I still don't think it will co-witness well with stock sights. JagerWerks milled my RMR pocket .185" below the slide surface (same depth as the factory rear sight dovetail) and I could barely see my .225" Dawson P09 front/.245" Dawson Glock MOS rear sights. The factory #3 front is ~.150" tall. So unless the pocket is milled over 1/4" deep, there would still only be a sliver of iron sights to use.
I also wonder how much thread engagement the right side mounting screw has, since it sits right over the extractor. Mine is well clear and doesn't block the extractor pin which is a plus.

For reference, here's my co-witness with .225" tall front sights and a .185" deep rmr cut. It's really only usable for slow target shooting, so I've since replaced with in a .265" Dawson P09 front/.280" Ameriglo Glock rear.
