Is this a cratered primer from pressure? Or is it just a hard strike from a new Glock 19?

Thats the glock mark... a glock leaves it on every cap it busts for advertisement purposes... from the local friendly range to the hood, everyone knows when a glock goes pop :)
 
Here is a little better pic. I think it's just the firing pin and not over pressure. I don't see how any of my loads could have been too hot.

Striker fired marks. If there was pressure issues the edges of the primers would not still be rounded.
 
I see these a fair amount at my club and have been told (with what sounded like less than 100% confidence) that it was from a Glock. If anyone knows for sure I'd love to know how this happens. Does a Glock have some kind of rectangular edge around the firing pin?
 
I looked it up on google photot search. Commenters above are correct. It's glock mark.

I think it has more to do with how the barrel and slide unlock from battery position.
