As a compact and versatile concealed carry pistol, the Sig Sauer P365XL has become a favorite among shooters for its reliability, ergonomics, and accuracy.
One of the best upgrades for the P365XL is a red dot optic, which enhances speed and precision during target acquisition.
With a growing number of red dots on the market, finding the best red dot for your P365XL can be a challenge.
In this article, I’ll walk you through some of the top options available, backed by my personal experience and user feedback.
4 Best Red Dot Sights for Sig Sauer P365XL of 2024
1. Holosun 507K X2
Best Features:
The Holosun 507K X2 stands out for its multi-reticle system (MRS), allowing you to switch between a 2 MOA dot, a 32 MOA circle, or a combination of both. I particularly love this feature because the 32 MOA circle is great for quick target acquisition, while the 2 MOA dot excels at precision.
The optic is built with durable 7075 aluminum, offering excellent resilience to wear and tear. Additionally, the “shake awake” feature ensures the red dot is always ready when you need it, but conserves battery when not in use.
Advantages:
- Extremely long battery life
- Multiple reticle options
- Durable construction and compact size
- Affordable pricing compared to competitors
Disadvantages:
- Smaller window size compared to larger red dots (can feel limiting at first)
- Some users report slight difficulty in sighting in at first
Personal Experience:
I’ve found the Holosun 507K X2 to be an incredibly reliable companion on my Sig P365XL. Despite its smaller window size, it only took me a few sessions at the range to get used to it. Its durability stands out — I’ve carried this optic through various conditions, from rain to dusty environments, and it has held up flawlessly.
Positive User Comments:
- “The 507K X2 is everything I needed in a red dot for my P365XL. It’s reliable, durable, and I love the reticle flexibility.”
- “For the price, the performance is unbeatable. Battery life is excellent, and the shake awake feature is a game changer.”
Notes for Use:
Make sure the screws are securely mounted, and double-check the torque specs to avoid loosening over time. Also, practice with the circle-dot reticle to find which setting works best for you.

2. Trijicon RMRcc
Best Features:
Trijicon is renowned for its battle-proven durability, and the RMRcc is no different. Built from forged aluminum, it can withstand extreme abuse, making it a fantastic option if you prioritize ruggedness. The automatic brightness adjustment feature is also a strong point, as it ensures the red dot adapts to changing lighting conditions, which can be invaluable in defensive situations.
Advantages:
- Exceptionally durable and impact-resistant
- Available in multiple dot sizes (3.25 MOA or 6.5 MOA)
- Ideal for professional or duty use
Disadvantages:
- Requires adapter plates for installation on the P365XL
- Higher price point than some competitors
Personal Experience:
I’ve taken the RMRcc through some intense shooting drills, and it has never failed me. Whether I was shooting in broad daylight or low-light conditions, the automatic brightness adjustment ensured the dot was always visible. However, the mounting process requires an additional adapter, which might be a drawback for those looking for a simpler installation.
Positive User Comments:
- “This thing is built like a tank. I’ve dropped my pistol more times than I care to admit, and the RMRcc still holds zero.”
- “It’s expensive, but when your life depends on it, the cost is worth it.”
Notes for Use:
Ensure you purchase the correct adapter plate for mounting on your P365XL. Take the time to familiarize yourself with the automatic brightness adjustment, as it might feel different compared to manually controlled settings.

3. Sig Sauer Romeo Zero
Best Features:
The Romeo Zero is designed specifically for the P365XL, ensuring a perfect fit. It’s also the lightest red dot in its category, which helps maintain the gun’s balance. With 8 brightness settings and a scratch-resistant polymer lens, it’s a solid, affordable option. The clear polymer lens is another big feature for weight reduction, though it may not be as clear or durable as glass lenses.
Advantages:
- Lightweight and tailored for P365XL
- Budget-friendly
- Simple, user-friendly interface
Disadvantages:
- Polymer lens is more prone to scratching than glass
- Shorter battery life compared to competitors
Personal Experience:
For those looking for a budget-friendly option, the Romeo Zero does a good job. It’s incredibly lightweight, and I barely notice it on my P365XL. However, the polymer lens has shown minor wear after months of carrying, so if you’re rough on your gear, you might want to consider other options.
Positive User Comments:
- “Perfect fit for the P365XL. The red dot works great and holds zero very well.”
- “It’s a great option if you want something that’s reliable and not too expensive.”
Notes for Use:
Keep the lens clean and protected from potential scratches. It’s also important to change the battery before it gets too low, as the battery compartment is underneath the optic, requiring removal to replace.

4. Shield Sights RMSc
Best Features:
The Shield RMSc has a well-deserved reputation in the concealed carry world. Its auto-brightness feature is responsive to ambient light, and its compact design fits seamlessly onto the P365XL. One feature that stands out is its clear polymer lens, which is tough and resilient, though, as with the Romeo Zero, it can be prone to scratches over time.
Advantages:
- Ultra-compact and lightweight
- Automatically adjusts brightness
- Ideal for deep concealment
Disadvantages:
- Smaller window size
- Battery life is average compared to other red dots
Personal Experience:
I’ve used the RMSc on my P365XL for daily concealed carry, and its compact size makes it almost unnoticeable. The automatic brightness adjustment works well in most situations, though I’ve found it sometimes doesn’t get bright enough in extremely bright outdoor environments.
Positive User Comments:
- “Super lightweight, and I love how low-profile it is. Great for concealed carry.”
- “The auto-brightness makes it really easy to use. It just works.”
Notes for Use:
Be mindful of the polymer lens — clean it regularly to avoid scratches. The auto-brightness setting may take a little getting used to, especially if you’re transitioning from manual brightness control optics.
