Holosun 507K X2 - Best Overall

sig p365 red dot

Mounts Directly To Optic Ready P365 XL Without Any Mod Or Special Mounting Plate

I really appreciate the Holosun 507K, and here's why it's a favorite of mine. As a micro red dot sight, it's hands down the best option for my Sig P365, specifically the P365XL model.

Motion Sensor Activated - I find the Motion Sensor Activation with Shake Awake technology to be a fantastic feature. It's great how it activates the reticle when I move it and then deactivates it when it's idle, all while helping to save battery life.

Fast and Accurate Shots - For me, what really stands out is its ability to deliver fast and accurate shots. It boasts Holosun's multiple reticle system, offering the choice of a center 2 MOA dot size or a 32 MOA ring. 

Snag Free Holster Draw - It works for IWB and OWB holsters. Nothing sticks out and nothing snags. You may have to test your own holster to see

Closed Emitter - Fully weatherproof against dirt, water and other debris from entering the optic

Swampfox Sentinel II - Best For Conceal Carry

Mounts DIRECTLY to optics ready P365 XL Without Any Mod

The Swampfox Sentinel 2 has been completely upgraded and improvement from its first generation model. The lens frame is thicker, larger window size (1X20mm compared to the original 1X16mm).

The body is more bad ass looking and the turret adjustment feels much more positive than before for accurate MOA adjustment.

Cyelee CAT Pro - Best Price

p365 cyelee cat pro

The Cyelee CAT Pro is one awesome RMSc red dot sight that is new to the market. It fits on the P365 perfectly, and the optic has durable construction and its a good value for the money you will spend.

The rear sight cutout acts as the back up rear sight on the P365, since the P365 

In terms of the body design, the Cyelee CAT PRO goes beyond aesthetics. It has increased its resilience with a thicker window frame, designed to endure drops and impacts. The optics deck has been slimmed down, and the rear iron sights reworked, now offering better compatibility with standard pistol front iron sights.

  • Reticle: 2 MOA + 25 MOA Ring
  • Turret Value: 1 MOA / Click
  • Window Size: 0.65" X 0.83"

Trijicon RMRcc - Best Durability

p365 red dot

I've had the chance to experience the Trijicon RMRcc red dot sight, and let me tell you, it's incredibly rugged, especially when matched with my single-stack Sig Sauer P365 pistol. It's hands down the best red dot optic for my custom-milled P365.

I've noticed a significant improvement in its electronics. The upgraded battery contacts ensure that it stays powered on even after enduring repeated recoil cycles.

What's really reassuring is that the new RMRcc maintains the same high-grade material quality construction, circuitry, and functionality that the RMR series is known for. So, there's absolutely no compromise when it comes to durability and performance. It's a top-notch choice all around.
