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.
