You can’t go wrong with a Glock…
It’s such an iconic handgun design, and it’s proven itself to be simple, reliable, and easy to shoot over the span of several years now…
And with the introduction of the Glock 43X MOS, Glock has given us consumers a ‘high capacity’ slimline gun, that’s optic ready and that can easily be used for concealed carry…
But what is the best Glock 43X MOS red dot that you can get? What optics can you actually put on your 43X?
Well in this article, I’m going to share with you the 7 best red dot sights that you can mount on your Glock 43X MOS…
And by the end, you’ll know exactly what options are out there, and you should have all the information you need to determine which optic is going to work best for you…
Let’s begin!
Glock 43X MOS Red Dot – Top 7 List…
The best Glock 43X MOS red dot is the Holosun 507K X2. It’s the best because it’s a rugged and reliable optic. In addition to that, it’s packed with useful features (like 3 reticle options and ultra-long battery life), and it’s also fairly affordable. The only downside is that you will need an adapter plate to mount it on the Glock 43X MOS…
The following will give you more detail discussing why the Holosun 507K is the best optic for the Glock 43X…
And I’ll also share with you 6 other fantastic red dots that’ll pair well with this amazing little Glock…
1. Holosun HS507K-X2 (My #1 Pick!)
Let me tell you a little story… There once was a guy who lived in Las Vegas. He carried a Glock 19 during the winter and a Glock 43X during the summer. On his Glock 19, he mounted a Holosun 507C, and on his Glock 43X he mounted a Holosun 507K X2…
Why am I telling you this? Because that guy is me! I conceal carry a Glock 43X, I mounted a Holosun 507K on it, And I love it! So my first recommendation to you is the red dot that I’ve chosen to put on my personal 43X…
No here’s why I think the 507K is the best red dot for the Glock 43X, the Glock 48, the Springfield Hellcat, the Sig P365, the M&P Shield, the Canik TP9 SC, and basically all other slimline, concealed carry handguns. First of all, the 507K is built to be very rugged and reliable. The sight housing is made from 7075-T6 Aluminum, and it has a square-top design which has been proven to make the sight more robust if it gets dropped on the ground or heavily impacted…
The 507K also has Holosun’s Multiple Reticle System which means that you can switch between 3 reticle choices including, a 2 MOA dot, a 32 MOA circle, and the Holosun Circle Dot (which is my favorite because it helps you shoot fast and accurately). On top of that, the 507K has super long battery life (around 50,000 hours on setting 6), Shake Awake technology (which saves you a ton of battery life), and the battery can be changed without having to remove the optic from your 43X’s slide (which is incredibly annoying)…
You also get a back up rear sight that is built into the 507K’s sight housing, and because it’s the X2 version, you can lock all the buttons which will prevent you from accidentally turning your reticle brightness way up or way down while you’re concealed carrying. The only downside is that the Glock 43 MOS comes with an optic cut for the RMSc, and the 507K footprint is a little bit different. There are ways you can modify your slide, but the easier method for mounting a 507K on your Glock 43X MOS is to simply get an adapter plate (you can get one right here)…
So all in all, I highly recommend the Holosun 507K. It’s what I own and use on my Glock 43X, and it’s been fantastic.

2. Shield RMSc
The Shield RMSc is also a great red dot for the Glock 43X. As I mentioned above, the Glock 43X MOS comes with a slide that is cut for the RMSc footprint. And that footprint has become the most common footprint in this new super small sized optic class. So the Shield RMSc (the ‘c’ stands for compact) will fit perfectly on top of the Glock 43X MOS slide without the need for an adapter plate…
On top of that, the Shield RMSc is a pretty rugged little sight. It’s not as rugged as the Holosun 507K or some of the other options that I’ll show you on this list, but as you can see when you look at the picture, it has those distinctive support rails along both sides of the housing which add strength and rigidity to the optic. And they make this sight plenty durable enough for concealed carry…
Also, the Shield RMSc is a ‘permanently on’ optic. So it will automatically adjust to the ambient lighting conditions that you’re shooting in, and you can also get it in a few different versions. For example, you can get the RMSc with a 4 MOA (minute of angle) dot reticle or an 8 MOA dot reticle (4 would be my preference because it gives you more precision when aiming). And you can also get it with a polymer lens or a glass lens depending on how you personally want to balance lens strength against lens clarity.

3. Crimson Trace RAD Micro Pro
Another very exciting red dot that will pair perfectly with the Glock 43X MOS is the Crimson Trace RAD Micro Pro. At the time I’m writing this, the RAD Micro Pro is a brand new optic being offered by Crimson Trace, and I think its an extremely exciting little red dot for several reasons…
First of all, the RAD Micro Pro is built to be very durable and reliable. It’s made from Aerospace aluminum, and it has a squared-off top that also has built-in angles to make it more impact-resistant. It also has large, easy-to-use brightness buttons on the side of the sight housing, and I personally think it looks really cool…
On top of that, the RAD Micro Pro has very long battery life (around 10,000 hours), and it features a 3 MOA dot reticle which I like because I find that dots in the 2-3.5 MOA size range offer more precision when I’m aiming. The RAD Micro Pro is also waterproof, shockproof, and fogproof, and it also features the RMSc footprint. So you can mount it directly on your Glock 43X MOS slide without the need for an adapter plate.

4. Swampfox Sentinel
The Swampfox Sentinel is another great red dot that you should consider for your Glock 43X. To start off with, this little red dot also features the RMSc footprint. So just as with the Shield RMSc and the Crimson Trace RAD Micro Pro, you can mount it directly onto your 43X MOS slide without any modification or the need for an adapter plate…
Aside from that, the Sentinal is built to a high standard which makes it reliable, and it’s also fairly durable. Now, it’s not as durable as the Holosun 507K, but I think it’s certainly durable enough for concealed carry. And if you have any concerns about the durability, you can actually get a steel cover that goes around the Sentinel while it’s mounted on your gun…
The Sentinal also comes with a 3 MOA dot reticle, which as I mentioned earlier is a size I personally like for precision when aiming, and the battery life is ultra-long as well (you can actually keep this optic turned on for 2 years if you want to)…
Last, the Sentinel comes in two versions, an automatic brightness adjustment version, and a manual brightness adjustment version. I personally prefer manual brightness adjustment on my red dot sights because it just gives you a bit more control over your optic setup in general, but a lot of people really enjoy the automatic brightness technology that the Sentinel features as well.

5. Hex Wasp
Another fantastic little red dot that you can mount on your Glock 43X MOS is the Hex Wasp. Now the Wasp is actually designed to go with one of the Glock 43X’s chief rivals, the Springfield Hellcat. But it does feature a Shield RMSc footprint and can easily be mounted directly onto the 43X MOS slide without an adapter plate…
The Wasp is also a very well-built and rugged little red dot. Its sight housing is made from 6061-T6 Aluminum, and it has an anodized finish which will help protect the optic from moisture and the elements. It also has a very clear lens, around 2 years’ worth of battery life, and a 3.5 MOA dot reticle which is right in my personal sweet spot in terms of reticle size.
Last, like the Shield RMSc, the Hex Wasp is a ‘permanently on’ optic, and it will automatically adjust the reticle brightness level to the ambient lighting conditions that you’re shooting in. Now like I said earlier, I prefer manual brightness adjustment, but that’s a personal preference I have and there are many others who like the simplicity of automatic brightness adjustment technology. If you fall into the latter group, the Hex Wasp might be the right optic for you.

6. Holosun HS407K-X2
If you’ve followed my blog at all, it’s no secret that I’m a Holosun fanboy. So of course, I had to put a second Holosun on this list, but let me explain how the Holosun 407K differs from the 507K, and why you might want to consider it…
First of all, the Holosun 407K is very rugged and reliable. It’s built in the exact same manner as the 507K, and it features the same squared-off top, which as I said before, adds a lot of durability. It also has ultra long battery life of around 50,000 hours (on settings 6), Shake Awake technology, and a battery tray making battery changes quick and easy without the need to remove the optic from your handgun slide…
It’s also an X2 version, so you can lock out the brightness buttons while you’re concealed carrying it on your gun, and the footprint is the same as the 507K. So you will need an adapter plate if you want to mount it onto the Glock 43X MOS (you can get an adapter plate here).
All that being said, there are really 2 main things that differentiate the 407K from the 507K. First of all, you only get 1 reticle on the 407K and it’s a 6 MOA dot. That’s a little bigger than my personal preference, but it’s still a very useful dot size and has its own benefits (such as being a little easier to track)…
The second difference is in terms of price because the 407K is a less expensive optic than the 507K. So if you like all of the features of the 507K but you just want a 6 MOA dot reticle and want to save a little bit of money, then the Holosun 407K is definitely the optic you should go with.

7. Trijicon RMRcc
The final optic on this list of amazing red dots for the Glock 43X MOS is the Trijicon RMRcc. Now if you don’t know, Trijicon is famous for making super rugged and reliable optics. The Trijicon RMR actually sets the standard for toughness when it comes to full-sized handgun optics, and its little brother, the RMRcc (the ‘cc’ stands for ‘concealed carry’) is no slouch in that area as well…
First of all, the Trijicon RMRcc is constructed from 7075 aluminum and it features the patented RMR square-top design which is famous for being insanely tough. It’s also waterproof in up to 66 ft of water, and it’s more than strong enough to handle concealed carry service on your Glock 43X…
In addition to that, the RMRcc gives you 10 brightness settings (including two Night Vision settings), and it has ultra long battery life which can last for around 4 years. When it comes to reticle size, there are actually two versions of the RMRcc, a 3.5 MOA dot version and a 6.5 MOA dot version. Again, I prefer the 3.5 MOA dot version because of the precision it offers you when aiming, but a large dot can be a little easier to track when you’re shooting fast…
Last, like the Holosun 507K and 407K, the Trijicon RMRcc has a proprietary footprint. So to mount it onto your Glock 43X MOS you will need an adapter plate (you can get one here). But all in all, if you’re looking for the toughest possible red dot sight for your 43X, then the Trijicon RMRcc is the way to go.
