The Sig P365 is an amazing little handgun…
It was a groundbreaking pistol when it was first introduced because the capacity just blew away (pun intended haha) the competition…
And even though there are similar guns now, like the Springfield Hellcat and Glock 43x, the P365 remains a top-tier concealed carry choice…
Additionally, it has become very popular to add an optic onto your concealed carry gun nowadays…
This is something that makes a lot of sense because adding a red dot to your handgun allows you to shoot faster and more accurately…
And since you can get the P365, the P365X, and the P365XL in optics-ready versions, it’s not a big hassle to get a red dot mounted onto your gun…
Now with all of that in mind, you might be wondering what the best Sig P365 red dot is, and in this post, I’m going to answer that question for you…
I’ll be doing that by giving you my list of the Top 8 Best Sig P365 red dots that are currently on the market…
And in the end, you’ll have a really solid understanding of the options that are out there right now, and you should be able to determine which red dot is going to work best for you…
Let’s get started!
Best Sig P365 Red Dot – Top 8 List…
The best Sig P365 red dot is the Holosun 507K. It’s the best because it’s very rugged and reliable, and it also has extremely long battery life, 3 reticle choices, Shake Awake technology, and it has a footprint that is compatible with all optics ready versions of the Sig P365…
Below I’ll give you more detail why I think the 507K is the best red dot for the Sig P365, and I’ll also give you 7 more amazing options that you can consider…
1. Holosun HS507K-X2 (My #1 Pick!)
As I said earlier, I think the Holosun 507K is the best red dot for the Sig P365 and there are several reasons why. First of all, the 507K is an extremely durable and reliable little optic. It has a sight housing that’s made from 7075-T6 aluminum, and the square top design makes it fairly impact-resistant as well…
It’s also waterproof in up to 1 meter of water, and it’s developed a reputation over the past few years, of being an incredibly strong little sight. In addition to that, the 507K comes with Holosun’s Multiple Reticle System which means you get 3 reticle choices in your sight. The 3 reticle choices are a 2 MOA dot, a 32 MOA circle, and the Holosun Circle Dot Reticle which is my favorite because it helps you shoot really fast and accurately…
The Holosun 507K also has ultra-long battery life at around 50,000 hours (5 years!), Shake Awake Technology (which will help you save battery life), and a side-loading battery tray that makes battery changes fast and easy. On top of that, because this is the X2 version of the 507K, you can lock out the brightness adjustment buttons, so that your brightness doesn’t go way up or way down while you’re concealed carrying your P365 throughout the day…
Last, the Holosun 507K features a proprietary footprint that is compatible with the optics-ready versions of the P365 without any mounting plates or modifications that you have to make to the slide. This is awesome because it means you’ll be ready to mount the optic onto your P365 as soon as you receive it, and you won’t have any hassle getting it on there…
So in the end, I think the Holosun 507K is the best red dot for the P365 because it’s very strong and reliable, it has super long battery life, it has the circle dot reticle (which helps you shoot faster), and it can easily be mounted onto your gun without any adapter plates or permanent slide modifications!

2. Trijicon RMRcc
Number 2 on this list of amazing red dot sights for the Sig P365 is the Trijicon RMRcc. Now, the Trijicon RMR is by far the most popular handgun red dot when it comes to full size or even double-stack, compact pistols (like the Sig P320), but Trijicon actually makes a smaller version of the RMR called the RMRcc (or ‘concealed carry’) which fits on single stack/ slimline handguns…
And there are many reasons why the RMRcc is a wonderful little optic for the P365. For starters, the Trijicon RMRcc is probably the toughest little red dot in its size and class. It has a sight housing that’s made from 7075 aluminum, and it features Trijicon’s patented square top (with horns) shape which is designed to make the sight incredibly impact-resistant. In addition to that, the RMRcc is waterproof in up to 66 feet of water, and Trijicon is well known for making super rugged optics that are used in the military and in law enforcement…
On top of that, the RMRcc comes in two versions, the 3.25 MOA dot reticle version and the 6.5 MOA dot reticle version. I prefer the 3.25 MOA dot version because the dot is very easy for your eye to pick up (so you can shoot fast), but it’s also small enough that it allows you to aim precisely at small targets or targets that are at distance…
The RMRcc also has around 4 years worth of battery life, and it has a total of 8 brightness settings which includes an extra bright setting and 2 night vision settings that you can use if you night vision equipment…
The one downside when it comes to mounting the Trijicon RMRcc on the Sig P365 is that you will need an adapter plate due to the unique footprint of the RMRcc. That being said, an adapter plate is a pretty easy part to get, and if you need help finding one, I recommend you check out this one…
In the end, just like its big brother the RMR, the Trijicon RMRcc is an amazing little optic, and all you need to get it mounted onto your Sig P365 is an adapter plate.

3. Shield RMSc
Another fantastic red dot that you should consider for your Sig P365 is the Shield RMSc. Shield was one of the first manufacturers to come out with an optic that can fit on the small, slimline concealed carry guns (like the P365) that are popular today, and the RMSc is a fantastic little red dot for many reasons…
To begin, even though the Shield RMSc is not as tough as the Holosun 507K, it’s still a fairly durable little optic. It has a sight housing that’s made from aerospace grade aluminum, and depending on how you like to balance durability with lens clarity, you can get the RMSc with a polymer lens or a glass lens…
In addition to that, you can get the RMSc with either a 4 MOA dot reticle or an 8 MOA dot reticle. Out of the 2, I prefer the 4 MOA dot reticle because it’s very easy to track the dot, and it’s a smaller dot that gives you more precision when you’re aiming…
The battery life that you get with the RMSc is also very good and can last for around 4 years, and the brightness adjustments are done automatically within the sight depending on the ambient lighting conditions. I personally prefer manual adjustments on my red dots because I like to have a little bit more control, but optics that have automatic adjustments are becoming more and more popular, and there are many shooters who prefer that feature…
Last, the RMSc is a great fit for the Sig P365 because much like with the Holosun 507K, it mounts directly onto the optics ready varients of the P365 without the need for an adapter plate or slide modifications. So all in all, the Shield RMSc is another fantastic red dot option for the Sig P365 because it’s fairly rugged, it’s reliable, and it can be easily mounted on the P365’s slide.

4. Swampfox Sentinel
Another red dot that you should consider for your P365 is the Swampfox Sentinel. Much like Holosun did a few years back, Swampfox is starting to make a name for themselves in the optics space because they’re producing high-quality sights that are competitively priced, and the Swampfox Sentinel carries on that tradition…
To begin, the Sentinel is a decently tough red dot sight. Its sight housing is constructed from 7075 aluminum, and it’s waterproof in up to 1 meter of water. That being said, the people over at Swampfox devised a way to make the Sentinel even tougher. You can actually get a steel shield that sits around the Sentinel even when it’s mounted on your gun, and with the addition of the steel shield, the Sentinel is as tough as any other red dot on this list…
Now the reticle that you get with the Sentinel is a 3 MOA dot. I prefer reticles that fall into the 2 to 3.5 MOA dot range because they’re very easy to track, and they offer you a lot of precision when you’re aiming. And this dot obviously falls into that ‘sweet spot’ size range that I like…
The battery life on the Swampfox Sentinel is also very long at around 2 years worth, and Swampfox makes the Sentinel in a manual brightness adjustment version AND an automatic adjustment version. Out of the two options, I prefer the manual adjustment version because, like I told you before, I like to have more control over the sight…
…but like I also mentioned earlier, there are many shooters who prefer automatic brightness adjustment on their sights. So I think it’s great that Swampfox offers both options because you can get whichever option matches your individual preferences.
Last, the Swampfox Sentinel features the RMSc footprint, which has become the most common footprint for these super compact red dot sights. Because of that, you can mount it directly onto the slide of your P365 without any modifications or the need for an adapter plate.

5. Crimson Trace RAD Micro Pro
The fifth red dot on this list is a very exciting option in my opinion. The reason why is it’s a brand new design, and the early reports about this optic are that it’s a fantastic addition to that market. It is the Crimson Trace RAD Micro Pro, and there are many reasons why it would make a good pair with the Sig P365…
First of all, the RAD Micro Pro is a very rugged and reliable little red dot. Its sight housing is made from aerospace aluminum, and the square-top is specifically angled to make it extremely impact resistant. It’s also waterproof in up to 1 meter of water, and it’s shockproof and fog proof as well…
In addition to that, the reticle on the RAD Micro Pro is a 3 MOA dot which falls into the sweet spot for me because you can track it easily and aim precisely with it, and the battery life is around 10,000 hours which is certainly long enough for are serious use (because you should change out your battery at least once a year regardless of the battery life)…
On top of the battery life, the RAD Pro features a Shake to Wake feature that is similar to that found on the Holosun 507K, and this is a cool feature because it will help you save battery life by conserving energy when your sight is not being used…
Last, like many other sights on this list, the RAD Micro Pro features the RMSc footprint, and that means that you can easily mount it onto the slide of an optics ready Sig P365 without the need for an adapter plate or any permanent slide modifications. So all in all, I think this sight has a lot to offer (especially considering its affordable price point), and I think it’s going to become a very popular mini red dot sight.

6. Holosun HS407K-X2
Ok, so my number 1 pick on this list was the Holosun 507K (I love Holosun red dots because they’re packed with features AND affordable!), but let me tell you how the Holosun 407K is different, and why it would make a great red dot for the Sig P365. First of all, the Holosun 407K is built to be just as rugged and reliable as the Holosun 507K…
It features a sight housing that is made from 7075 T6 aluminum, and it also has the square top that Holosun has found (in their testing) to be more durable than round top red dot sights. It’s also waterproof in up to one meter of water, and it’s shockproof and fog proof as well…
The major difference between the 407K and the 507K is that the 407K has a 6 MOA dot reticle, and because of that, it’s set at a lower price point than the 507K. Now, I do prefer the reticle options on the 507K because I like the 2 MOA dot reticle better than a 6 MOA dot, and the Circle Dot Reticle is my favorite reticle on a red dot sight because of how fast and accurately you can shoot with it. But those are my personal preferences, and there are a lot of shooters who specifically like a 6 MOA dot reticle on their handgun optics (they usually find it very easy to track)…
Now, the 407K also has around 50,000 hours of battery life (5 years worth), Shake Awake technology (which will help you save battery life), and a side-loading battery tray which will make battery changes fast, easy, and convenient…
And it also features the same footprint as the 507K which will allow you to mount the 407K directly onto the slide of your optics ready P365 without the need for an adapter plate or any slide modifications. So really, if you like the 507K, but are happy with a 6 MOA reticle rather than Holosun’s Multiple Reticle System AND you want to save a little bit of money, the Holosun 407K might be the right red dot for you!

7. Hex Wasp
Number 7 on this list of the best red dots for the Sig P365 is the Hex Wasp. Now, truth be told, the Hex Wasp was designed by Springfield Armory to work with the P365’s biggest competitor, the Springfield Hellcat. But the Wasp is a fantastic little red dot, and there are many reasons why it will work well with the P365…
First of all, the Hex Wasp is a fairly rugged and reliable red dot sight. The sight housing is made from 6061 T6 aluminum, and it’s waterproof in up to 1 meter of water. It’s not as tough as the Holosun 507K or the Trijicon RMRcc, but I think it’s plenty durable for the role of concealed carry…
In addition to that, the Wasp features a 3.5 MOA dot reticle, which is right in the sweet spot that I prefer, and the lens is fairly clear and scratch-resistant. The battery life is also very good at around 2 years worth, and the brightness adjustments are done automatically by the sight depending on the ambient lighting condition in which you find yourself (I personally prefer manual adjustment settings, but the auto adjustments on the Wasp are pretty good)…
Last, like the Swampfox Sentinel, the Wasp features the RMSc footprint, which means that you can easily mount it onto the P365’s slide without any adapter plates or slide modifications. So even though it’s designed to work with the Hellcat, the Hex Wasp is a reliable red dot with good battery life that will fit onto the Sig P365 without any hassles.

8. Sig Romeo Zero
The last sight on this list is the red dot that is built by Sig to work with the P365, and that is the Sig ROMEOZero. This is a unique red dot because the sight housing is made from polymer. And let me get this out of the way… because this sight is made from polymer it is not going to be as durable as those that are made from aluminum…
That being said, I do think the ROMEOZero is tough enough to handle concealed carry use, and there are some scenarios in which the flex in the polymer might handle impact better than a harder material like aluminum. Now, you can get the Romeo Zero in a version that comes with a 3 MOA dot reticle or in a version that comes with a 6 MOA dot reticle. You know by now that, I prefer the 3 MOA dot version because it falls within my sweet spot for tracking and speed shooting, but the 6 MOA dot option is there if it fits your shooting preferences…
The battery life that you get with the Romeo Zero is very long at around 20,000 hours worth, and just as with other Sig red dots like the Romeo5, it features Sig’s MOTAC System, which is really cool because the sight will automatically turn off when it’s not being used and automatically turn on when it senses motion (this saves you a lot of battery life)…
Finally, the Romero Zero features the RMSc footprint, and of course, because it’s a Sig red dot, it is designed to be mounted on the Sig P365 without the need for an adapter plate or slide modification. So all in all, if you can get over the fact that the Romeo Zero is a polymer red dot, it has a lot of cool features and is designed by Sig to work with the P365 platform.
