This is the pistol-slide question: your optic is cut for the Docter / Noblex footprint, and the slide in front of you is milled for the Shield RMSc pattern. A Docter/Noblex optic is larger than the RMSc micro cut, so it will not sit on an RMSc slide.

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