FAQs About Glock 23 MOS Red Dots

What red dots fit the Glock 23 MOS directly?
The Holosun SCS MOS, Trijicon RMR Type 2, and certain Leupold DeltaPoint Pro models mount directly without adapter plates.

Do I need taller sights when using a Glock 23 MOS red dot?
Not always. Many direct-mount red dots sit low enough for standard MOS sights, but suppressor-height sights provide a cleaner co-witness.

Is direct mounting better than using an adapter plate?
Yes. Direct mounting is more secure, reduces bulk, and ensures your optic sits lower compared to adapter plate setups.

What’s the best Glock 23 MOS red dot in 2025?
The Holosun SCS MOS and Trijicon RMR Type 2 remain top choices for their durability, clear optics, and direct fit for Glock MOS slides.

Can I install a Glock 23 MOS red dot myself?
Yes, if you have a torque driver and threadlocker. For those unsure, a gunsmith can handle installation and sighting quickly.
