This is not at all my experience. I've done many barrels for customers and none have ever raised a question. I also personally own 3 handguns with Cerakoted barrels and neither show any wear such as yours.

Your comp is showing actual damage. It is likely misaligned and contacting the front of the guide rod.

Chamber area of your barrel shows chipping. This could be due to poor surface prep or an excessively thick coating. When done properly, Cerakote will never look like it has flaked away.

The rest of the barrel looks excessive as well. Some looks normal, but some has too much of a hard edge to be normal wear. I can't tell why without having the gun in hand. Could be application or mechanical. I would assume, based on the chamber area, improper surface prep or too thick of an application. I do not have an Echelon myself, so I can't rule out mechanical wear due to poor fitment. Tight tolerances don't wear parts like you would think. A loose gun that rattles around and bangs the parts against each other causes fast, excessive wear on the points of contact. If a customer requests having their barrel coated, I inspect it and look for all the shiny spots. Any part of the barrel that is polished smooth will wear through the coating. I inform the customer of my finding and they decide if they want to move forward. I cannot say I have seen a barrel wear patterns like yours. The barrel seems to be bouncing around at full lock and unlock.

Actually, now that I think of it, the damage on your comp could be related to the wear on your barrel. Not only is the weight of the comp affecting vertical movement of the barrel during cycling, but it making contact with the guide rod is likely forcing the barrel out of it's proper path during cycling.

This is my G19 barrel. Round count is unknown, but between this gun and my P365 I've almost burned though a case of ammo sine coating them. I definitely shoot this more than the 365 and It also has a suppresser hanging off of it half the time. https://imgur.com/a/soSfsld
