View Full Version : Is this crack common on Glocks?

Both my Glock 19 Gen3 (2009) and 26 Gen 3 (2011) have what looks like a hairline crack near the channel. It doesn't appear to go all the way through the metal into the channel, but the "cracks" are in the same place on both guns. Seems strange to me. I've tried rubbing both areas with CLP and alcohol to no avail.

I'll go ahead and answer the question before it's asked. No, I've never let the firing pin snap forward.

Both guns function just fine. I'm curious if anybody else has seen this on their Glocks?

I have the same thing on my 26 but the others don't have it.
It looks more like a scratch than a crack on my gun.

A crack in that area would go all the way to the edge. If you can see a crack on the vertical side it is a crack otherwise a tool mark.
My newest G26 Gen 4 with a couple of hundred rounds only has the same mark, it doesn't go to the edge, I have no concern.

Shoot the thing, try to wear it out.
If you do, Glock will fix it.

I checked my g19 and did not see any marks like that.

I see what you're talking about and can't figure why there would be a crack there? It's not a hight impact point, so I'd suspect a hairline fracture in the finish?

A drop of radiopaque dye, in the crack, cutting it in half and looking at it under an x-ray woud say for sure what it is a crack in the metal.

I dont see any marks in the pic, I must be blind LOL... at anyrate why is it that all these threads lately are nothing but complaints about Glocks,.. and why do so many people think they have to go over every millimeter of their guns and look for some sort of flaw or defect... just shoot the gun and enjoy Im so sick of "is this a crack" or my guns broke and dont throw brass just right or theres dirt on my glock and Im gonna send it back to glock... if it goes bang each time the trigger is pulled then there is nothing wrong with your Glock...

Both of those look like scratches that might result from letting the punch slip off of the striker sleeve as it is depressed during the process of disassembly.

+1 I agree. Good call.

....or assembly at the Glock factory. I just bought a brand new G19 yesterday that has a similar scratch.:shocked:

If you have used factory ammo only, Glock will give you a new slide.

Dumb question, but how do you "let the firing pin fall forward"?

I don't buy that.
I have the line on a brand new G26.
Unless the factory has a tool to compress the striker and make assembly faster and leaves that mark sometimes.
I never had a punch slip on me when I take them apart. The way you use a punch momentarily to compress the sleeve is not prone to slipping.

It could also be a scratch on the mold that transfers over, if its cast. I am not sure if the slides are cast or milled out of billet.

Just checked, my G26 Gen 4 looks identical with the same mark.

I just checked my EDC G26 (Gen 3) and it doesn't have the scratches.

Thanks for sharing though.

Dumb question, but how do you "let the firing pin fall forward"?

You let it "fall" forward by holding the slide muzzle pointed down and depressing the firing pin safety. You let it "snap" forward by pressing the firing pin lug to the rear as far as it will go then letting it snap forward. This can cause damage to the slide, firing pin, and/or firing pin safety.

I have the same thing on my Gen4 26 and because it's a new gun (for carry) I have never had to take out the firing pin, safety pin, or ejector.
So it couldn't be that.

That was the point I tried to make, it comes from the factory scratched.
They must have some tool that compresses the striker sleeve for faster assembly, time is money.

Regardless of "where" it took place and "who" did it, my point still stands- the scratch must come from the/an instrument used during the process of depressing the sleeve.

Spot on. It's called a "Tool Mark". It could be from a person slipping a tool across the part during assembly or from a robot. And it doesn't make any difference what operation was being performed when it happened. A tool mark is a tool mark. :tongueout:

Just for ***** and giggles I just pulled the slide off my G19 and G23. Guess what? BOTH have the tool mark.

It's probably got something to do with BTF.

I pulled the slide from a random Glock and found the same. Don't sweat it.

My g19 with 5k plus rounds fired doesn't have it.

My 8 month old Gen 3 G19 has it and my Gen 3 G17 with old tupperware box does not. Looks like a little scratch to me. Can't say I really care. Every time my booger hook is applied to the bang switch it does its thing.

Had a Glock with the same mark, there was no physical ridge that could be felt and looking at it through a magnifying glass I could tell it was only a slight surface scratch. On the other hand I also have a Glock that has a serious internal scratch in the extractor slot for some reason.

In the assembly process maybe some fixture is used to hold the slide and this often results in a slight mark. I doubt if Glock assembles pistols the same as we would, but rather have all sorts of fixtures, holders, whatever to speed up the process.

Every Glock I've ever owned has had that same mark. It's a tool mark and nothing to be concerned with so don't worry, your gun is fine!

I have the exact same thing on my USA made G17. It makes me think that not all the components are USA made.

Hey guys,

Put your microscopes and high power magnifers away, then shoot the frickin gun. It will be ok . It is a piece of metal and plastic. It is NOT something sent from the heavens above.
Please let me know when YOU can produce a world class pistol for under $500.00.

Looks like a hairline,pre-KaBoom strato stress fracture.I wouldn't shoot it.Send it back to Glock ASAP !

no

most glocks have that mark. I assume its from the striker hook
