I bought an M&P Pro the year before the C.O.R.E. came out. I would like to machine the slide to accomodate a reflex sight. I do not want the Mickey Mouse mounts they sell for the dovetail. I had a Glock that I bought a reflex sight for and knew it wouldn't hold up so I sent the slide to California to a place that machined Glocks for the reflex. I had a C-more sight. It looked great and worked great. Anyone on the forum done that or no someone that does it ? I do not need or want co-witness with iron sight.
