Not normal. Call H&K Repair and have them sort it for you under warranty.
And let us know what they find!!!
Have you tried other ammunition?
I’ll definitely update here.
I haven’t tried other ammo, but I feel that the two types I have tried are different enough to conclude that this is a gun issue and not an ammo issue. I’ll try some non-budget, mid weight .45 if I have some time.
I called HK customer service today and was instructed to email them with a photo of my issue, along with the serial number of the Mark 23.
I also went to the range today and shot a good variety of ammo (pictured below). All of the casings had the primer/firing pin drag on them. I tried to orient the marks to the 12o'clock position.

Fascinating post! Please do keep up updated. Really solid picture and analysis of the issue.....fwiw
Interesting... thanks for sharing this.
Never saw "drag" marks like your pics. Of course the first question in taking the gun apart is the firing pin nice and smooth/rounded/straight?
