Looking to get some sights from 10-8 for a handgun.
They say you need a diamond file to get through their uber-tough coating.
All the diamond files I see on Amazon have shit reviews. Local Lowes doesn't even have any. Starting to feel like this is some sort of rare and specialized equipment...

For you fellas that have installed 10-8 sights- what diamond files did you use, and where did you purchase them?

Apparently you can also use a diamond hone, so I'm also toying with the idea of that as well.
