Is this mark on my glock 17 slide normal?

Noticed this mark on my slide today. Not sure if it is normal.
It looks like a hairline crack, running from the little hole in the slide out to the face.
i doubt it really is a crack; but would rather be safe than sorry.

I have nothing to compare to and it doesn't appear to be there on any images i find on google.
To all the other glock owners out there, is this normal?

I also own a lot of guns and am employed but I just checked my Gen 2 Glock 19 and Gen 3 Glock 21 and neither had a similar mark but the slides on both have a slightly different profile. Can you clean the area a bit to see if that helps? How old is the pistol?
 
Hi.

The pistol is only a few months old. Round count around 1400-1600.

I can't say for sure if the mark was always there, I just noticed it after this range session; but I feel like I would have noticed it earlier had it been there.... maybe not though.

That area is quite clean, there are some small fibres in the picture but those are just from qtips. Using a little plastic pick there is a noticeable lip or catch when moving over the area.

For reference I probably should have mentioned this is a gen4, I think the location of the hole is different on previous generations.

Thanks for your help with this

Can you feel anything with a fingernail? I honestly can't tell if it's a crack or an optical illusion. Maybe take another picture with natural light if possible.
 
OP, if you want to find a crack, pour rubbing alcohol (not while your smoking;)) over the area and pay attention to the evaporation rate. The alcohol is thin enough that it will flood a crack and not evaporate as quickly as the rest of the area. (crack will highlight momentarily as "wet")


For what it's worth, it doesn't look cracked to me.

Another way is to take a qtip and go up and down in the whoikd be damaged area while turning it the opposite way your going and the cotton on the qtip will catch the crack. It's what they do to find cracks in bows.
 
I've had a chance to look at the pictures on a better monitor and I agree with some of the the posters that it's probably just a machining mark.

Here's the crack I thought I was originally seeing:

But I edited out just the mark on the top (which I think is the machining artifact), and the "crack" in the conical hole disappears.
