1. Triton Nautilus2
The Triton Nautilus2 immediately caught my eye because it integrates backup iron sights directly into the optic housing. This is a huge win for reliability on a concealed carry pistol like the Glock 43X MOS, as it means you always have a sighting system, even if the dot fails. It also boasts a true RMSc footprint, meaning no adapter plates are needed for a clean, direct mount.
Integrated Backup Iron Sights
The standout feature here is the built-in rear iron sight, milled directly into the optic. This provides a crucial redundancy for defensive use without adding extra bulk or requiring separate mounting. It’s engineered for a secure, zeroed backup should the primary dot wash out or the battery die.
Direct RMSc/407K/507K Footprint Mount
This optic uses a true RMSc footprint, allowing it to mount directly to compatible slides like the Glock 43X MOS and P365 without needing adapter plates. This ensures a more secure and repeatable fit, and the company states each batch is recoil-tested to simulate .50 BMG impulse.
Rugged Construction for Daily Carry
Crafted from 6061-T6 aircraft-grade aluminum, the Nautilus2 is built to withstand impacts and the elements, rated IP64 for dust and water spray resistance. It weighs a mere 4.66 oz, minimizing added bulk for comfortable concealed carry.
Always Ready with Shake Awake and Long Battery Life
With 10 brightness settings, including a daylight-visible mode, and a 50,000-hour battery life, this optic is designed to be ready when you are. The Shake Awake technology ensures it powers on instantly upon drawing your firearm.

2. ARORY RMU1
The ARORY RMU1 offers a versatile reticle system and robust construction, forged from 7075-T6 aluminum. It comes with an adapter plate specifically for Glock MOS, making it a straightforward option for those who might not have a native RMSc cut. The side-load battery is a practical touch that avoids the need to re-zero after a battery change.
Versatile Reticle Options
This optic provides a choice between a crisp 2 MOA dot for precision or an adaptable 32 MOA circle with a dot, offering flexibility for different shooting scenarios and personal preferences. It features 12 brightness levels, including NVG compatibility.
Durable Build and Shock Testing
Constructed from 7075-T6 aluminum and subjected to 3000G shock testing, the RMU1 is built for durability. It’s also IPX7 waterproof, ensuring it can handle harsh conditions encountered during training or daily carry.
Convenient Side-Load Battery
A key practical advantage is the side-load battery compartment. This means you can swap out the battery without removing the optic from your slide, preserving your zero and saving you time and hassle during maintenance.
Includes Glock MOS Adapter Plate
For owners of Glock MOS pistols that may not have a native RMSc cut, this sight includes the necessary adapter plate, simplifying the mounting process and ensuring a secure fit right out of the box.

3. C+H EDC
The C+H EDC is designed specifically with the Glock 43X/48 MOS in mind, offering a direct mount solution that simplifies installation. It promises a long battery life and robust construction, making it a solid contender for those who want a no-fuss optic for their carry pistol.
Direct Mount for Glock 43X/48 MOS
This optic is engineered for a direct mount onto the Glock 43X MOS and Glock 48 MOS slides. This eliminates the need for adapter plates, providing a streamlined installation and a more secure fit for your carry firearm.
Extended Battery Life and Shake Awake
With a claimed 50,000 hours of battery life and Shake Awake technology, this red dot is designed for long-term readiness. The optic automatically powers on when it detects motion and conserves power when idle, ensuring it’s ready when you need it.
Shockproof and Waterproof Durability
The C+H EDC is built to withstand the demands of daily carry, featuring shockproof and waterproof construction. This ensures reliable performance in various environmental conditions and during rigorous training sessions.
Adjustable Brightness Settings

Buyer’s Guide
When selecting the best glock 43 red dot, several key factors will ensure you get an optic that’s reliable, durable, and suited for your specific needs.
Footprint Compatibility
The most critical factor is the optic’s footprint, which dictates how it mounts to your slide. For the Glock 43X MOS and 48 MOS, you’ll primarily be looking for sights with an RMSc footprint. Some optics may come with adapter plates for different slide cuts, like the Glock MOS system, which can add height or complexity.
Durability and Construction
For a concealed carry pistol, durability is paramount. Look for optics constructed from robust materials like 7075-T6 aluminum, with good shock resistance and water/dustproofing ratings (e.g., IP67 or higher). These sights need to withstand recoil and the daily wear and tear of being carried.
Battery Life and Activation
A long battery life (often 20,000-50,000 hours) is essential for a carry optic. Features like Shake Awake technology, which automatically turns the optic on when motion is detected, are incredibly convenient and conserve power, ensuring your dot is ready when you draw.
Reticle and Brightness
Consider the reticle size (e.g., 3 MOA dot) and whether you prefer a simple dot or a more complex reticle like a circle-dot. Ensure the optic has sufficient brightness settings, including a daylight-visible mode, to be effective in all lighting conditions.
Integrated Sights
Some optics, like the Triton Nautilus2, feature integrated backup iron sights. This is a significant advantage for defensive firearms, providing a reliable sighting solution even if the electronic dot fails or the battery dies.
Who Should Buy What
For those prioritizing integrated backup sights, the Triton Nautilus2 is a strong contender. If you need an adapter plate for a Glock MOS slide and appreciate reticle versatility, the ARORY RMU1 is a good choice. For a straightforward, direct-mount option specifically for Glock 43X/48 MOS, the C+H EDC is worth considering.
What To Avoid
Avoid optics with proprietary mounting systems that require special plates or adapters unless absolutely necessary. Also, be wary of brands with unclear recoil-testing procedures or those that don’t specify their materials and water/dust resistance ratings, as these are often indicators of lower durability.
How These Products Compare
While all these optics target the Glock 43X MOS and similar pistols, they differ in features like integrated sights, reticle options, and whether an adapter plate is included. The Triton stands out with its built-in irons, while the ARORY offers reticle choice and the C+H provides a simple direct mount.
Frequently Asked Questions
Do I need an adapter plate for a red dot on a Glock 43X MOS?
The Glock 43X MOS typically comes with a slide cut for the RMSc footprint. Therefore, most optics designed for this footprint will mount directly without an adapter plate. However, if you have a standard Glock 43X slide or an optic with a different footprint, you might need an adapter plate or a different slide cut.
What is the best red dot size for a Glock 43X?
For a Glock 43X, a 3 MOA dot is generally considered ideal. It offers a good balance between a precise aiming point for accuracy and a visible dot for fast acquisition. Some users prefer a 6 MOA dot for even faster target acquisition in close-quarters scenarios.
Can I use a red dot sight for concealed carry?
Absolutely. Red dot sights can significantly improve target acquisition speed and accuracy, which are crucial for self-defense. When choosing for concealed carry, prioritize durability, a slim profile, and reliable battery life, like those found on the Triton Nautilus2 or C+H EDC.
How do I maintain a red dot sight on my Glock 43X?
Regular maintenance involves keeping the lens clean, checking the battery periodically (even with long life claims), and ensuring the optic remains securely mounted. Features like Shake Awake and side-load batteries simplify this process, as seen on the ARORY RMU1.
