Black Powder Coat Question

Attachment 191091
The other day I was at my local Powder Coating Shop and one of the colors I picked up was Black. I know there has been discussion about barrel abrasion. My question is has this ever ascertained as true with all black's? I would like to use black for my Glock and .300 Black.out. Thank you for any answers

No. Only unproven rumors.

I pc gloss Smoke's gloss black with no probs. I thought i read somewhere its the flat black that is a possible problem.
