Good tip Bill,
But on every 1911 style pistol I have owned in the last 20 years, I do the same thing to prevent/stop making the idiot scratch.
I take a dremel or small extremely fine file and just take the sharp point off the slide stop lever where it lines up with the notch.
I take reassembly a little slower than some at that point too, but rounding the tip ever so slightly will prevent a scratch. Were talking maybe .0001-.0002, just enough to take the sharpness of the point off
