Nice work on the sight. Have you used it yet.
This makes me happy I sold my mill. Know I would be doing these things to my guns.
Be careful with milling into your slide too deep. You need enough thread contact so the sight doesn't snap off during recoil. With Glocks, you can't go too far down with the RMR because of the way the extractor is set up.GREAT, now I gotta figure a way to get my Glock slide into work..........
