The Springfield Armory XD OSP slide assembly (brand part no. XD4903) converts a 4-inch Springfield XD to the Optical Sight Pistol configuration, pairing the factory slide with a Crimson Trace CTS-1500 red dot already mounted and zeroed from the factory. Finished in black Melonite, this factory assembly gives XD owners a straightforward way to add a slide-mounted optic without sending a slide out for aftermarket milling. Because it uses genuine Springfield components, fit and function match what would be expected from a factory OSP model, making it a dependable upgrade path or replacement part for an existing 4-inch XD.
