Greetings, wise ones. I am looking at buying a Gen 4 Glock 30. The dealer says it’s new. The finish on it looks shabby. The dealer said, “It’s just dry. That’s normal for a Gen 4 until you put some oil on it.” I have a Gen 3 and a Gen 5. I know nothing about the normal Gen 4 finish. Please look at the attached pictures and let me know what you think. Is it “dry” and therefore fine? Or is the dealer wrong?
