I don’t have CK Arms stainless steel grip but I do have SVI all stainless steel built limited gun. Decided to go all stainless steel thinking that I don’t have to worry about rusting, but wrong! I can see sign of rust on the grip (coated) and on the slide rear serration despite wiping it with silicone impregnated cloth every after match but it didn’t work. Not to mention I only had less than 1k rounds in it.
