Holosun 507K X2 - Best Overall

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

Side Battery Tray - Access battery from the side with side loading battery tray, instead of the bottom. No sight removal or re-zeroing required after battery swap

Features:

• Magnification: 1X
• Reticle: 2 MOA dot, 32 MOA ring, or combined
• Turret Value: 1 MOA / Click
• Window Size: 0.58" X 0.77"
• Construction: 7075 T6 aluminum IP67 rated
• Dimension: 1.6" X 0.98" X 0.95"
• Weight: 1 oz
• Battery Life: 50,000 hours

Holosun EPS Carry - Best Weatherproof

The Holosun EPS Carry is full weatherproof and it directly mounts on the optics ready Sig Sauer P365 with an RMSc mount adapter plate with recoil lugs provided.

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

Tight Optic Fit - The EPS Carry locks in tight on around the index posts, and the recoil lugs prevents the optic from shifting  

Side Battery Access - It's the same as Holosun 507K, so easy to swap the battery without sight removal

6 Reticle Systems - 2 MOA dot, 6 MOA dot and mutli reticle system with 32 MOA ring (with solar failsafe). Sold separately

K Pattern Mounting Footprint - It uses the RMSc footprint only if using the provided adapter plate

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.

One thing that stands out the most for the P365 XL user is the ability to add the missing rear iron sight on the optic's forward overhang to co-witness the front sight. 

Features:

• Magnification: 1X
• Reticle: 3 MOA
• Turret Value: 1 MOA / Click
• Field of View: 1X20mm

Cyelee CAT Pro - Best Price

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.

Features:

• Magnification: 1X
• Reticle: 2 MOA + 25 MOA Ring
• Turret Value: 1 MOA / Click
• Window Size: 0.65" X 0.83"
• Construction: 7075 T6 
• Weight: 1 oz
• Battery Life: 50,000 hours

Trijicon RMRcc - Best Durability

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.

Features:

• Magnification: 1X
• Window Size: 0.5" X 0.74"
• Reticle: 3.25 or 6.5 MOA
• Turret Value: 3 MOA / click
• Construction: 7075 T6 forged aluminum
• Dimension: 1.8" X 0.95" X 0.97"
• Weight: 1 oz
• Battery: 1 CR2032 battery
