🔴 Glock 20 MOS Red Dots – Precision Optics for Maximum Power

When you carry the Glock 20 MOS, you’re already packing serious stopping power. Now it’s time to pair that power with precision.

At Mounts Plus, we stock a curated lineup of red dot sights built specifically for the Glock 20 MOS. These optics are designed to deliver lightning-fast target acquisition, reliable co-witnessing, and long-term durability — all with seamless fitment to your pistol’s factory slide cut.

Whether you’re prepping your G20 for EDC, backcountry protection, or tactical use, the right red dot makes all the difference.

🟢 Why Add a Red Dot to Your Glock 20 MOS?

The Glock 20 MOS is made for optics. The Modular Optic System (MOS) lets you easily mount a red dot sight without custom slide milling. But not all red dots fit the same — and not all work well with high-powered 10mm recoil.

Our red dots are chosen for:

• MOS-ready mounting with or without adapter plates

• Hard recoil compatibility — built to handle 10mm energy

• Low-profile design for faster sight picture

• Top-tier brands like Holosun, Trijicon, and Leupold

• Co-witness support with suppressor-height iron sights

🛠️ Direct Mount vs Plate-Mounted – What’s Better?

Feature	Direct Mount	Adapter Plate Setup
Profile Height	Lower	Higher
Weight	Lighter	Heavier
Durability	Fewer parts — more secure	More hardware = more variables
Co-Witness Potential	Easier with low-profile optic	Depends on plate + optic height

Pro Tip: The Holosun SCS mounts directly and gives you the lowest, most secure setup for the Glock 20 MOS.

❓ Frequently Asked Questions (FAQ)

Do these red dots fit the Glock 20 MOS directly?

Some optics — like the Holosun SCS — mount directly without a plate. Others, such as Trijicon RMRs, may require a compatible Glock MOS plate.

Which Glock 20 generations are compatible?

These optics fit Gen 4 and Gen 5 Glock 20 MOS pistols that have the factory optics-ready slide.

Can I co-witness with my iron sights?

Yes, if you use suppressor-height sights or an optic with a built-in rear notch (like some Holosun and C&H models).

What’s the best red dot for Glock 20 recoil?

The Trijicon RMR Type 2 and Holosun SCS are both built to handle full-power 10mm loads without losing zero.

Is installation difficult?

Not at all. Most users can install these at home using the included hardware. Just follow the torque specs and use threadlocker.
