Functions fine, finish isn’t durable at all - Killer Innovations Velocity Glock 19 Threaded Barrel

I put this in my gen 3, Glock 19. I hadn’t even fired a shot yet, and noticed that just racking the side, caused marring to the finish. As time (one year) went on, the finish at the breach kept getting worse. It functions perfectly with my Obsidian 9 attached, so I can’t ding it for that, but, you’d think that a barrel at this price point, would look at least as good as my 35 year old Glock 17 gen 1. I could almost understand some wear near the muzzle, but right at the top, next to the logo??? No thank you. I’ll just go with a nitrated barrel that’s half the price, if that’s what my money gets me. It’s not like I’d even notice a difference in accuracy. I’m a good shot, not a sharpshooter.
