I'll stick to my guns, (pardon the pun), that the slide has been reParkerized. Forget the actual phosphate coating. The damage to the metal from being tumbled with sand is pretty blatant. Notice the difference in the grain structure on the close up photo as compared to the frame not to mention the battered sharp edges, dings and dents from tumbling with other parts. I saw the big tumbler at the 82nd Division workshops at Fort Bragg in the early 1980's and being a gun guy then as I am now, I was appalled but that's how it was. Just my 2 cents.
