I have the new High gloss model and when I picked it up from my FFL, there was a white, powder like build up on the forward end of the left side of the slide near the muzzle. After getting it home. I removed the marks and stored it away. The very next day I found that this substance had returned and was a little harder to remove. It has been doing this for the past several days. I don't know what this is, why it keeps returning, and how to keep it from coming back. Any ideas, or does it need to be returned?
