Overview
Built for mounting a Holosun 407K or 507K on compatible GLOCK 43X/48 MOS pistols, this adapter plate provides a dedicated interface for adding a compact optic to a carry or duty setup. It is machined from 6061 aluminum, finished in MIL-SPEC Type III hard anodized black, and supplied with stainless steel mounting hardware. C&H Precision notes that fit can vary with plate, optic, and firearm tolerances, so dry-fitting before final installation is recommended. For shooters updating an MOS pistol with an aftermarket optic, it offers a straightforward mounting solution while also requiring attention to sight height and overall setup.

Considerations & Trade-offs
- This adapter is specific to GLOCK 43X/48 MOS pistols and Holosun 407K/507K optics, so it is not a universal mounting solution.
- Installation can be affected by tolerance differences across the plate, hardware, optic, and firearm; dry-fitting is recommended before full installation.
- Mounting an optic may change how factory iron sights work, and low co-witness height depends on the firearm, plate, optic, and slide cut.
- GLOCK does not manufacture, authorize, endorse, or warrant this product, so compatibility is provided by the seller rather than the firearm maker.
