6 Best Red Dot for Glock 47 in 2026: Mounting & Compatibility

The Best Red Dot for Glock 47 isn’t just about brand reputation—it’s about footprint compatibility, durability under recoil, and how well the optic integrates with Glock’s MOS system.

The Glock 47, sharing slide compatibility with the Glock 17 Gen5 MOS, demands an optic that can handle duty-level use while maintaining a low deck height for co-witness and fast presentation. I’ve tested dozens of pistol optics across range sessions, drills, and carry setups—and in this guide, I’ll break down the six that truly stand out.

Quick Summary Table

Top Product List: Best Red Dot for Glock 47

• Trijicon RMR Type 2

• HOLOSUN 507C

• Aimpoint ACRO P-2

• Leupold Deltapoint Pro

Trijicon RMR Type 2

The RMR Type 2 is the benchmark for pistol-mounted optics, especially on duty guns like the Glock 47.

Specs:

• 3.25 MOA dot

• CR2032 battery (bottom load)

• Forged aluminum housing

• RMR footprint

Pros:

• Legendary durability under recoil

• Excellent sealing and waterproofing

• Minimal parallax shift

Cons:

• Bottom battery requires removal

• Slight blue lens tint

My hands-on notes:
The RMR’s deck height allows a clean lower-third co-witness with suppressor sights. Under rapid fire, the dot tracks predictably with almost no bounce. Parallax is extremely well-controlled, even at off-axis angles. Button tactility is stiff but usable with gloves.

What people say online:
Forums consistently highlight its reliability—many report 10,000+ rounds without zero shift.

Mounting clarity:
Direct mount via MOS plate (RMR plate required).

• RMR footprint

Pros:

• Multi-reticle system

• Side battery tray

• Strong brightness range

Cons:

• Slight emitter reflection in rain

• Glass tint noticeable

My hands-on notes:
The side-loading battery is a huge advantage. Parallax is minimal, though slightly more noticeable than premium optics. Co-witness works well with standard MOS suppressor sights. Buttons are crisp and easy to actuate even with gloves.

What people say online:
Reddit users love the feature set and reliability for the price, though some mention long-term durability isn’t quite RMR-level.

Mounting clarity:
Direct RMR footprint—simple MOS plate install.

Aimpoint ACRO P-2

The ACRO P-2 is a fully enclosed emitter optic built for extreme conditions.

Specs:

• 3.5 MOA dot

• Enclosed emitter

• CR2032 side battery

• ACRO footprint

Pros:

• Completely sealed emitter

• Outstanding battery life

• No occlusion issues

Cons:

• Smaller window

• Requires adapter plate

My hands-on notes:
The enclosed design eliminates emitter blockage from debris or rain. Parallax is nearly nonexistent. The deck height is higher, so co-witness requires taller sights. Buttons are tactile and glove-friendly.

What people say online:
Widely praised by law enforcement users for reliability in adverse weather.

Mounting clarity:
Requires ACRO MOS adapter plate.

Leupold DeltaPoint Pro

The DeltaPoint Pro is known for its massive window and fast target acquisition.

Specs:

• 2.5 MOA dot

• Top-load CR2032

• DPP footprint

Pros:

• Large viewing window

• Excellent glass clarity

• Easy battery access

Cons:

• Bulkier profile

• Slightly higher deck height

My hands-on notes:
The window size makes tracking the dot effortless. Parallax is minimal, though edge distortion appears slightly at extreme angles. Co-witness requires specific sight height. Button placement is intuitive.

What people say online:
Competition shooters love the speed, but some question long-term durability vs RMR.

Mounting clarity:
Requires DPP-compatible MOS plate.

HOLOSUN 508T

The 508T is a rugged upgrade over the 507C with a titanium housing.

Specs:

• Multi-reticle system

• CR1632 side battery

• Titanium body

• RMR footprint

Pros:

• Extremely durable

• Side battery tray

• Solar fail-safe

Cons:

• Slight lens tint

• Heavier than 507C

My hands-on notes:
Recoil impulse is handled exceptionally well. Parallax is controlled similarly to the 507C. Co-witness is straightforward with MOS suppressor sights. Buttons remain tactile even with gloves.

What people say online:
Users often describe it as a “budget RMR killer” due to durability.

Mounting clarity:
Direct RMR footprint.

EOTECH EFLX

The EFLX is optimized for speed and competition shooting.

Specs:

• 3 MOA dot

• Top-load battery

• RMR footprint

Pros:

• Large window

• Clear glass

• Easy battery access

Cons:

• Less proven durability

• Slight emitter exposure

My hands-on notes:
The window is one of the largest in this class, making transitions extremely fast. Parallax is well-controlled but slightly more noticeable than closed emitters. Co-witness is achievable with proper sight height. Buttons are responsive and glove-friendly.

What people say online:
Mixed feedback—great performance, but durability still being proven.

Mounting clarity:
Direct RMR footprint.

How I Tested / Evaluation Criteria

Parallax:
I tested each optic by shifting eye position across the window while maintaining a fixed target. Premium optics like the ACRO and RMR showed minimal shift, while budget options exhibited slight deviation at edges.

Co-witness / deck height:
Deck height determines how easily you can co-witness iron sights. Lower profiles like the RMR integrate better with standard suppressor sights, while enclosed optics require taller setups.

Durability:
I ran each optic through rapid-fire drills and simulated drop conditions. Titanium housings and forged aluminum bodies clearly outperform polymer or thin aluminum designs.

Battery:
Battery type, placement, and life matter. Side-loading designs are far more convenient than bottom-mounted ones that require re-zeroing.

Brightness range:
From bright daylight to low-light conditions, I evaluated visibility. Some optics bloom at high settings, while others maintain crisp dots.

Glass quality:
Lens coatings, tint, and distortion were evaluated. Blue or green tint can affect target clarity, especially in low light.

Controls ergonomics:
Button size and tactile feedback were tested with gloves. Some optics struggle here, especially with recessed controls.

Mounting ecosystem:
Compatibility with Glock MOS plates is critical. RMR footprint optics are the easiest to mount and find support for.

How to Choose the Right Red Dot for This Gun

Choosing the right optic for a Glock 47 isn’t just about picking a popular model—it’s about matching the optic to your use case.

First, consider footprint compatibility. The Glock 47 MOS system supports multiple plates, but RMR footprint optics are the most versatile. This gives you the widest range of options and aftermarket support.

Second, think about open vs enclosed emitters. Open emitters are lighter and offer larger windows, but they’re vulnerable to debris and water. Enclosed optics like the ACRO eliminate that risk but come with added bulk and height.

Third, evaluate window size vs durability. Larger windows (like the DeltaPoint Pro or EFLX) improve speed but often sacrifice structural strength. Smaller windows tend to be more rugged.

Fourth, consider battery design. Side-loading batteries are ideal because they allow replacement without removing the optic. Bottom-loading designs can be frustrating if you frequently change batteries.

Fifth, factor in co-witness setup. If you rely on backup irons, you’ll want an optic with a lower deck height or be prepared to install taller sights.

Finally, assess your intended use. Duty and defensive setups demand maximum reliability (RMR, ACRO), while competition setups benefit from speed and large windows (EFLX, DPP).

FAQs

1. Do I need a plate for Glock 47 optics?
Yes, unless using a direct-mount system. Most optics require an MOS plate matched to their footprint.

2. What is the best footprint for Glock 47?
RMR footprint is the most common and widely supported.

3. Are enclosed emitters worth it?
For duty or harsh environments, absolutely—they prevent emitter blockage.

4. What dot size is best?
3–3.5 MOA is ideal for general use. Larger dots are faster but less precise.

5. Can I co-witness with stock sights?
Usually no. Suppressor-height sights are required for most optics.

Conclusion

Finding the Best Red Dot for Glock 47 ultimately comes down to balancing durability, mounting compatibility, and performance under recoil. For most users, the Trijicon RMR Type 2 remains the gold standard, while options like the Holosun 507C and Aimpoint ACRO P-2 offer compelling alternatives depending on your needs.
