Featuring a unique Motion Sensor System and a scratch-resistant DiamondCoat Aspheric lens, the Leupold DeltaPoint Pro is the Best SIG P365 XL Red Dot.

Lets we’ll explore in this article.

Top 8 Best Red Dot for SIG P365 XL

1. Leupold DeltaPoint Pro – Best Choice

Testing the Leupold DeltaPoint Pro on my SIG P365 XL was a revelation in precision and usability. The sight’s Motion Sensor System, which stands out the most, is a practical tool that conserves battery life by powering down after 5 minutes of inactivity and instantly reactivating with any motion. 

Pair that with the DiamondCoat Aspheric lens, and you’ve got clear, bright target images that 

elevate your shooting experience. 

A simple 1 MOA click adjustment system makes adjusting windage and elevation easy. This sight isn’t just about features; it’s about enhancing every shot you make. 

I found it incredibly easy to replace the battery, too, without removing the sight from the gun. 

Flaw but not a dealbreaker

  • Finding a compatible mount to install the sight on the P365 XL can be challenging.

2. Trijicon RMR – Runner Up

Testing the Trijicon 6.5 MOA red dot sight on my SIG P365 XL has been a standout experience. The sight’s 6.5 MOA configuration made aiming at short range quick and remarkably accurate. 

I appreciate how the 8-level manual brightness adjustment and automatic setting allow me to tailor the optic to various lighting conditions. 

I can rely on its Military-grade Aluminum alloy housing; I didn’t have to worry about it handling the heavy recoil of the high-capacity P365. 

What sealed the deal for me was its lock mode, a brilliant feature preventing unintentional setting changes when holstered. 

Flaw but not a dealbreaker

  • A tad expensive, and may not be within everyone’s budget.

3. HOLOSUN HS507K – Highly Rated

When I mounted this red dot sight on my SIG P365 XL, it was the illumination system and battery life that truly stole the show. 

With up to 50,000 hours of power from a single lithium battery, this sight allowed me to enjoy extended sessions without any stress about battery failure. 

The Shake Awake Technology impressed me by shutting off the LED dot in low motion, extending the battery life even further. I found the automatic brightness control in varying light conditions particularly useful, keeping the sight crisp and clear. 

Flaw but not a dealbreaker

  • The battery side tray screw is too small, making it a bit tricky to handle.

4. Vortex Optics Viper – High Precision

Let me tell you about my time with the Vortex Viper Red Dot Sight on my SIG P365 XL. What really caught my eye was its quick target acquisition. 

With its 6 MOA dots, fast shots felt natural. Its low height allowed me to co-witness with iron sights, making my shots accurate and true. 

But what stood out was the durability – the hard anodized finish, O-ring seals, and Armortek coatings protected the sight from all sorts of mishaps. 

The manual brightness adjustment let me fine-tune the optic according to my needs. Simple and balanced, it worked like a charm!

Flaw but not a dealbreaker

  • You’ll need to unmount it for battery replacement, which isn’t ideal but certainly manageable.

5. Swampfox Sentinel – Great Value For Money

My hands-on experience with the Swampfox Sentinel on my SIG P365 XL was exceptional. This sight is built tough with polymer lenses and 7075-T6 aluminum, ensuring it can handle anything I throw at it. 

But the real star of the show is its brightness setting. The Sentinel-M (manual) with 10 brightness levels gives me total control, and the Shake ‘N Wake technology is just genius – it wakes up as soon as I move it! 

If you want something that combines durability with flexibility, this one’s a winner in my book.

Flaw but not a dealbreaker

  • Battery placement requires you to detach the optic to replace it – not a major issue, but worth noting.

6. SIG Romeo Zero – Smart Choice

Now let’s chat about the Romeo Zero Red I recently mounted on my SIG P365 XL. You want something that feels integrated with your gun? This sight does exactly that. 

The stippling pattern on the housing matches with the P365 XL grip pattern – it’s like they were made for each other. 

The Spectra coat HD polymer lens is a real game-changer, offering a brightness that works in 

any lighting condition. 

And the Motion Activated Illumination System? It’s like the sight reads my mind, turning on when 

I’m ready to fire. Honestly, it feels like a seamless extension of my P365 XL, offering precision and ease like no other.

Flaw but not a dealbreaker

  • Limited field of view, but it’s something you can get used to with time.

7. Shield Reflex Sights – User Friendly

Trying the Shield Reflex Mini Red Dot on my SIG P365 XL was exceptionally satisfying. With two MOA dot types, it’s as flexible as you’d want it to be. 

And the lens? Shield nailed it with their multilayer coatings, adding that extra anti-reflective touch. 

What really got me was the automatic brightness adjustment system, which always giving me the perfect view. It was like the sight knew exactly what I needed. The longer-lasting CR2032 battery was another advantage, never leaving me in the dark.

Flaw but not a dealbreaker

  • The sight lacks an auto turn-on/off system, so it’s always on. It’s something to be mindful of but doesn’t overshadow the sight’s brilliant features.

8. Viridian RFX – Honorable Mention

Let’s talk about Viridian’s RFX15 Green Dot Reflex Sight. If you think red is all the rage, wait till you try green. It’s a refreshing change and easy on the eyes. 

Testing this on my SIG P365 XL was pure joy. Weighing just .65 oz, it’s lightweight, but don’t let that fool you. 

Its Instant On technology had me hooked; just a simple movement and the 3 MOA green dot was there, ready to go. The two-minute shut-off? Smart, especially when it guarantees over 30,000 hours of battery life. 

With eight adjustable settings plus two for night vision, it’s a real game-changer. I mean, 6061-T6 Aluminum alloy housing and glass lens? Talk about quality. This sight is now a staple in my gear.

Flaw but not a dealbreaker

  • No auto-adjust feature on this one, but it’s easily outweighed by its other fantastic features.
