The Holosun OPMOD HS507C-X2 Reflex Red Dot Sight uses the Trijicon RMR footprint and would not be directly compatible with the P320 M18 which uses a Deltapoint Pro optic cut. To mount this optic, you would need to use an Deltapoint Pro to RMR adapter plate such as the C&H Precision Weapons adapter, which can be found linked below. If you do not want to use an adapter to mount an optic, I would recommend using a direct fit option such as the Eotech EFLX, Sig Romeo 1 Pro, Leupold Deltapoint Pro, Holosun SCS-320 and more.
