Glock 21 ejection question

[hipwr40]

I've got my eye on a used G21 that appears like new with one exception. The bottom of the ejection port has brass markings on it from the spent cases as they are ejected. Kind of like some of the new Steyr M series pistols I've handled.

Is this normal for a .45 Glock? What can be done to fix it?

Completely normal.

Completely normal and easy to remove with any good bore cleaner. I use IOSSO and it removes it with one quick swipe.
