Reserved P365 SAS Optic Adapter Plates
  • Reserved P365 SAS Optic Adapter Plates

    SKU: P365SASAP-R

    PLEASE READ the installation manual found HERE


    This adapter plate will allow the mounting of the optics that use the Shield RMSc mounting pattern (like the Sig Romeo Zero, Swamp Fox Sentinel, and Holosun 407K/507K) on the Sig P365 SAS. Simply remove the factory rear sight and install the adapter with the included M2.5 x 8mm screws. You can then mount your optic to the plate with the included M3 mounting screws. It is required that you apply threadlock (we recommend Vibra-Tite VC-3)  to all hardware to prevent backing out. 


    PLEASE NOTE - Due to variances in Sig's dimesions of the SAS sight pocket, final fitting may be required. If you do not feel comfortable performing installation yourself you may send in your slide and plate to have us perform the installation. You will just need to pay for the cost of shipping.
