I have

Happened a couple weeks ago while I was testing a bunch of different self defense loads through a chrono. I'm just now getting around to seeing what it actually was. After a "malfunction" I attempted to clear it and heard what sounded like a small piece of metal rattling around in the trigger area. Packed that gun up for the day.

The issue happened while shooting 147gr Remington Golden Sabre. I was on my 4th or 5th round and the gun was running like a sewing machine, as it had for the roughly 200 rounds I'd fired previously that range trip. This ammo was all running subsonically around 1050fps but the round immediately preceding the malfunction clocked at 1268fps and had a definite supersonic crack to it.

My conclusion? NEVER shoot Remington ammo again. Their .22 just flat out sucks, I've had issues chambering their factory PSP loads in 7mm Rem Mag (in a known good chamber) and now what I suspect was an overloaded 9mm round broke my Scorpion.

Oh well, off to order a couple new disconnectors...

Theres a few people out of 1000s that have had bad discons. You're not the first I've seen. CZ custom even makes a heavier duty version.

It could have been a combo of a weak disconnector and an overcharged round that caused it to prematurely break.

Your gun must be a carbine or an SBR with early 922r disconnector. They had improper heat treat, CZ USA will replace it for free.

Did your Evo have a very hard to cock trigger? It takes about 40 ft/lbs to cock mine.

You can pony up for the cz custom trigger and it solves many of the issues contained in this thread.

My issue is the feed lip on all my mags are either cracked or broken.  They still work surprisingly but I need to buy those metal lipped mags. 2 20 rounders and 3 30 rounders.  I'm gentle with these and hardly shoot them.  I think keeping loaded mags are stressing them.

The early factory magazines were known to have cracking feed lips.  The newer magazines have USA on the floor plate and have a slightly different shape on the back of the follower.  Call CZ and they should warrant them for you if you have the early ones.

The newer one is the mag on the right with the curved feed lips (when looking from behind) and the older model on the left has the angled feed lips.   If you have the older model with the angled feed lips, CZ should swap them out for you.

Here is a pic for reference:

40lbs to cock (charge) the gun? Damn dunno wtf with that, the main spring is only about 14bs which is about the same as most 9mm handguns.

Thanks, I just went through my mag stash. (4) 20 rounders and (5) 30 rounders I have are the old ones.

I did contact them about the disconnector and will bring the mags up when they contact me.

I just wish that cz custom could lower the price a bit on the disc., seems to be way overpriced.

A hot 147, maybe with a double charge, a lot of guns may have kaboomed.  Might be wise to send the whole gun back with  the fired case.  Have them fix the part and maybe look at everything else.

This is not necessary. I had this same exact issue. It was a bad 922r kit part that cz replaced no problem. It is not an ammo issue or anything else. Simply email them.
