I don't have any problem with holster wear either, but it wouldn't matter if I did.
Keep in mind that the Stealth uses the same stainless slide as does the standard model except that it's coated.
So even if the finish did wear, I wouldn't care because the slide would still be the same regarding resistance to corrosion.
What I get with the Stealth is a black pistol that has little "shiny stuff" to expose itself as a gun ("He's got a gun!") if my shirt comes up a little high by accident.
The Stealth in it's all black color can easily be taken for a cell phone.
