The Hammer on my gen1 Scorpion is showing some significant signs of wear, it’s almost as if the part was not hardened properly. I have around 800 rounds down the pipe. I emailed CZ customer support with some pictures and got this in response. “That is pretty common and we have yet to see any reliability issues resulting from the hammer wear.”
This just looks plain wrong to me. Firing the gun for just 800 rounds has created groves in the hammer you see visually and can feel with your fingernail, the metal on the hammer is flattening out in certain spots, it’s almost as if it wasn’t hardened at all. I believe CZ when they say that they have not seen any reliability issues, at least not yet, but this is not a part that I would expect to show these types of wear marks so early in the firearms life. At this rate i can see a reliability issue being created down the line. Does anyone else have symptoms of this? 
Edit: to fix pics |

Yeah, I agree with you. I'm sure it will run but not the type of wear I would expect to see at only 800rnds.

Hell, it should be less than that after 8000 rounds. Looks like it might be time for an aftermarket solution if that's how these wear under normal conditions...

Does it still shoot? If so, if it ain't broke don't fix it.

Oh yeah it shoots, it shoots quite well. I love the gun, it's a real blast at the range.
I traded another email with CZ customer support asking if the part was supposed to be hardened and my question was ignored. The response i got was pictures of other triggers with less wear than mine saying that it was normal. As for replacement CZ wants 99.00 for the replacement part via their web-store, that seems pretty steep. The trigger pack is ripe for aftermarket replacement so i think it's only a matter of time before alternatives are available. I am disappointed in the response from CZ to my inquiries, i will probably call them and see if i can talk through this with someone. I am still very curious if other are noticing this issue, there is a possibility here that i have a bad part. |

ETA pic: here's mine manufactured in 2013.. not as ugly as your sorry... but has the same wear on the side edge

I will have to give CZ Custom a call, thanks for the info. It's a very nice trigger - not cheap, but adjustable for pre and over travel, and makes the less than great factory trigger into something very nice to use! It also gets you three 922R compliant parts if you are SBRing your pistol, and don't want to buy the factory kit. Bob S. |

That kind of wear and deformation is utterly unacceptable. Period. There are others with hammers that are obviously not wearing like that and, it seems, a couple that are. That is a poor hardness condition and if the hammer face is that bad already...what is the sear interface gonna look like? That will trend to the UNSAFE very rapidly. Keep working on them until they acknowledge that this is a problem. Ask them, why doesn't a CZ-75 hammer look like that after 800 rounds....or an AR-15 hammer......or a Smith and Wesson revolver hammer? |

My world-feature pistol is already showing gouges in the hammer after less than 100 rounds. Definitely worrisome. I need to shoot it a bunch more prior to sending it in for the trigger pack swap. I'll ask them to change the defective hammer at the same time.

Between 300 and 400 rds through my carbine so far. Seeing a little bit that's troubling. Def something to keep an eye on as I plan to shoot the heck out of this thing.

My guess it has to do with the bolt having a square corner on it instead of a radius. The bolt corner acts like a chisel.

Mine is looking worn also with about 300 rounds through it. There is a nice little notch forming where the hammer meets the bolt. They should radius that area over to prevent this.

There is no way they properly heat treated these hammers. I'd be real curious as to what the Rockwell hardness is on these as compared to the pistol hammers. CZ better get on the stick and get this shit fixed ASAP. With my 41F suppressor ordering done and recently handling one at a gun shop, it was on my must acqire list but not until these issues are remidied.

It shoots fine. I am curious if the rush to get these world packs out the hammers were not up to snuff.
Have they started swapping the "world" packs out yet? |

This seems totally unacceptable.
This might be OK if you said you had 8000 rounds down the pipe, but 800
Then others chime in with fewer rounds with a similar story - not good. |

Picked up my Evo last Monday. Fired roughly 150 rounds or less. Starting to see wear on the hammer and the Bolt. . Not to thrilled to say the least. I guess I'll shoot till it stops working Or if it gets worse I'll contact Cz.
