Night Fision Precision Optic Mounting Plate: 509T to Glock Full Size MOS
The Night Fision Precision Optic Mounting Plate is a dedicated adapter designed to mount Holosun 509T red dots and other optics with compatible footprints directly to Glock full-size and compact MOS-equipped pistols. If you're running a modern Glock with a factory optics cut and want a secure, no-wiggle mounting solution for your 509T, this plate bridges the gap between your frame and your glass with the kind of precision fit that serious shooters demand.
Built from 17-4 stainless steel and finished with a nitride coating, this plate is engineered to handle the repeated recoil impulses of centerfire pistol shooting without movement or degradation. The engineering is straightforward but critical: machining tolerances are kept tight to eliminate play, and the material choice resists corrosion and wear in field conditions. At 0.2" thick, the plate sits low enough to maintain a proper sight picture while providing the rigid interface your optic needs to stay zeroed shot after shot.
Installation is handled with included mounting screws and an installation tool, so you can get your 509T up and running without a trip to the gunsmith. The plate works with Glock full-size and compact MOS models—note that Slimline MOS pistols are excluded, so verify your frame before ordering.

Frequently Asked Questions
Will this mount work on my Glock 43X MOS or other Slimline models?
No. This plate is designed for Glock full-size and compact MOS pistols and is not compatible with Slimline MOS models.
What red dots does this plate support?
The plate is designed for the Holosun 509T and other optics that use a compatible mounting footprint. If your optic shares the 509T footprint, it should mount securely.
Do I need a gunsmith to install this?
The package includes mounting screws and an installation tool, so you can complete setup in the field. However, if you're unfamiliar with mounting optics to your pistol, professional installation is always an option.
What makes 17-4 stainless steel and nitride coating the right choice here?
17-4 stainless steel offers excellent strength-to-weight ratio and corrosion resistance, while the nitride coating adds a hardened surface that resists wear from repeated shooting and handling. Together, they ensure your mounting plate stays zero'd and functional through years of use.
