C&H Plt Sa Xdm Osp To Holo 407K/507K
The C&H Precision Weapons adapter plate for Springfield Armory XDM OSP to Holosun 407K/507K bridges the gap between a popular duty/carry platform and some of the most reliable micro red dots on the market. If you've got an XDM OSP frame and want to run a 407K or 507K, this precision-machined mounting solution is engineered to get your optic sitting exactly where it needs to be—no guesswork, no shimming.
C&H Precision Weapons manufactures these plates in-house at their Coastal Georgia shop, holding each to CNC tolerances that matter when you're mounting glass. The 6061 aluminum construction is light and rigid, finished in MIL-SPEC Type III hard anodize that resists wear and corrosion through daily carry or range use. All mounting hardware is stainless steel, so you're not fighting rust in the field or at home.
Whether you're building a carry gun with a modern footprint or setting up a duty rig, this adapter plate handles the mechanical work so you can focus on the gun. It's the kind of detail that separates a cobbled-together setup from something you trust to function when it matters.

Frequently Asked Questions
Will this mount work with other red dots besides the 407K and 507K?
No—this plate is specifically designed for the Holosun 407K and 507K footprint on Springfield Armory XDM OSP frames. Using it with incompatible optics will result in poor fitment and an unsafe setup.
What comes in the box?
The listing covers the adapter plate itself and the stainless steel mounting hardware needed to attach it to your XDM OSP and secure your 407K or 507K to the plate.
Is this plate durable for carry or duty use?
Yes. The 6061 aluminum construction and MIL-SPEC Type III hard anodize finish are designed to handle the wear and corrosion that comes with everyday carry or duty handling. Stainless steel hardware won't rust under normal conditions.
Does this plate add significant bulk or weight to the gun?
The product facts provided don't include weight or height specifications, so we can't give you an exact number. Contact us directly if those dimensions are critical to your setup.
