Hey Guys, just picked up a brand new Glock 19 gen 5 from my FFL today. It has the funkiest looking factory barrel I've ever seen in an unused barrel. Every Glock I have ever owned had barrels like mirrors. This one has a milky grey film running from chamber to crown. I have tried cleaning it up with every cleaning agent know to man, but it wont budge. Any ideas what it could be. Hopefully I can download a few pics.IMG_3383.jpg
