It's called slide peening and is relevant on all calibers of Glocks. Nothing unusual.

I have yet to see it on any of my 9mm Glocks (I currently have 12), and I have one with a documented 65000 rounds through it, and another with 22000, and all any of them show, is some very slight finish wear in the same spot on the underside of the slide, where the 31 was "peening". By "slight finish wear", I mean you can see a slight discoloration in the finish, and neither is worn to bear metal. The 31 was way past that and definitely hammering the metal.
I actually have more +P+ 9mm (which is basically loaded to 357SIG pressures) through those two high count guns, than I had 357SIG through my 31.
The 31 on the other hand, was continually leaving enough of a burr, that I cut my fingers a couple of times cleaning it. I was told it was common with the .40's, but never really saw any on the couple I looked at, and certainly nothing like what my 31 was doing.
This was my 31 slide when it first started to happen. The two silver spots just back from the front of the ejection port is what youre looking at. Its already past the finish and into bare metal, and hammering it over the edges. It actually got quite a bit larger than what you see here and just before I got rid of it, I just dont have another pic of it. ..
This is my one 17, with just over 60000 rounds through it, whren this was taken. You can see the slight wear marks on the finish in the same place the 31 was being battered.
