Well damn.  If I didn't know better I'd say that's a cracked breechface on a nearly new Glock.

9mm?

Round count?

Factory vs. reloads?

He claims brand new. Many are reporting the same thing on recently purchased Glock's.

Guy on that forum says all his Glocks have it.

Wow, yes, obviously cracked breechface, didn't know this was occurring in new ones.

Obviously Glock will fix these, once sent in...............kinda bullshit though, when I've got a 20 year old G17, with an untold thousands of rounds through it, breechface slightly battered (characteristic of high round count, not a problem), but sure as hell no cracks.

Read the thread linked in the first post folks.  It's a machining mark, not a crack.

+1,  clearly a machining mark......or maybe it is the reason that all Glocks will KABOOM.

Really?  Well hell, looked like a crack to me, from here.

I am a huge GLOCK pistol fan, but my gut feeling is the company is starting to "shit in their nest".

Just seems like a bunch of bullshit lately. Will stay a fan but I have NO plans on buying another GLOCK for a while. Just personal preferance.

Why could'nt they just leave the best damn fighting pistol on earth the fuck alone.

My G26 (NNB) has this extractor cut out so does my G21 (KEW). But when I looked at my G17s (DWY) breach face, it does not have it. The 17 has the older extractor that is flat and not the newer "loaded chamber" notched extractor. The 17 is a third gen but does not have the cut out. I even cleaned it looking for it and never saw it.

Has anyone found another that does not have it?

There are no stress marks around the end of that so called crack, clearly a machining mark geez.

Yeah, it could very easily be a shadow created by that deep machine mark.  I jumped the gun for sure.

Still a shame to see such a mark though, that's not been characteristic of their work in years past.

My 27 has the same kind of mark.  Thanks for the pic and thread.  The first dozen times I cleaned it I thought it was a carbon steak and used different solvents plus a brass tooth brush to no avail.  Now I can rest in piece.

Don't know that it is a sign of less quality, Mine travels at the same exact point as the OP's which is in direct alignment with the extractor. Maybe Glock does this for a purpose we are unaware of? Just another way to add the the perfection?

It's just a machine mark, and all this talk about Glock "going bad" is the same kind of stuff people say about how Chevy sucks blah blah blah but yet the Corvette has a very low PPh compared to other cars and will blow the doors off the "real" 'vette from the "good old days" without breaking a sweat.

All that being said, I am glad I have a Gen3. Why? I bought it used and I know the Gen 3's work. Not that the Gen 4's don't, but that I have something I trust, and that's all that matters as long as my trust is not placed ignorantly, and I don't feel that it is. Case closed for me.

No such mark on my new G27, born Feb 2010.  That thing doesn't even look fired yet anyway (didn't read the story but will later).

Just checked my austrian proofed 3rd gen glock 19 and sure enough lol.

It does appear to be a machine mark.

stripped my glock and took some crapy photo's [lighting sucked]









all that guys glocks may very well have the mark

EDIT~ before someone asks the white thing on the slide was a peice of a peice or rice one of the girls left on my table that i missed while whiping it down and got on the slide for the photo's lol

This thread made me go look! 8 Glocks, 6 have the mark, two don't. The two that don't are both older (Gen 1 G17, older G27, marked 40 SW). My Gen 3 19, 21, 22, 23, 27, and 35 all have the mark.

My 23 (1/08) has it. It's so fine I've never noticed it before.

I never noticed it before this thread either..seems quite a few newer made glocks have them

It is a bevel that is put there during the machining process.  It serves to control and determine the trajectory of the spent casing.  Some Glocks have them some don't.  If you compare serial numbers you will probably find all in a particular run have them.  Some older Glocks may have this some newer Glock may have it.  I'm sure there is a reason why some will and some won't.  Only Glock knows.  All my second gens have it.  It is nothing to worry about.  TXPO

Machine mark with over head lighting.

The not quite two year old Austo Proofed 19 I am currently wearing looks exactly the same.  I actually took it out to look at the firing pin chamfer because I did not realize they were cut that way.  The breach of my pistol is identical the pic in the OP, although it is dirtier, the firing pin chamfer and machine mark are both present.  I am assuming its twin 19 in the safe is the same.  Between the two of them several thousands of rounds have been fired uneventfully.

Here is an AZG*** Glock 17 1994.  I just got in exellent condition.  I would say less than 50 rounds threw it and the breach face has the milling marks.  Nothing new its fine.
