NF PLATE+NS 509T FITS GLOCK FS MOS

When your Glock MOS slides forward, the right optic mounting plate and backup sights make all the difference. This Night Fision combo delivers a self-illuminated front sight paired with a milled steel plate engineered for 509T optics. Whether you're in Vallejo or Sunnyvale, TacticCAL handles your FFL transfer in Sunnyvale while you focus on your setup.

Backup sights built alongside optics

MOS slides demand precision mounting. This plate-and-sight assembly locks your 509T optic in place while the backup night sight stays visible for emergency transition. Tritium vials glow independently—no batteries required. Installation takes standard tooling on most Glock full-size frames. Shooters handling private party transfer process paperwork often upgrade their sighting systems while FFL paperwork clears. This combo covers both duties in one system. TacticCAL is your local gun shop in the Bay Area.

Frequently asked questions

Will this optic plate fit my full-size Glock with an MOS cut?

Yes. This plate is engineered specifically for Glock factory MOS-cut slides. The 509T mount centers on standard MOS footprints. Verify your slide carries the MOS designation before ordering.

Do these night sights work in complete darkness?

Tritium sights emit a glow without power. They're brightest in darkness but remain visible in daylight through paint-filled ramps. This combo provides both capabilities in one sight picture.

Does TacticCAL help with CA compliant firearms?

Yes — TacticCAL specializes in California-compliant handguns from the DOJ Roster and PC §32100 exempt single-action revolvers. Find FFL dealer Morgan Hill at TacticCAL.
