If the pistol had been running along fine with no issues, look to manufacturer for remedy

That is case head separation of a case reloaded one too many times.

It's ammo related and Remanufactured is code for reloaded brass cases.
The cases can be worn ... it's a chance you take with "Reman" .
My advice ... don't buy anymore of that particular brand .

That is a typical out-of-battery failure, nothing more. The chamber of the CZ-75 fully supports the cartridge clear to the extractor groove. Since the blow-out is well ahead of the extractor groove the gun had to be out-of-battery. Did it blow out the magazine or damage the stocks too? Those would be typical damage in a case like this. My question is in what way was the slide stop damaged? I can see no reason why this would have happened. Did he possibly mean the magazine catch?
On my own CZ-75 Omega the trigger can be pulled and the hammer drop and fire the cartridge with the slide as far out-of-battery as 1/8", which explains how the gun could have fired in that condition! That is about how far the cartridge pictured had to be out of the chamber to blow out where it did. There may have been a problem with that cartridge that prevented the slide from fully closing, but that would be guesswork at this time.
All of my CS-75s and clones, I have several, will fire with the slide out of battery about the same amount, it is inherent in the design and does not indicate there was a problem with your friend's gun.
In case you question any of this I have my own CZ-75 Omega dis-assembled in front of me as I write these remarks, I am not depending on memory for details!

In 47 years of hand loading and a couple decades of hand loading for practical pistol competition, I have never had a 9mm (or any other straight wall or semi auto pistol case) suffer a head separation, and I’ve never been one to retire handgun brass until the case mouth cracks. Head separations are the result of case stretch, and straight wall cases exhibit almost no stretch. As such, case head separations are a bottle necked case phenomenon.
I have seen 9mm cases bulge and even crack from a hot load fired in a chamber that was unsupported over the feed ramp.

The OP’s case was the result of an out of battery fire.

You said slide stop in the original post and that was what I asked about! Do you really mean magazine catch now? If you mean the slide stop, in what way does it not work now? If it doesn't lock the slide it could be damage to the magazine or magazine catch. Can the slide stop be manually operated or removed from the gun normally?

Let me get more info
I'll let you know.

QUIT GUESSING! What makes you think the primer pocket is oversize, half of the case head is missing!
Did you even read and understand my post and the thorough explanation of why it was an out-of-battery event? But then I have only been gunsmithing since 1961, what do I know.
What are your qualifications??

Info
Only the extractor broke and couldn't be found.
No other damage seen by my friend. Slide stop and mag catch working.
The ammo seller told him send gun to CZ for inspection and repair they will pay.
Also said send ammo back for refund.
He bought his CZ 75 omega after checking out mine, I really like the gun. Never heard about the out of battery thing and it don't seem like a good thing.
Are there many other guns that can fire out of battery?
Thanks

I was going to buy one of the CZ 75s and a good friend(gunsmith) told me the gun was somewhat prone to firing out of battery. I heeded his words and bought another brand. To me the 9mm is already such a high pressure round...A kaboom like that could really mess up someone's day... Is the CZ a copy of the B Hi Power??

That sounds a lot better than your first post. Firing out-of-battery is most common with semi-automatic pistols. It depends on the timing of the dis-connector and type of locking system the gun has. Guns with the Browning type of locking are least susceptible. This is really rare because the cartridge enters the chamber it will usually seat freely and the slide close properly. It is when something keeps the slide from closing completely but is close enough the dis-connector doesn't prevent the trigger from dis-engaging the sear and allowing the hammer to fall.
As to the question about the CZ-75 being a clone of the Browning High Power, the answer is absolutely not!

Also
Forgot to mention he checked the remaining ammo found some with dents in the brass.
So it kinds all makes sense, seems like the round was not seated fully.

Repeat - did a trade with a Buddy.
Got a HiPower and a Planters Peanut Can of his lead bullet reloads.
A shooting I go!
Those rounds performed perfectly in the Browning.
They Broke the long extractor on my Model 39!

The extractor probably would have broken with any ammunition. The early, long, extractors are prone to breakage and nearly impossible to replace. A good reason not to shoot the M-39s and "S&W 9mm" model that was before the Model 39 designation, that were made before the 39-2. The easiest way to repair your early 39 is to replace the slide with one for a 39-2. Numrich has the slide.
