Questions & Answers
Will this fit both my Glock 19X MOS as well as my Glock 19 gen 5 MOS?

Yes. think of it like the #2 plate that came with your MOS optic ready Glock with the difference that it adds a guard to the front and integrated rear sights

Will the vortex defender st fit on this? Expert Answer

The Radian Weapons Glock MOS Radian RMR Guardian Optic Guard is designed to mount optics that use the Trijicon RMR footprint. The Vortex Defender ST uses the Deltapoint Pro footprint and would not be compatible with this mount.

Best optic plate for the MOS by Michael, Verified Owner, January 6, 2024
This is the 2nd Guardian and Six optic plate and sights I've purchased. I've owned CHP, FCD, and now this optic plate. The Guardian hands down, is the best optic plate I've used. Insanely durable, best mounting mechanism for an optic and the Six sigh...

Product Info for Radian Weapons Glock MOS Radian RMR Guardian Optic Guard & Sights

GUARDIAN OPTIC GUARDimage

MOUNT WITH STUD-LOK INTERFACE + TRU-SEAL

The Radian GUARDIAN Optic Mounting System provides unprecedented protection for your pistol red dot optic. Machined from 7075 aluminum & hard anodized, the design provides top/ front/side impact protection. Optional back-up sights, provide an unobstructed, irons forward sight picture.

Our STUD-LOK threaded stud/nut mounting interface is the most secure system on the market. This provides much longer thread engagement, greater hold down power, with increased shear resistance.

TRU-SEAL eliminates the need for an added sealing plate. Pre-installed O-rings on the mounting screws hold the plate watertight to the slide, sealing out moisture, eliminating corrosion in the mounting threads.
