I did not look that way when I picked it up. Only after firing rounds and dry firing.Cylinder looks like it fell on the factory floor and bounced around.
If it's cerakoted, it could be a case of poor adhesion, like if the surface wasn't prepped well enough. Cerakote requires very good surface prep to get full performance. I would send it in. As good as Cerakote is, it will still wear faster than PVD, DLC, or nitride type finishes. It does seem to be way too much wear from only 150 rounds fired, unless you've also been dry firing the hell out of it.I should have probably mentioned that the cylinder is cerakoted.
