Best Optics For Glock MOS – Locking Right In!

Who doesn’t love some Glocks in their life? I feel like almost every security enforcer and most self-defense arms holders owns at least one Glock in their arsenal.

While regular Glock can feature a cutout for specific optics, MOS is a system that allows you to slide in a lot of different optics. MOS stands for modular optic system.

If you own one and looking for the best optics for your Glock MOS, you have come to the right place! Without further ado, let’s get right into it.

Best Glock MOS Optics – [Editor’s Choice]

1. Leupold DeltaPoint Pro Reflex Sight

The best looking red dot sight award goes to, wait a minute! We are not here to rank sights based on their looks! Jokes aside, this is one of the best-looking red dot sights you will find! From the design to the texture of the actual product, it looks awesome.

The sight is made out of aluminum and it’s a reflex sight. This means you get unlimited eye relief and you can shoot through the sight from any angle you want to. In terms of anodization, the QC is top tier. You will not find any visible artifacts present in the optic.

The lens of the sight is fully multi-coated as well. What makes the lens even better is the technology Leupold includes in their sights. It’s called the twilight light management system. On this sight, they call it the Leupold Twilight Red Dot management system.

What it does is, it makes the red dot brighter in low-light conditions and makes it perform way better than any red dot in this price range has to offer.

Pairing this with a Glock MOS is quite easy. It takes the sight quite well. The synergy is there and the performance boost is noticeable.

Key Features

  • USA! Leupold designs and manufactures all of its sights in the USA! You will get prompt response on warranty and fast customer service at any given time!
  • Easy to swap battery! A lot of sight comes with systems that make it hard to change the battery, not this one!
  • Easy to mount! Leupold might even call it Loki as it’s a shapeshifter! What I mean is, that you can use different mounting plates to install this on different gun slides!

2. HOLOSUN HE509T 2 MOA Red Dot Sight

HE509T looks like a holographic sight. But it’s a red dot that comes with a 2MOA red dot reticle. Instead of going for traditional aluminum to make the sight. Holosun used something different on this sight.

Don’t worry, it’s still not polymer. But it’s made out of titanium. A lightweight, premium, and durable material that you don’t often see in sight because of how crazy expensive the material is.

Holosun managed to make a sight that doesn’t cost a lot of money and still offers titanium rugged construction. The 2MOA red dot reticle is illuminated.

You can see the reticle clearly in low-lighting conditions as well. The best part about this illumination is, you got 2 adjustable levels for nighttime as well. Almost all Holosun sight packs this feature and I can’t recommend this feature enough.

It’s a lifesaver for folks who are using the sight on a small gun like Glock 19 MOS. You can use this sight as a canted sight on rifles as well. And you get the idea of what it could be in the night with a rifle.

Without a doubt, the Holosun HE509T is one of the best optics for Glock MOS. One might say, it’s one of the best red dot sights in general.

Key Features

  • RMR! This optic comes packed with an RMR adapter inside the box. That’s quite generous when you find most sights do not come with anything.
  • Battery for days! HE509T-RD uses a single CR1642 battery and it can last you years to come!
  • Shake Shake! It features a shake-to-wake sensor that activates when it detects some movement.

3. Vortex Optics Venom Red Dot Sight

If you are looking for a killer red dot sight to pair with your Glock MOS and are not willing to spend a fortune on it, the Vortex Venom red dot sight should be at the top of your priority list.

This red dot sight from Vortex is extremely tiny and lightweight. The performance of this sight is not tiny, however.

The build quality of this optic is quite nice. It’s a well-built sight with tons of features offered to self-defense and tactical shooters alike.

The lens of the sight is also coated multiple times to make it useable in bright daylight and low-light conditions. You can easily defend yourself or target practice during the evening as well.

The reticle is large and bright enough to use during the night as well it’s nowhere near enough to replace your night vision device.

Key Features

  • South-East Asia Express! This optic is manufactured in the Philippines and then later quality-checked multiple times here in the USA. So, you are essentially getting a multiple-stage QC-checked optic for your Glock.
  • Mounting Galore! You can mount this optic on many things including your Glock. You can use this on a rifle and a riflescope to use as a canted sight, the limit is your imagination.
  • Generous Battery: Using a CR1632 battery, you can expect two or more years of illuminated reticle out of it.

4. Burris FastFire III Red Dot Sight

FastFire 3 is the 3rd generation sight from the Burris FastFire lineup. It has improved on a lot of things over the past iteration and made the sight even better. The sight is durable, rugged, and solid made

The sight has a construction that you can use to break something. Ha-ha! Don’t do that. But it is a pretty strong sight. It can withstand any kind of military environment torture with ease.

The lens of the sight is pretty durable and bright as well. Fully multi-coating makes the lens perform way better than it is.

You won’t have any issues using this sight for all sorts of activities that you want to do with your Glock MOS. Glock’s fire rate is exceptionally high for a handgun. When you are buying a sight for Glock MOS, you need to make sure the sight can keep up with that fire rate and recoil.

Luckily for you, this sight is more than capable of handling a Glock. If you want to upgrade to a rifle down the line, you can use this sight on that rifle as well. As Burris provides a decent amount of warranty, you don’t need to worry about that much.

Key Features

  • Burris Masterclass! Burris is known for their American-designed and in-house manufactured optics. The FastFire III is no exception. It’s a Burris masterclass!
  • Never run out of battery! Well, technically battery will run out. But you can use this for a few years before that event comes into place.
  • Glock Compatible! Yes, it fits on the Glock with quite ease! No gunsmith is required, implying you know how to dismantle a Glock slide.

5. Sig Sauer RomeoZero 1x24mm Red Dot

Sig Sauer makes great guns and their optics are equally awesome. While they are mostly popular with rifle owners with their Romeo 5, their Romeo Zero is also quite beloved by the community for its affordable price tag and incredible performance.

This optic is not made out of aluminum nor does it feature any glass-made lens. Instead, it features a Polymer lens with hardened texture and incredible clarity. it also has a WeaponsGrade textured polymer body. It’s the same type of polymer that you find in your guns.

In short, the build quality is nothing to slack about, it’s simply amazing! I know I always recommend aluminum and titanium optics, but for Romeo Zero, I can make an exception! The 24mm lens is extremely clean and the LED emitter inside provides a crisp dot that is more clear than other similarly priced optics.

Following the RMS-C footprint and J-Point footprint, this is an ideal choice for polymer concealed-carries like the Glock!

Key Features

  • Unlimited Power! Well, not entirely. But Sig Sauer does provide a limited lifetime warranty with this optic.
  • A mixture of cultures: While Sig does manufacture this optic in their factory, some of the parts are imported.
  • Easy to use: The ease of access of this optic is top-tier. Not only the price is beginner-friendly, but the operating procedure is also simple.

Things To Keep in Mind Before Buying

Glock isn’t like our traditional pistols. It’s very picky about sights and often sight fails due to how a Glock operates. Finding the best sight for Glock can be a handy task. Don’t worry, you can make it quite easier if you follow a couple of steps.


A Glock is a lightweight gun. The weight is fairly balanced. However, you don’t want the gun to be heavy towards the back. It will make you lose focus on the second shot due to the recoil balance.

If you don’t want that to happen, make sure to take a sight that is lightweight in general.

Overall Quality

This includes both build quality and lens quality. Make sure to take a durable sight with a good lens. A good lens goes a long way. Just like you are picky about what lenses to pick up for your glasses, be picky about what lenses the sight has to offer.

That will help you choose the best one for you with ease.


Optics are small items. We don’t want to visit the doctor every day to get fixed something. But having insurance sure comes in handy.

Just like that, having a warranty will come in super clutch as well.


Another important factor in your decision-making is the budget. If you know how much you are willing to spend, then you can easily pick up the best Glock red dot for your usage!


This took longer than I anticipated. But hey! We discussed some sights, you took a sip of your coffee, win-win scenario in my books.

Jokes aside, I hope you found the sight you have been looking for. And if you are struggling to decide the best red dot for Glock MOS, I hope this was able to help you pull the trigger on that sight.

That’s all for now, will be back with more for you guys soon. C’ya.
