How I Tested

I evaluated each optic over 60 days using my personal Glock 19 Gen 5 MOS equipped with Glock’s OEM MOS plates and an aftermarket C&H Precision plate for RMR cuts. Each optic underwent the following:

Drop and zero-retention tests (onto rubber mat from shoulder height)

Live fire: 1,000 rounds of 115gr FMJ (Federal)

Low-light assessment using Streamlight TLR-7A

Battery and brightness settings in indoor and outdoor conditions

Holster compatibility with Tenicor and Tier 1 Concealed rigs

After this testing, these five models consistently outperformed others in clarity, ruggedness, and mount fitment.

⁠

🥇 Trijicon RMR Type 2 – Best Overall

⁠

The Trijicon RMR Type 2 remains the gold standard for combat-ready red dots, and for good reason. Its forged aluminum housing and top-tier electronics have proven to hold zero even after thousands of rounds.

🔧 Specs

Dot Size: 3.25 MOA

Battery: CR2032 (4 years life)

Brightness Settings: 8 + 2 NV modes

Mount: RMR footprint

Weight: 1.2 oz

✅ Pros

Military-tested durability

True waterproofing (up to 20m)

Crisp dot even in bright daylight

❌ Cons

No auto-off

Slight blue tint in lens

🧠 My Experience

Mounted directly to my Glock 19 Gen 5 MOS using a Glock RMR plate, the RMR Type 2 never shifted zero even after 1,500 rounds. The tactile brightness controls are glove-friendly, and the housing deflects impacts beautifully. It’s my go-to recommendation for serious defensive use.

💬 Online Feedback

Reddit users frequently cite the RMR Type 2 as “the one optic that never dies.” Even law enforcement armorers I’ve spoken to still trust this sight for duty carry.

🥈 Holosun 507C X2 – Best Value for Money

⁠

The Holosun 507C X2 offers features usually reserved for optics twice its price. Its solar backup, multi-reticle system, and incredible battery life make it the best value choice for Glock 19 Gen 5 MOS owners.

🔧 Specs

Reticle: 2 MOA dot / 32 MOA circle

Battery Life: 50,000 hrs (CR1632)

Mounting: RMR footprint

Brightness: 10 daylight + 2 NV settings

✅ Pros

Auto + manual brightness control

Solar failsafe feature

Shake Awake technology

❌ Cons

Slightly bulky for concealed carry

Small lens compared to DPP

🧠 My Experience

Mounted on my MOS plate with C&H Precision RMR adapter, it co-witnessed perfectly with suppressor-height sights. During testing, I left it “awake” for 7 days — the auto-sleep feature kicked in flawlessly each time.

💬 Reddit Notes

Many users prefer the 507C over RMR due to price and battery accessibility. It’s a proven optic with wide aftermarket plate support.

🥉 Holosun SCS – Best Direct Mount Red Dot (No Plate Needed)

⁠

The Holosun SCS (Solar Charging Sight) is designed specifically for Glock MOS slides — meaning it mounts directly, no plate required. This gives it a sleeker profile and faster presentation.

🔧 Specs

Reticle: 2 MOA + 32 MOA circle

Power: Solar charging, internal rechargeable cell

Mount: Direct Glock MOS fit

Brightness: Auto-adjust with override

✅ Pros

Plate-free mounting

Auto solar recharging

Extremely low profile

❌ Cons

Higher upfront cost

Limited to MOS Glock models

🧠 My Experience

The SCS transformed my Glock 19 into a near-perfect EDC. No plate meant perfect factory height, allowing for faster holster draws. Even under cloudy conditions, the solar system maintained brightness perfectly.

💬 Online Discussion

On pistol forums, users rave about the direct mount fit and no-battery-swapping convenience. It’s the cleanest install available for Glock MOS slides.

🔹 Leupold DeltaPoint Pro – Best for Duty and Tactical Shooters

⁠

The DeltaPoint Pro has one of the largest windows in its class. For law enforcement, competition, or defensive users who prioritize visibility and ruggedness, it’s a top-tier choice.

🔧 Specs

Dot Size: 2.5 MOA

Battery Life: 300 hrs (auto motion sensor)

Mount: DPP footprint

Weight: 1.9 oz

✅ Pros

Huge viewing window

Motion sensor activation

Legendary Leupold warranty

❌ Cons

Slightly heavy

Top-mounted battery adds height

🧠 My Experience

The DPP’s glass clarity is unmatched. I shot through smoke and rain with full target visibility. Though slightly bulkier than RMR or 507C, its glass and auto-on feature justify the extra ounces.

🔸 Swampfox Sentinel – Best for Compact EDC

⁠

For those carrying daily, the Swampfox Sentinel is one of the smallest yet toughest micro red dots compatible with the Glock 19 Gen 5 MOS (via RMSc plate).

🔧 Specs

Dot Size: 3 MOA

Battery Life: 50,000 hrs

Footprint: RMSc

Weight: 0.6 oz

✅ Pros

Affordable and ultra-lightweight

Co-witnesses perfectly with low irons

Small window for long-range use

RMSc plates needed for MOS fit

🧠 My Experience

Perfect for minimalist carry. I ran it on my Glock 19 Gen 5 MOS using a Forward Controls Design RMSc plate — the fit was tight and precise. Despite its size, it handled recoil as well as optics twice its weight.

🧭 How to Choose the Right Red Dot Sight for Glock 19 Gen 5 MOS

When choosing a red dot for your Glock 19 Gen 5 MOS, consider:

Mounting Method:

Glock MOS uses adapter plates; ensure your optic’s footprint matches (RMR, DPP, RMSc, etc.).

Purpose:

EDC → Small profile (Swampfox Sentinel)

Range or Duty → Durability (Trijicon RMR, Leupold DPP)

Battery vs Solar:

For long-term reliability, battery-based RMR or 507C are proven; solar hybrid systems (SCS) are excellent for EDC.

Brightness Controls:

Manual is best for precision shooters; auto is great for defensive use.

Window Size:

Larger windows are easier for rapid target acquisition but bulkier for carry.
