I have a world model, It has the same peening marks but weirdly after 200 or so rounds it has not changed in appearance ( I have shot 1000rds) my guess is that it smashed to the point it got work hardened.

This and the barrel thread issue made me back out from buying one two weeks ago. I'm just gonna sit this one out till CZ gets things straightened out. Whats wrong with the barrel? The muzzle threads aren't long enough to properly index a can. They need to be cut to the shoulder or need a relief cut after the threads. My bad, should have stated the CARBINE barrel threads. You have the pistol or carbine? |

Sounds crazy, but after handling an Inland paratrooper carbine, I have considered getting one of those..............despite the price of ammo..............still like the Scorpion, so I am going to watch this whole thing closely before I go all in

Hammer after 350 ( approx ) rounds. Not looking good. Gonna get ahold of CZ. I work in mechanical inspection so I am not gonna let them try to hose me with "Oh, it's fine." bullshit.
Still LOVING THIS GUN and I realize this is growing pains. This serial number is under 200.  |

I've sent an email with photos to the LE side of CZ orders maybe he can shed some light on this issue.
Eta my emails and pics have been forwarded to the sales and warranty dept. The fella at Cz who I go to for all my Cz purchases is just as stomped as we are on this issue. |

Anyone with the cz custom trigger job have an issue with their hammer? Just curious if the upgrade has the same issues. The normal hammer on cz website is $100 so might as well upgrade the whole trigger if the cz custom does not have this issue.

Finally got to shoot my scorpion, it seems to have the soft hammer problem. :/
Ill try to post pics once I figure out how. Anyone get a response from CZ on how they are going to handle this ? Thanks ETA: looked again and the back of my bolt carrier has wear also. |

Quote HistoryQuoted:
what did you like about the scorpion over the other competitors? Just curious as I have not shot of the competition yet. If this was meant for me, here is my experience with all three... They all worked great - we were mainly running 147 gr. Speer Lawman ammo, but some folks brought 115 gr. stuff - they all functioned fine. All were shot with either a SilenceCo Omega 9K or Octane 9 HD suppressor (on the Sig & the CZ, I tried both) The Zenith MP5 clone had a stock, so it was very easy to shoot - the other two were still pistols at this point, so they are kind of big, clunky pistols. 
The Zenith didn't have a last round bolt hold open, and it bothered me enough to notice. The clamp on rail section looked out of place to me, an after thought (which it is). The Sig felt good, but I could feel "stuff" spraying into my face. Since my goal for this style gun is a suppressed SBR, that was a major negative for me. I felt the Sig had a little less recoil than the CZ in pistol form, I think both would feel better with stocks. The CZ doesn't spit crap back, has a bolt hold open on the last round, and is a optic ready design (plus all the other mounting options with the rails). The fact that it's about half the price doesn't hurt either. I think all are good, but the CZ is the best choice for me. Bob S. |

From what I've seen on other Scorpions, they all show this, it breaks in a little, and then stops. The guys with the damaged hammers are a different story - some show no wear, others are plain ugly! My factory hammer was in good shape, but I replaced it to 1) get a better trigger and 2) get three 922R parts. Here is where you'll find the custom trigger/hammer pack (among other cool stuff). Hope this helps, Bob S. |

I'm not 100% sure, but I think that firing pin safety wear was there (or at least starting) before I changed out the hammer/trigger. To me, it seems CZ designed the gun to have some parts that need to wear in up to a point. Because it isn't a finely fit together piece of machinery, it has some tolerances that are meant to wear into each other a little. I guess time (and more ammo) will tell. If other folks want to pull their bolts and look - take pictures if they can, maybe we can get a better idea of what's "normal". Bob S. |

So far, my bolt wear has not increased NOR has the firing pin safety been beaten like yours appears to have been. I am throwing some more bullets downrange on Thursday to see how my mods to the facotry sight pan out....I'll get some pics after that so we can have an update. Projected round count will be about 600 rounds total after Thursday. |

I have about 300 rounds through mine as I just haven't been to the range much in the last year. Well I looked at the hammer and it appears to be similar to some of yours. I will be running about 200 or so through it early next week and will take another look at it. Interested in hearing what you guys find out from CZ. By the way, good job on the photos you guys have posted. I can't get a close up worth a darn. If it helps, my serial # B813xxx. |
