6 Best Red Dot for Glock 47: Precision, Speed, and Durability in One Sight
The Best Red Dot for Glock 47 should combine speed, precision, and reliability under all conditions. Having tested dozens of optics across range sessions and defensive scenarios, I’ve narrowed down the options that truly complement the Glock 47’s balanced recoil and modular MOS system. This guide reviews the top performers in terms of clarity, battery life, ease of mounting, and real-world use.
🧭 Top Picks: 6 Best Red Dot for Glock 47 of 2025
Here’s a quick summary of the top sights tested on my Glock 47 MOS slide:
Each sight in this lineup has been range-tested for zero retention, dot clarity, and ease of co-witnessing with Glock factory or suppressor-height sights.
1. Trijicon RMR Type 2
The RMR Type 2 remains the gold standard in pistol optics. Trijicon’s forged aluminum housing and patented shape deflect impacts away from the lens, making it one of the most battle-proven reflex sights for Glock pistols.
Specs
My Experience
When mounted on my Glock 47 MOS, the RMR Type 2 zeroed perfectly in under 10 rounds. Its dot remained crisp in full sunlight and retained zero after several hundred rounds. The tactile adjustment clicks are ideal for duty use — no mushiness, no drift. I’ve also submerged it briefly during training; no fogging or water intrusion.
Community Feedback
Reddit users on r/Glocks and r/CCW repeatedly praise the RMR’s unmatched reliability, often calling it the “Glock of optics.” It’s expensive, yes — but if you’re running a duty pistol or defensive setup, it’s worth every cent.
2. Holosun 507C X2
The Holosun 507C X2 is one of the most popular optics for the Glock 47 — and for good reason. It offers multiple reticle options, solar backup power, and tank-like construction.
Specs
My Experience
Mounted directly on my MOS plate, the 507C required no additional adapter. I particularly love the multi-reticle system — the 32 MOA circle helps with rapid acquisition during close drills, while the 2 MOA dot nails precision at 25 yards. The Shake Awake feature worked flawlessly; even after a week in the safe, the sight powered on instantly when drawn.
Online Comments
On AR15.com and Reddit’s r/RedDots, shooters often compare the 507C favorably against the RMR for its modern features at half the price. Many report perfect performance after thousands of rounds.
3. Leupold DeltaPoint Pro
Leupold’s DeltaPoint Pro stands out for its crystal-clear glass and wide window. This optic excels for shooters who prioritize situational awareness.
Specs
My Experience
On the Glock 47 MOS, the DPP’s taller window made dot reacquisition significantly faster during controlled pairs. It’s also one of the easiest to replace batteries on — no need to remove the optic, thanks to the top-loading design. My only gripe is weight; it’s a bit top-heavy for concealed carry but outstanding for competition.
Community Notes
Competitive shooters in USPSA and IDPA consistently recommend the DPP for its lens clarity. On GlockTalk forums, several users note it survives slide rides better than expected for its size.
4. Swampfox Justice RMR
Swampfox Justice is one of the most underrated optics for Glock 47 shooters. It offers an RMR footprint, strong construction, and vibrant reticle brightness.
Specs
My Experience
In testing, I mounted the Justice using a standard Glock MOS RMR plate. It held zero after 500 rounds of 9mm, and the dot stayed sharp even under midday light. The glass coating reduces glare effectively, and button placement is intuitive — something many budget sights miss.
Community Insight
Many Redditors on r/CCW call this optic a “budget RMR clone that actually works.” Some law enforcement trainers even recommend it for recruits on a budget.
5. Vortex Defender CCW
Vortex recently released the Defender CCW — and it’s a strong contender for everyday carry Glock 47 users. Known for its clear glass and lifetime warranty, it’s a safe investment.
Specs
My Experience
Although the Defender CCW needs an adapter plate, it’s one of the most robust micro red dots I’ve tested. The glass clarity rivals the DPP, and the brightness range transitions smoothly from indoor to outdoor. I dropped mine on gravel during testing — no shift in zero, no cracked lens.
User Opinions
Vortex fans on forums consistently highlight its no-questions warranty. It’s smaller than the RMR, making it ideal for concealment without sacrificing function.
6. Aimpoint ACRO P-2
The ACRO P-2 from Aimpoint is one of the most rugged enclosed emitter optics available. It’s fully sealed, making it ideal for law enforcement or harsh environments.
Specs
My Experience
While the ACRO P-2 sits slightly higher on the slide, it’s the toughest optic I’ve used. During wet range sessions, open emitters like the RMR fogged slightly, but the ACRO’s sealed design stayed crystal clear. The side battery tray is also a brilliant feature — tool-free swaps without losing zero.
Community Discussion
Tactical users on r/Guns and pistol-forum.com regularly list the ACRO P-2 as their duty optic of choice, citing its “tank-grade durability.”
⚙️ How to Choose the Right Red Dot for Your Glock 47
Selecting the Best Red Dot for Glock 47 depends on your intended use. Here are key factors I recommend considering:
1. Mounting Footprint
The Glock 47 MOS uses the Glock Modular Optic System. Look for optics with an RMR footprint (e.g., Trijicon RMR, Holosun 507C) for direct fit. Others, like the Aimpoint ACRO, require an adapter.
2. Dot Size
For defensive use, a 3–6 MOA dot balances speed and precision. Smaller dots (2 MOA) excel at longer ranges but can slow acquisition.
3. Battery Life & Access
Choose models with top or side-loading batteries. This prevents losing zero during replacement.
4. Durability
For duty or harsh use, enclosed emitters (like the ACRO P-2) or forged housings (like the RMR) are ideal.
5. Budget
High-end optics like Trijicon and Aimpoint exceed $500, but models like Swampfox Justice or Holosun 507C provide 90% of the performance at half the cost.
❓ FAQs
1. Does the Glock 47 MOS require an adapter for most red dots?
Most modern RMR-footprint optics mount directly using the Glock MOS RMR plate. Others (like RMSc or ACRO) need an adapter.
2. What’s the best dot size for a Glock 47 red dot?
3 MOA is the sweet spot — small enough for precision but fast enough for defensive shooting.
3. Can you co-witness Glock iron sights with these optics?
Yes, especially with suppressor-height sights. The RMR and Holosun 507C co-witness perfectly.
4. Are enclosed emitters worth it?
For duty or outdoor environments, yes. The ACRO P-2 and Holosun 509T prevent debris or moisture from blocking the emitter.
5. How often should I replace red dot batteries?
Even with 50,000-hour ratings, replace annually for peace of mind — ideally during spring cleaning or before training season.
6. Can I use these optics for competition?
Absolutely. The Leupold DPP and Trijicon SRO dominate in competitive shooting circles due to their large windows.
🧩 Conclusion
Finding the Best Red Dot for Glock 47 isn’t about chasing specs — it’s about balancing rugged reliability with personal shooting style.
For most shooters, the Holosun 507C X2 offers the best mix of price, performance, and features. If money’s no object, the Trijicon RMR Type 2 is still the undisputed king of durability. For duty-grade protection, the Aimpoint ACRO P-2 is unbeatable.
Whichever optic you choose, pairing it with proper zeroing, Loctite on mounting screws, and regular battery checks will keep your Glock 47 performing flawlessly for years.
