And you should have all the information you need to determine which is going to work best for you…

Best Sig P320 X5 Legion Red Dot – Top 5 List…
The best Sig P320 X5 Legion red dot is the Trijicon RMR Type 2. It’s the best because it give you around 4 years of battery life, features an insanely durable sight housing (which gives you excellent reliability), and can be had in a number of different reticle sizes so you can match it to your personal preference…
Below I’ll give you more reasons why I think the RMR Type 2 is the best red dot for the P320 X5 Legion, and I’ll also share with you 4 other amazing pistol optics that you should consider.
1. Trijicon RMR Type 2 (Best Overall Pick!)
The Trijicon RMR Type 2 Adjustable LED sight is my number 1 pick for a Sig P320 X5 Legion red dot sight, and there are many reasons why. First of all, the Trijicon RMR is an insanely tough little optic…
It’s name ‘RMR’ actually stands for ‘Ruggedized Miniature Reflex Sight’ and it’s patented sqaure-top housing is designed to protect the optic lens even it if takes heavy impacts…
It’s also waterproof in up to 66 ft of water so it can easily handle rainy, snowy or any other wet conditions you can throw at it, and it’s also shockproof, with the Type 2 RMR being upgraded over the Type 1 to handle the heavy recoil of being a pistol optic…
In addition to the eight brightness settings (which include 2 NV settings), you also have several versions of the RMR that you can choose from with different reticle sizes…
That being said, the 3.25 MOA dot version and 6.5 MOA dot version are probably to two most common, and my personal preference is for the slightly more precise 3.25 MOA model just because it’ll allow you to acquire a sight picture very quickly and still give you a very fine aiming point to make accurate shots…
Furthermore, the RMR Type 2 has modified side buttons to adjust the brightness very easily, switch between manual and auto modes, or power the optic down…
On top of that, you get ultra long battery life with the RMR Type 2 as one CR2032 battery will last you for around 4 years, and the RMR is also easily mounted onto the X5 Legion with the use of an adapter plate (I like this one here)…
So all in all, the RMR is a fantastic red dot for the P320 X5 Legion because it’s insanely durable, gives you super long battery life, and can be had in a variety of different models which will allow you to get the reticle size that works best for you.
The Trijicon RMR Type 2 Features And Benefits
| Durability | The patented housing protects the lens and adds to the durability |
| Multi-coated Lens | Creates a true color with optimal light transmission |
| Dual-Illuminated Option | The Tritium-phosphor lamp is ideal for low-light conditions, and the fiber optics will auto-adjust the brightness |

2. Leupold DeltaPoint Pro
It was a really difficult call when choosing the best red dot sight for the Sig P320 X5 Legion, and honestly, the Leupold Delta Point Pro could have easily been the number 1 pick…
First of all, the DeltaPoint Pro can be mounted on to the X5 Legion without the need for an adapter plate (which is pretty cool) but in addition to that, the DeltaPoint Pro is (just like the Trijicon RMR) an extremely durable and rugged pistol red dot…
It features a strong aluminum sight housing, and the lens actually has a spring steel shroud covering it which gives you a little bit of extra protection in that vulnerable spot. It’s also waterproof in up to 33 feet of water, and it’s shockproof and fog proof as well…
The reticle that you get is either a 2.5 MOA dot or a 6 MOA dot depending on your dot size preference (I prefer the 2.5 MOA dot for a little more precision), and the 8 brightness settings make the sight highly functional in all lighting conditions…
On top of that, the sight window that comes on the DeltaPoint Pro is HUGE, which gives you a large field of view when looking through the optic and makes acquiring a sight picture super fast…
The battery life on the DeltaPoint Pro is around 300 hours for one CR2032 battery. That’s a lot less than the 4 years of battery life that you get with the Trijicon RMR, but Leupold makes up for the difference in two ways…
First of all, they include Motion Sensor Technology which means your sight will automatically turn off after 5 minutes of inactivity, and it will automatically turn on when sensing motion…
And secondly, the sight has a top access battery compartment which makes battery changes fast and easy without the need to remove the optic from your gun (which can be a hassle because you have to re-zero your sight afterward)…
So all in all, the DeltaPoint Pro is another amazing red dot option for the X5 Legion because it’s super rugged and reliable, gives you a huge sight window, and unlike the Trijicon RMR, it’s doesn’t require the use of an adapter plate to mount onto your P320 X5 Legion.
The Leupold Delta Point Pro Features And Benefits
| Red Dot Optical System | It offers light transmission for all conditions and glare reduction |
| Illuminated reticle | It helps to get on target quick in low-light conditions |
| Motion Sensor Technology | MST extends battery life by deactivating illumination when inactive for more than five minutes and activating again on a movement |
| Rugged and durable | Internal gasses and sealing methods for waterproof and fog proof |
| DPP Footprint | Designed to work with P320, M17, and M18 |

3. Trijicon SRO
Number 3 on the list is the Trijicon SRO, and I had to include this pistol red dot on the list for two main reasons. Firstly, it is a Trijicon. It’s super high-quality, and it provides an alternative option to my top pick, the Trijicon RMR Type 2…
Secondly, although it has a different sight housing design, it is still remarkably durable, and the huge sight window gives you a very expansive field of view, which is perfect because it allow you to acquire your target faster and shoot quicker…
It also features eight brightness settings, and included within those you get an extra bright setting and two NV-compatible options. In addition, you can choose between 3 different models: a 1 MOA dot, a 2.5 MOA dot, or a 5 MOA dot…
The 2.5 MOA dot option is the most popular as it helps you shoot fast and accurately, and for me personally, it is my favorite option. The top-loading battery feature is also fantastic because it makes battery changes quick and easy (with no need to remove the optic from your gun), and one CR2032 will last you for around 3 years…
Similar to the RMR, you will need an adapter plate to mount this optic to your X5 Legion (here’s one that I like), and overall, the SRO is among the elite pistol red dot options…
So all in all, the Trijicon SRO is another great option for your Sig P320 X5 Legion because it’s durable, gives you a huge sight window, and has fantastic battery life with a quick-change battery compartment.
The Trijicon SRO Features And Benefits
| Large Field View | Parallax-free, clear sight picture, and compatible with suppressor-height iron sights. |
| Top-Loading Battery | Easy and quick battery changes without losing focus |
| Clear and Crisp Dot | The illuminated reticle and clear front lens allow a perfect field view |

4. Holosun 507C X2 (Great Budget Option)
Number 4 on the list is one of my favorite pistol red dot sights, the Holosun 507C X2, and there are many reasons why I like it. Firstly, the HS507C is an affordable open reflex pistol sight, and secondly, it’s a Holosun which means it’s packed with tons of useful features…
For example, the 507C is a very robust optic. It has a high quality aluminum sight housing that is built to withstand impacts, and it’s also rated to be IP67 waterproof which means it can easily handle rainy or snowy conditions…
On top of that, it features Holosun’s Multiple Reticle System which gives you 3 reticles to choose from in one sight. The 3 choices that you get are a 2 MOA dot, a 32 MOA Circle, or the combination of the two, the Holosun Circle Dot Reticle…
All 3 reticles are useful but my favorite is the Circle Dot Reticle because the large 32 MOA circle helps you acquire targets with lightning speed, but at the same time, you still have a small 2 MOA dot in the center when you need to make shots that require a high degree of accuracy…
On top of that, the 507C runs on 1 CR1632 battery which gives you a whopping 50,000 hours (5 years) of battery life. It also features Holosun’s Shake Awake technology (which will save you even more battery life), a Solar panel (which will allow you to run the optic without a battery), and a side loading battery tray to make battery changes fast and easy when the time comes…
Last, the 507C also features the Trijicon RMR mounting footprint which means you can easily mount it on to your P320 X5 with the use of an adapter plate (here’s an adapter plate that I like)…
So all in all, I love the Holosun 507C because it’s a more affordable option than some of the others on this list, but at the same time, it doesn’t sacrifice on quality, and that 3 reticle options can really help you customize the reticle to what works best for you.
The Holosun 507C X2 Features And Benefits
| Super LED | It provides a quality illuminated reticle catering to bright and low-light scenarios |
| Multilayer Lens Coatings | To allow optimal light transmission, durability, and less glare |
| Multi Reticle System | It combines the 2 MOA dot with a 32 MOA circle for better target acquisition |
| Shake Awake | To preserve battery life |
| Solar Failsafe | Provides power when your battery does not |

5. Crimson Trace RAD Pro (Great Budget Option)
Number 5 is the new kid on the block, the Crimson Trace RAD Pro, and apart from being a relatively new offering, it has some remarkable features and comes in at an affordable price…
It is a full-size open reflex Red Dot sight for full-frame pistols and it features a 3 MOA dot, which is a great size for fast target acquisition and shooting. It also gives you a large window, and it’s durable with the angles on the sight housing designed to protect the optic from impacts…
On top of that, its ambient light sensor will auto-adjust the dot’s brightness to the surrounding light conditions, and it will shut down after two minutes of no movement (thus saving you battery life) and then turn on again when the optic senses movement…
The battery life is ultra long and will last for around 20,000 hours (2 years) on one CR1632 battery, and you can change out your battery (when the time comes) from the top of the optic, so there’s no need to remove the sight from your slide and then go through the hassle of re-zeroing after…
Last, the CT RAD Pro features the Docter pattern footprint, and you can easily mount it to the X5 Legion with an adapter plate (such as the one here)…
So all in all, the Crimson Trace Rad Pro is another fantastic little red dot, that will pair nicely with the X5 Legion and won’t break the bank in the process.
