G45 barrel wear..

[Mr. Booshie]

The wear is just lots different than the Gen 3's and 4's..it gets shot plenty, and like most have said, the wear showed up after the first 50 rounds. Maybe the cost for having a "marksman" barrel....lol

This is correct. The marksman barrel locks up tighter than the older models.
If you look at the gap between the barrel and the slide it is much smaller now, that’s what causes the marks.
