The CHP Adapter Plate for Glock MOS is your solution for mounting a Holosun 509T red dot on a Glock MOS-cut slide. If you've invested in a modern Glock with an optics-ready platform, this precision adapter bridges the gap between your slide and the 509T optic, giving you a clean, secure installation without gunsmithing. C&H Precision Weapons manufactures these plates in-house at their Georgia facility, holding each one to tight tolerances on HAAS CNC equipment and running them through multiple quality checks before they ship.
Built from stainless steel with US-made mounting hardware, this adapter is engineered to hold zero and withstand the rigors of duty carry, competition, or the range. Whether you're running a Glock 17 MOS, 19 MOS, or another MOS variant, the adapter provides the interface you need to get your 509T dialed in. The precision machining ensures a snug fit without wobble—critical when you're staking your accuracy and reliability on an optics mount.
Installation is straightforward: the adapter sits between your slide's MOS pocket and your Holosun optic, secured with the included stainless hardware. No modifications to your slide or optic required. If you've standardized on Holosun 509T optics across your pistols and want to add your Glock MOS to that ecosystem, this plate gets the job done without compromise.
The CHP Adapter Plate is designed for Glock MOS slides. Confirm your slide is MOS-cut (has the factory optics pocket). If you're unsure which Glock models feature the MOS platform, reach out to us and we can help verify compatibility.
