If you want this, then sell your Glock and pick up a glock MOS instead.


Trust me, it's going to be cheaper in the end, and the pistol will have more resale  value when you go to sell it down the road being a factory MOS unit.



As for if you really want to mount a red dot on a none MOS frame, then have the slide milled for the specific red dot that you plan on mounting.

Hence the MOS adapter plate and red dot sight mounted on the MOS slides, looks like ass, since you end up with huge gaps between the front and back of the red dot to the slide isntead, not to mention the gap line of the MOS plate to the slide as well.



Way cleaner look isntead, when the slide is milled for the specific red dot going to be used isntead.
