Interesting...perhaps another option would be to mill off the offending lettering on the slides as long as the lettering isn't to deep.
That could work. I thought of putting it on the surface grinder
but didn't want to remove the square cut serrations on the
rear of the slide. I suppose I could take a slight "high power"
cut back to the first slide serration. The lettering isn't as deep
as the serrations.
