I am not sure if this is the right place for this thread but here goes. Has anyone mounted a FF on a XD/M ? I took mine off a .22LR rfile (where it was working fine) and bought the Burris mount and put it on my XDM 3.8. I noticed that the red dot was "way high" in the viewing window, I had to move my head down to the floor and look up through the FF to even see the dot. I tried adjusting the elevation screw and that moved it a littler but nowhere near where it should be, i.e. resting over the front sight post. I set it back for repair thinking it was out of calibration or somehow broken. Kudoes to Burris - they sent me a brand new FF shrink wrapped and everything. Very cool. So I set that on the mount and screwed in the 2 screws and guess what - same problem! Any ideas - will the FastFire work on this pistol ? Anyone tried it? Thx!
