Springfield Armory XD Mounting Plate Features The Springfield Armory XD mounting plate is engineered for pistols with the OSP or Optical Sight Pistol configuration giving those slides a direct adapter for mounting leading red dot sights. It is cut to the RMR and SRO standard footprint meaning it accommodates Trijicon s most widely used mounting pattern as well as Holosun optics built to the same footprint which opens up a broad selection of compatible red dots rather than restricting the pistol to one proprietary cut. The plate is designed to enhance practical accuracy by allowing the optic to sit low and close to the bore axis reducing parallax and keeping the dot s point of impact more consistent across distances. This is a genuine factory Springfield accessory engineered specifically for the OSP cut Springfield already machines into these slides. The plate is compatible across the XDM Elite XD and XD Mod 3 families so shooters do not need model-specific hardware if they own more than one OSP-equipped Springfield pistol. Because it uses the RMR and SRO footprint swapping optics later whether upgrading to a new Trijicon model or trying a Holosun red dot does not require a new plate in most cases. Installation follows the same OSP plate-swap process Springfield designed into these slides making it straightforward for an owner comfortable with basic pistol maintenance. For an XD XDM Elite or XD Mod 3 owner who wants to add or change a slide-mounted red dot this mounting plate delivers the factory-correct path to a Trijicon or Holosun footprint optic.
