I've worn my Glock 33 in a Crossbreed Supertuck for over 5 years, pretty much every day for most of that time.
The only finish wear is right at the edge of the kydex. There's a thin line on the slide that looks "polished". It's less than 1/8" wide.
Personally, I could care less. It shows that the gun has been doing its job. Almost a mark of honor. It's a "work" gun not a beauty pageant entry.
