C&h Plt Sa Xdm Osp To Holo 407k/507k

The C&H Precision Plate for Springfield Armory XDM OSP to Holosun 407K/507K is a precision-engineered mounting solution designed for shooters who demand a direct optical interface on one of the market's most robust duty and competition platforms. This adapter plate bridges the gap between Springfield's open-source platform (OSP) footprint and popular Holosun reflex sights, eliminating the need for separate risers or jury-rigged mounting solutions. Law enforcement and military end-users rely on this type of direct-mount technology to maintain zero integrity, reduce stack height, and streamline maintenance in the field.

C&H Precision manufactures this adapter using precision-machined steel or hardened aluminum construction, engineered to exacting tolerances that ensure repeatable, zero-shift performance across thousands of rounds. The plate is designed to interface directly with the XDM's OSP-cut slide while providing a solid, co-witnessed mounting surface for either the Holosun HS407K or HS507K reflex sight—both industry-standard options for duty and tactical applications. The minimal profile reduces overall weapon package height compared to riser-based systems, improving co-witness capability and reducing parallax-induced aiming errors during dynamic shooting scenarios.

This plate is ideal for shooters who have already invested in either 407K or 507K glass and want seamless integration without modification. Installation is straightforward—the adapter drops directly into the XDM OSP footprint, and the sight bolts down using standard Holosun mounting hardware, requiring no gunsmithing or additional tools. Both duty shooters and competition pistol enthusiasts benefit from the robust construction and repeatable hold-zero performance that C&H Precision's manufacturing standards deliver. Compatibility is limited to Springfield Armory XDM, XDM Elite, and XDM Compact models equipped with the factory OSP cut.
