6 Best Red Dot For Glock 47 in 2026: Mounting & Compatibility
Best Red Dot for Glock 47 is a question I get constantly from shooters who want to maximize the performance of Glock’s full-size MOS platform. The Glock 47 blends duty reliability with modular flexibility, but the optic you choose will determine how fast you acquire targets, how well you track recoil, and how confidently you shoot under stress.
I’ve spent extensive time testing pistol optics on MOS systems, including hard-use range sessions, low-light drills, and rapid-fire strings. In this guide, I break down six optics that actually perform on the Glock 47—focusing on real-world durability, mounting compatibility, and shooting characteristics like parallax behavior and window clarity.
Top Product List: Best Red Dot for Glock 47
Trijicon RMR Type 2

The RMR Type 2 remains the benchmark for durability in pistol optics. It’s simple, rugged, and proven across military and law enforcement use.
Specs:
Pros:
Cons:
My hands-on notes:
The RMR handles recoil impulse exceptionally well. Even during rapid strings, dot tracking is predictable. Parallax shift is minimal at practical handgun distances. Co-witness is easy with suppressor-height irons due to its moderate deck height.
What people say online:
Most shooters trust it for duty use. The biggest complaint is battery access, but reliability outweighs inconvenience.
Mounting clarity:
Direct MOS mounting requires an RMR plate. Once installed, it sits solid with no movement.
Aimpoint ACRO P-2

The ACRO P-2 is a fully enclosed emitter optic built for extreme conditions and duty-grade reliability.
Specs:
Pros:
Cons:
My hands-on notes:
This optic shines in harsh environments. Rain, dust, or mud won’t block the emitter. Parallax is extremely well controlled. The deck height is higher than RMR, so co-witness requires taller irons.
What people say online:
Users love its reliability but note the slightly boxy sight picture compared to open optics.
Mounting clarity:
Requires MOS plate adapter for ACRO footprint. Once mounted, it’s extremely stable.
HOLOSUN 507C

The 507C is one of the best value optics, offering advanced features at a mid-range price.
Specs:
Pros:
Cons:
My hands-on notes:
The side battery tray is a major advantage. Reticle flexibility helps new shooters acquire the dot faster. Parallax is slightly more noticeable than premium optics but still acceptable.
What people say online:
Highly praised for value and features. Some debate long-term durability compared to premium brands.
Mounting clarity:
Directly compatible with RMR footprint MOS plates.
HOLOSUN 509T

The 509T brings enclosed emitter protection with a titanium housing for durability.
Specs:
Pros:
Cons:
My hands-on notes:
The enclosed design prevents lint or carbon buildup. Parallax is well controlled. The window is slightly smaller than open optics, but clarity is excellent.
What people say online:
Users like the balance of durability and price compared to ACRO.
Mounting clarity:
Requires MOS adapter plate. Not direct RMR footprint.
Leupold DeltaPoint Pro

The DeltaPoint Pro offers one of the largest windows in the pistol optic category.
Specs:
Pros:
Cons:
My hands-on notes:
Target acquisition is extremely fast due to the large window. Parallax is minimal. However, the higher deck height requires taller suppressor sights for co-witness.
What people say online:
Shooters love the window size but note mounting limitations.
Mounting clarity:
Requires MOS plate specific to DPP footprint.
EOTECH EFLX

The EFLX is EOTECH’s entry into pistol optics, focusing on speed and clarity.
Specs:
Pros:
Cons:
My hands-on notes:
Glass clarity is excellent—one of the best. Parallax is well controlled. The buttons are easy to use even with gloves.
What people say online:
Mixed feedback: great clarity, but long-term durability still being evaluated.
Mounting clarity:
Compatible with RMR footprint plates on Glock MOS.
How I Tested / Evaluation Criteria
Parallax:
I tested each optic at varying distances, focusing on off-center aiming. Premium optics like the ACRO and RMR showed minimal shift, while budget options exhibited slight deviation at edge-of-window positions.
Co-witness / Deck Height:
Deck height determines how easily you can co-witness irons. Lower optics like RMR allow standard suppressor sights, while taller optics like DPP require extra height considerations.
Durability:
I evaluated recoil resistance through rapid-fire drills. Forged housings and enclosed emitters consistently outperformed lighter open designs.
Battery:
Battery life and access matter. Side-loading and top-loading designs significantly reduce maintenance hassle compared to bottom-loading systems.
Brightness Range:
Each optic was tested in bright sunlight and low-light conditions. NV settings are useful but less critical for civilian shooters.
Glass Quality:
Clarity, tint, and distortion vary widely. EFLX and DPP excel in clarity, while others show slight blue or green tint.
Controls Ergonomics:
Button placement and tactile feedback matter under stress. Larger, glove-friendly controls performed best.
Mounting Ecosystem:
Footprint compatibility is crucial. RMR footprint remains the most versatile for Glock MOS users.
How to Choose the Right Red Dot for This Gun
Choosing the right optic for a Glock 47 depends heavily on your intended use. Duty, range, and defensive carry all demand slightly different characteristics.
First, consider durability. If you plan to run the pistol hard—training courses, duty carry, or defensive use—prioritize optics like the RMR or ACRO. These are built to handle repeated recoil cycles and environmental abuse without losing zero.
Next is emitter type. Open emitters are lighter and offer larger windows, but they can be blocked by debris. Enclosed emitters like the ACRO P-2 or 509T eliminate this issue entirely, making them ideal for harsh conditions.
Window size also plays a major role. Larger windows like the DeltaPoint Pro make target acquisition faster, especially for newer shooters. However, they often come with increased size and higher deck height.
Battery design is another critical factor. Top or side-loading batteries reduce downtime and eliminate the need to re-zero after changes. This is a practical advantage often overlooked.
Footprint compatibility is essential with the Glock 47 MOS system. The RMR footprint remains the most widely supported, giving you the most flexibility with mounting plates and aftermarket support.
Finally, consider your shooting style. If you prioritize speed, go for a large window optic. If you prioritize ruggedness, choose a proven enclosed or forged design. The ideal optic balances these factors without introducing unnecessary compromises.
FAQs
1. Does the Glock 47 require a mounting plate?
Yes, the MOS system requires adapter plates for most optics depending on footprint.
2. What is the best footprint for Glock MOS?
RMR footprint is the most widely supported and easiest to work with.
3. Are enclosed emitters worth it?
Yes, especially for duty or harsh environments where debris can block open emitters.
4. What MOA size is best?
3–3.5 MOA is ideal for balanced precision and speed.
5. Can I co-witness with standard sights?
No, most setups require suppressor-height sights for co-witness.
Conclusion
Choosing the Best Red Dot for Glock 47 comes down to balancing durability, clarity, and mounting compatibility. After extensive testing, I consistently find that optics like the RMR Type 2 and ACRO P-2 dominate for hard use, while options like the 507C and EFLX provide excellent performance for less demanding roles. The right choice depends on how you actually run your pistol—but any of the optics in this guide will give you a serious performance upgrade when properly mounted and zeroed.
