Top 5 Optic For 43X Mos Detailed Reviews
1. HOLOSUN SCS MOS Green Multi-Reticle 2 MOA Dot & 32 MOA Circle Parallax-Free Reflex Pistol Sight Compatible with Glock MOS Full-Size Handguns – Solar Charging Sight (NOT for Glock 43X MOS or 48 MOS)
Rating: 8.9/10
The HOLOSUN SCS MOS is a fantastic reflex sight designed specifically for full-size Glock MOS handguns. It attaches directly to your slide, no adapter needed. This sight uses the sun to power itself, and it can also run on its internal rechargeable battery for a very long time. It also has a special mode for super bright situations and warns you when the battery is low.
What We Like:
- The green reticle is bright and easy to see. You can choose between a 2 MOA dot, a 32 MOA circle, or both.
- It uses solar power, meaning it can potentially run forever without needing a new battery.
- The sight automatically adjusts its brightness based on the light around you, making it great for different shooting conditions.
- It’s built tough with a titanium housing and has clear, scratch-resistant lenses.
- The “intensity override” feature is useful for those times you need maximum brightness quickly.
What Could Be Improved:
- This sight is NOT compatible with Glock 43X MOS or 48 MOS models. You’ll need to look at Holosun’s “K” or “EPS Carry” optics for those.
- The automatic brightness adjustment, while generally good, might not be perfect for every single user’s preference in all situations.
Overall, the HOLOSUN SCS MOS is a high-performance sight that offers excellent value and innovative features for Glock owners. It’s a reliable choice for improving your aim and shooting experience.

Choosing the Right Optic for Your Glock 43X MOS
You have a Glock 43X MOS and want to add an optic. That’s a great idea! An optic can help you aim faster and more accurately. But with so many choices, where do you start? This guide will help you find the perfect red dot sight for your pistol.
What to Look For in a Glock 43X MOS Optic
When you’re shopping, keep these important things in mind.
Key Features to Consider
- Size and Profile: You want an optic that fits well on your 43X MOS without being too big or bulky. A smaller, sleeker optic is often best for concealed carry.
- Dot Size: Red dot sights have a dot inside. Common sizes are 3 MOA (Minute of Angle) and 6 MOA. A 3 MOA dot is smaller and good for precise shots. A 6 MOA dot is bigger and easier to see quickly.
- Brightness Settings: The optic should have adjustable brightness. You need to see the dot clearly in bright sunlight and also in dim light.
- Battery Life: No one wants their optic to die at the wrong time. Look for a sight with a long battery life. Some can last for years on a single battery.
- Durability: Your optic will take some bumps and jolts. It needs to be tough and able to handle recoil.
- Water and Fog Resistance: You might use your pistol in different weather. An optic that resists water and fog will work better.
Important Materials
The best optics use strong materials. The housing is usually made from aircraft-grade aluminum. This makes it light but very strong. The lens is often made of high-quality glass. This gives you a clear view.
What Makes an Optic Great (or Not So Great)
- Quality Construction: A well-built optic feels solid. All the parts fit together nicely.
- Clear Lens: The glass should be clear, with no distortions. This helps you see your target clearly.
- Good Dot Quality: The red dot should be crisp and round, not fuzzy or misshapen.
- Easy Controls: Adjusting brightness or turning the optic on/off should be simple and quick.
- Reliable Performance: The optic needs to hold its zero (stay sighted in) even after many shots.
User Experience and Use Cases
Think about how you’ll use your 43X MOS with an optic.
- Concealed Carry: For carrying every day, a smaller, lighter optic is better. It won’t print (show through your clothes) as much.
- Home Defense: If you use your pistol for home defense, you want something fast and easy to aim. A slightly larger dot might be helpful here.
- Range Practice: At the range, you can try different dot sizes and brightness settings to see what you like best.
A good optic makes a big difference. It helps you aim faster and be more accurate. This is true whether you’re practicing at the range or relying on your pistol for self-defense.
Frequently Asked Questions About Glock 43X MOS Optics
Q: What is the best optic for a Glock 43X MOS?
A: The “best” optic depends on your needs. Popular choices include the Shield RMSc, Holosun 507K, and Sig Sauer Romeo Zero. These are known for their size and features.
Q: Do I need a special mount for an optic on my 43X MOS?
A: The Glock 43X MOS has a “Modular Optic System” (MOS) slide. This means it has a cut for mounting optics directly. You might need specific screws or plates that come with the optic or your firearm.
Q: What does “MOA” mean?
A: MOA stands for Minute of Angle. It’s a way to measure the size of the red dot. 1 MOA at 100 yards is about 1 inch.
Q: Is a 3 MOA or 6 MOA dot better for the 43X MOS?
A: A 3 MOA dot is good for precision. A 6 MOA dot is easier to see quickly. Many people find 6 MOA works well for a concealed carry pistol like the 43X MOS.
Q: How do I install an optic on my 43X MOS?
A: You’ll typically remove the slide cover plate on your 43X MOS. Then, you’ll place the optic onto the slide and secure it with screws. Always follow the manufacturer’s instructions.
Q: Can I use any red dot sight on a 43X MOS?
A: No, not all red dots fit. The 43X MOS uses a specific footprint (mounting pattern), often called the Shield RMSc footprint. You need an optic designed for this pattern.
Q: How long does a red dot battery last?
A: Battery life varies greatly. Some can last 50,000 hours or more, while others might last a few thousand hours. Check the product specifications.
Q: Will recoil damage my optic?
A: Good quality optics are built to withstand recoil from firearms like the 43X MOS. Cheaper or poorly made ones might not.

A: Yes! Red dots make aiming much easier for beginners. You just put the dot on the target and shoot.
Q: Can I use my 43X MOS with an optic in a holster?
