I have had my G23 for abou 7 years. Only put exactly 26 rounds through it. I pulled it out of the safe today for the 6 month wipe down. I notice the barrel hood as some small spots on it. Like tiny indentions. 2 small spots. But the black finish is in the indentions. So I am thinking they were there before it left the factory Anyone else have small anomalies in theirs? I plan to swith this out to my edc and these spots have me worried that rust might start there? .
