I was all set to purchase a M&P CORE 9mm w/5 inch barrel because the slide is MOS ready and I have a Burris Fastfire III. Then I looked at the specifications which listed the optics that the slide is milled for and the one listed are: Trijicon RMR, Leupold Delta Point, Jpoint, Doctor, C-More STS, Insight MRDS. So does that mean my FF III will not work with this pistol or I will have to have additional work done to the slide? I checked the Glock 34 and it says pretty much the same thing.
