Holosun 509PLT-FNX45 adapter plate mounts for 509 series to FNX45
Holosun 509PLT-FNX45 is an adapter plate designed to mount Holosun 509 series enclosed pistol optics onto FNX-45 Tactical optics-ready slides. It creates a dedicated, low-profile interface so the 509-series red dot can be integrated directly on the FNX-45 platform without extra spacers or improvised solutions.
The plate uses a precision machined steel construction with a corrosion‑resistant finish, ensuring correct alignment and a secure fit of the optic under recoil and during hard use. The geometry is tailored specifically to the FNX-45 Tactical optics-ready interface and the Holosun 509 footprint, helping maintain proper sight height and natural handgun handling characteristics. Holosun 509PLT-FNX45 is available at Professional Optics in Split at competitive pricing, with fast shipping across Europe and expert support for choosing and mounting Holosun optics on your FNX-45 Tactical.
