in case.

That slide stop takes a beating. My Sig 1911 slide stop was a problem till I installed a Wilson bullet proof stop. Different gun I know. May not have a strong enough recoil spring.

WOW. In literally millions and millions of rounds shot and watched shot in IPSC matches, I have seen
a LOT of different broken guns, but never before that part, broken that way on any design based on 1911 or HiPower.
The little tit on sstop that engages the mag follower to lock back would occasionally break on 1911s, but almost all of those
I ever saw were Colts and made in the 80s, when their quality was at a fairly inconsistent level. Haven't seen that failure
in probably 20 years.

I trust Ed Brown 1911 small parts head and shoulders above Wilson these days, even though I have two WONDERFUL and dead
reliable Wilson custom 1911s. I have personally seen two Wilson 1911 extractors that had missed heat treat, were soft,
wouldn't hold tension for 40 rounds. Wilson replaced them without batting an eye......BUT

I will be quite surprised if you get any grief from CZ, my bet is they just send a new part, although they may want to see
why it happened, don't know. I know Alice personally and she is a real good person, and I am also friends with the Sales
Manager there. All the CZ folks I know (at the top of the company) are REAL gun people, I have shot in competition with
several of them for years, off and on, mostly off, now.

+1 for "5K is barely broken in". I have multiple semi auto pistols with more than 40K+ on them and running like a sewing
machine, several in the 70-100K range, one GCup broke a rear sight at about 65K and the slide stop tit at maybe 15-20K,
nothing else. The others have been "break free". As to MIM parts, one at about 40K is a Kimber 1911, very early production,
all MIM internals are still humming along. I put a 2 lb trigger on it in about 1998 and it still holds 2 lbs and perfect. I trust
MIM parts, but I suppose some may be faultily made.

That's a new break point on a slide stop for me. First I have seen or heard of.

One maker's slide stop that would break about every 5K-6K rounds was that of the S&W metal-framed autopistols like the 39, 59, 659, 4506 et al. These had the plunger spring and detent assembled into a gallery in the slide stop itself, and held in place by a roll pin. The detent assembly would spring out of its gallery upon shaft breakage, and the slide would start locking back in mid-magazine. They are drop-in parts, specific to the model. They weren't very expensive.

They consider it normal wear. Will be getting a new one from Midway soon.

Brad,


The slide stop is considered a wear item. Meaning because of the function of the firearm it will eventually break. The only thing to do to keep it from breaking is making sure there isn’t any debris build up on it and where it functions with the barrel. To buy a new one visit our webstore at www.shop.cz-usa.com


Unfortunately our computer system is down so you won’t be able to check the site until tomorrow or Thursday.

The stop and the corresponding slot in the barrel lug were always kept well lubricated. Amazing is that the 1911 has 3X the rounds and never an issue.

I love the handgun but this is a major irritation.

Brad,

I did a little searching and got a lot of references to broken slide stops.

Then I found this:
"Mike Eagleshield of CZ USA advised me a couple of years ago that he highly recommends going to about a
14 to 16-lb recoil spring and that this does alleviate the problem with slide stops breaking."

I know Mike and he is very experienced with these guns, was (still?) one of their factory gunsmiths there in
KC. I'd trust this info, assuming it really came from Mike.

So is comes broken from the factory, and it's up to the user to install the parts that will keep if reliable. I'd be making another call to CZ, this time starting off something like "Listen here, &^&^%-stick........"

14 # is factory standard.
Most loads were on the mild side so I'm not sure what really happened. Looking online it does seem this is a problem in some of these handguns.

Bill, I may well look at a 15-16 # spring.

Not their design. They just build it.

Also, you might be surprised that they don't have total control over the factories, except the
Dan Wesson one here. I haven't talked to Alice recently, and perhaps things have changed, but
years ago they had to largely take what the Czech factories put out, could ASK for changes, but they
were not always done by the factories. AFAIK, they do NOT own the factories in the Czech Republic,
and get guns from several different suppliers. They didn't seem to want to talk much about the exact
relationships between CZ-USA and the various firearms factories, but it is definitely not like S&W who
100% own their factories and decide exactly what gets made.

For instance, I told the sales mgr that I would buy one of their mini Mausers if they could get rid of that
ugly single stack, built in mag hanging down and ruining the lines of the gun, IMO. He said that they had
asked if a flush double stack mag like a normal 98 Mauser could be done and the factory said "No", and
that was that.
