is this a defect? WARNING - LARGE PIX INSIDE

[ndeeya]

hi all,

just successfully field stripped my gun for the first time since i bought it 2 days ago.

i've learned a lot about the trigger mechanism and why the take up is so long, just by removing the slide.

during my inspection of the trigger mechanism, i noticed a sizeable nick/gouge/imperfection on the frame right next to the "Trigger Bar Disconnector" (part #42).  i have not fired this gun yet, and i was wondering how it got there.  also, there are some parallel scratches on part#42... are they normal?


any speculations and theories are welcome.

Will this "defect" affect the performance of my gun?  if so, is it covered under warranty?

thanks for the help guys.
cheers,

Guess it all depends on how pristine you want your gun to be.

That part of the weapon doesn't have any function.  The "chip/cut" is in the polymer, right?  It shouldn't affect a thing.  

As best I can tell, its a cosmetic problem.  

You may want to send these pictures to CZ and ask them.

Ndeeya,

I am looking at the rear rails of my field-stripped 100 at this very moment, and do not see the gouges that appear on your 100 in the images. They are definitely not normal. Do the gouges look like moulding defects or the result of physical abuse during the assembly process?

One possible concern would be if the gouges are deep enough to adversely affect the strength of that right rear rail. It is conceivable that the gouge has created a weak spot that, in time, would cause the rail to crack under the stress of repeated firing and slide movement during recoil.

It would not hurt to give CZ-USA a call to discuss the situation.

the gouge definitely something that happened after the mfg process.

if it doesn't affect the performance/durability of the gun, i'm willing to live with it.

i guess i'll give cz a call.

thanks.

I just pulled my -100 (1997 manufacture) apart, and it has a 'ding' in the same spot as yours.  Mine is about 1/4 the sixe of the ding you have.

Go to the www.cz-usa.com site, click the little mail icon, and send them the link to this thread.  I would like to see what they have to say about it.

I don't have a CZ-100, so I can't look to check.  But there aren't any RAILS in that area of the gun, are there?  Don't they stop a bit farther forward?  

The CZ-100 seems, unlike the other CZ, to have the slide OUTSIDE the rails...  (Like I said, I don't have one, and never really paid attention to that aspect/feature of the gun.)  Sure looks like slide outside in the image above.

walt,

actually the rails do stop... but they continue again to surround the trigger mechanism housing.

so there are fore rails and aft rails.

cheers,

I didn't look closely enough at your photos.  They show up in the next t

• last photo.  

I'll bet that CZ says it NOT a problem.

Ditto here, Walt. I am a bit leery about CZ-USA's willingness to fix factory-originated cosmetic problems after my experience with them concerning the large gouge on the outside surface of my first 100 as described here.

With regard to ndeeya's problem, on subsequent reflection I do not think the gouge on the rear rail will lead to any kind of structural failure, as the rear rails do not bear the brunt of the recoil-generated stress. On www.hs2000talk.com, a question was posed about the long-term durability of the rear plastic slide rails on the Springfield XD9/XD40. A factory rep replied that the front rails, which are metal, bear the bulk of the longitudinal recoil stress. This does seem to be the case, as I have not noticed any unusual stress-related wear marks on the rear rails of both my CZ 100 and XD40 Tactical, which currently has northward of 2000 rounds through it.
