Stainless Slide For PT111?

[Benjaminm0110]

I've been looking around for a stainless or titanium slide for my Taurus PT111 Millenium Pro. I live in washington and it tends to get pretty humid here in the summer, plus I carry IWB. I recently purchased my pistol in blue, not realizing I would have to deal with the rust factor. So far so good but im noticing some slight discoloration on the taurus logo on the side of the slide. I was at a gun show recently and found my same model with a stainless slide for only $40 more than I paid for mine but no one would just sell me a slide. Any ideas would be greatly appreciated! Thanks everyone!
