Top 4 SIG P365 Red Dot Sights [2021]
source: Maple Leaf Firearms
The SIG Sauer P365 is one of the best everyday concealed carry pistols, there’s no doubt about that. The pistol is very compact, lightweight, easy to conceal, and it offers very high capacity for such a small gun. On top of all these features, the P365 is also a highly accurate pistol, mainly thanks to the SIG Sauer XRay3 Night Sights the pistol comes with. Do you want to find out more about what this excellent micro-compact pistol has got to offer? Then read our full SIG Sauer P365 review here.
If you want to move your P365 accuracy game a bit further, though, you can get one of these tactical lights and lasers. But there’s one more way to increase your SIG’s accuracy and target acquisition. You can get yourself a brand new SIG P365 red dot sight.
Step 1 — SIG Sauer P365 Red Dot Adapter
As the SIG P365 is not an optics ready gun (unlike the SIG P365 XL and SIG P365 SAS), you’ll first have to get a P365 red dot adapter before you buy your go-to red dot sight. But don’t worry, you don’t have to spend ages browsing the web for the best red dot adapter mount for your SIG P365. As I want you to save a bit of your time, I did the research, and this SIG P365 red dot adapter mount by Outer Impact seems like the best one out there.

The best SIG p365 red dot sights
Have you already added the red dot adapter mount to your cart? Excellent! Your SIG P365 is optics ready now and you can start searching for the best red dot sight for your pistol. However, how to pick the best available optics is a difficult question to answer.There are many factors you need to consider when ranking red dot and reflex sights. I’d say the most important factors you shoul consider are:
- Durability of material
- Quality of the lens
- Resistance level
- Compatibility and mount style
- Windage and elevation adjustability (almost all red dot sights feature this)
- Battery life
- Red dot size or MOA
I’m sure you’re asking yourself: “What on earth is MOA?” Well, in layman’s terms, the more MOA a particular red dot sight offers, the easier it is to acquire a target, as the dot is bigger. On the other hand, the smaller the dot, or the lower the MOA is, the more precise your aim is.
Well, now that you know almost everything about red dot sights, let’s have a look at our list of Top 4 SIG P365 Red Dot Sights. And I’m sure you’ll find your favorite among it.

Prices accurate at time of writing
Now the first red dot sight for our SIG inevitable has to be the one from production of SIG Sauer itself. Their Romeo Zero red dot sight has recently become one of the most popular P365 red dot and reflex sights, and rightfully so.
Apart from being made specifically for the P365 XL (as the pistol is optics ready) and compatible with the regular P365 (if you get the above mentioned adapter), you know there’s not many more ideal options for your SIG. It boasts 3 MOA, which is quite a lot, especially if you realise how extremely small, compact, and light this optics device is. On top of that, it’s SIGnificantly cheaper than other SIG P365 red dots.
Features & Benefits
- Material — Ruggedized Weapons grade polymer
- Dot size — 3 MOA
- Batteries used — 1x CR1632 Battery
- Installation — Compatible with all SIG P365 models
- Special features — super compact and lightweight
Pros
- An official SIG Sauer product
- Quite inexpensive
- Very light and compact
Cons

№2 — TRIJICON RED DOT SIGHT
TRIJICON RMR TYPE 2 6.5 MOA ADJUSTABLE LED RED DOT SIGHT
From $584.89

This SIG P365 red dot sight is an ultimate optics solution. The RMR abbreviation in the product name stands for “ruggedized miniature reflex”, which means it’s strongly built and capable of withstanding even the roughest handling. Now how does it perform? The answer is simple — according to Trijicon standards, which means excellently. It features an automatic brightness mode and lets you select between eight different brightness settings. These include also 2 different night vision modes and 1 super bright mode.
One drawback could be that the price tag on this one is much higher than the TruGlo red dot sight mentioned before, but I think it’s a reasonable price for such a high-end product. BTW, did I mention that it’s waterproof up to 66 feet for nearly an hour?
Features & Benefits
- Material — Military-grade aluminum alloy
- Dot size — 6.5 MOA
- Batteries used — 1x CR2032 Battery
- Installation — Any gun with a milled gun slide
- Special features — night vision, waterproofness
Pros
- Extremely durable and waterproof
- Supports night vision
Cons
- Smaller viewing window
- Price tag

This SIG P365 red dot sight by Leupold is slightly heavier than the first one, but it’s a favorite choice as the glass it features is extremely clear and offers a large view. How come? It features a DiamondCoat aspheric lens, which increases the field of view by more than 50% and it’s also scratch resistant. It’s equipped with a motion-sensing auto-on function, so you’ll be ready to place your sights on your target as soon as (or even sooner!) draw your SIG.
A great feature of this pistol red dot sight is the battery loading from top, so you can easily replace the battery without having to remove it. Compared to the one by Trijicon, it’s not night vision compatible, but as long as you won’t be lurking out in the dark much, you should be just fine and this Leupold red dot sight is one of the best options for you.
Features & Benefits
- Material — Rugged aluminum
- Dot size — 2.5 MOA
- Batteries used — 1x CR2032
- Battery Installation — Picatinny rail or Glock MOS system
- Special features — Motion-sensing auto-on function
Pros
- Crystal clear lens + enhanced field of view
- Top loaded batteries
Cons
- Battery life
- Not night vision compatible

This would be one of my favorites if I was searching for a new red dot sight for my SIG Sauer P365. Why? Well, it’s claimed to be (and I believe it is) one of the lowest profiled red dots out there. Viper features extremely durable anodized finish and it’s also waterproof and shock resistant, which means you don’t have to waste time checking out the weather forecast before using it.
Now talking about it’s performance, it’s one of the best pistol red dot sights in this price range (you can’t expect it to outperform the most expensive sights, but, hey, someone’s got to pay the bills). So, guys, if you want to avoid spending ages going through the vortex of pistol red dot sights out there, go for Viper by Vortex.
Features & Benefits
- Material — Hard anodized finish
- Dot size — 6 MOA
- Batteries used — 1x CR2032 Lithium Battery
- Installation — Weaver/Picatinny mount
- Special features — Extra low profile
Pros
- Extremely low-profile and lightweight
- Durable construction and lens
- Very budget friendly
Cons

DO I NEED A RED DOT for my sig P365?
You might be asking yourself, if you really need a red dot sight for your SIG. I’ll leave that up to you, but here’s a couple of benefits of red dot sights that might talk you into getting your first SIG P365 red dot sight:
- Fast target acquisition
- Long range shooting
- Low-light environment shooting
- Increasing your awareness
- Improving your aim despite poorer eyesight
- Better performance of your handgun in tactical situation
Putting a red dot sight on your SIG doesn’t mean you are putting on rose-colored glasses, though. Obviously there are also some issues that come hand in hand with the benefits:
- Electronics reliability (check out the remaining battery life every now and then)
- It takes some practice getting used to red dots
- They can get quite expensive
- Weather could be an issue (especially extreme conditions)
Conclusion
If you’re contemplating upgrading the optics and accuracy of your SIG P365, getting a decent red dot sight is a very good idea. However, don’t forget you’ll first have to get a decent red dot adapter mount as the pistol itself isn’t optics ready. And, most importantly, keep in mind that you will be able to enjoy your pistol to the fullest only if you get a well-fitting SIG Sauer P365 holster.
