This is the pistol-slide question: your optic is cut for the Shield RMSc footprint, and the slide in front of you is milled for the Docter / Noblex pattern. The RMSc micro cut and the Docter/Noblex pattern are different, so an RMSc optic will not fit a Docter slide.

Match the optic to the cut instead of forcing it. An rmsc-cut slide or plate, or a docter-footprint optic keeps the sight seated square so it holds zero under slide cycling.
