Iv had my G17 since xmas, it probably has 1500rds through it currently. I was looking at the bore, which is completely clean, and very shiny. But looking a little closer, angling my bore light so I don't get as much shine, I can see the actual finish of the inside of the bore, which is very blotchy and copper colored from the jackets. Since I usually only use CLP to clean it, I figured I should bust out the hoppes elite which says it removes copper on the label, cleaned for a good 5 min with that and its still blotchy. Is this normal?
