Holosun 507K X2 - Best Overall

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

Why people love Holosun 507K - The 507K micro red dot sight is specifically designed for CCW single stack pistol with a flush slide fit and it's even more compact to carry. It's perfect for P365 XL model with that integrated rear iron sight for backup.

Motion Sensor Activated - ShakeAwake technology activates the reticle upon movement & deactivates when not in motion to save more battery juice.

Replaces The Rear Iron Sight - Integrated back up rear sight replaces P365's rear iron sights that the user took off to mount the optic. Great all in one feature for the P365

Snag Free Holster Draw - Works for IWB and OWB holsters. Nothing sticks out and nothing snags.

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


Trijicon RMRcc - Best For Duty Use

Recommended For Slide Cut Mount

Why pick the NEW RMRcc - Built from the same grade features as the original RMR, the RMRcc is thinner and more compact for Sub compact guns. However it does sit tall on the P365 with an adapter plate, therefore we recommend mounting this with a slide cut instead of the optic ready P365 XL.

6.5 or 3.25 MOA - 6.5 MOA is for fast target acquisition, and 3.25 MOA is for precise aiming and works for shooters with astigmatism

Upgraded electronics - Tighter battery grip prevents weak battery terminal contact due to drops, bumps or repeated recoils

No accidental brightness adjustment - The new “LOCK-OUT” Mode secures the setting regardless of bumping or rubbing against clothing when concealed.

Durable for single handed operation - Racking the slide against the optic on any hard surfaces. The 7075 T6 forged aluminum housing allows the user to go rough on the optic


Shield RMSc Best For Astigmatic Eyes

Will Mount DIRECTLY To P365 XL Slide Without Any Mod

Why use Shield RMSc – The RMSc shares the same mounting footprint as the original RMS red dot & Holosun 507K X2. It has the clearest lens and dot via a polymer lens for shooters with astigmatism. They gonna love it!

Perfect for single stack pistols - Fits flush on the a slide cut P365 or optic ready P365. Looks great, feels great and built tough.

Polymer glass optic for endurance - Withstand up to 10X greater shock impact than glass optics plus minimal lens reflection

Super lightweight for CCW - Carry it any where you go without feeling like there is weight on you.

The optic is powered by one CR2032 battery that lasts about 2 years (recommended to switch out every year).

4 or 8 MOA Dot Sizes - Recommend 6 - 8 MOA for the close distance the P365 is roughly designed to shoot.

Swampfox Sentinel - Best Value

Low Profile Lens Hood - Aim with both eyes open without thick lens frame getting in the way 

Manual Model -  Shake ‘N Wake motion sensing preserves battery life when Sentinel-M has been still for about 4 minutes and shuts off. When it senses motion, it resumes its previous brightness level. Highly recommend manual version for indoor low light use.

Common FAQ

What MOA Sizes Are Best For Sub-Compact Conceal Carry Pistols?

3 - 8 MOAs are great for sub-compact conceal carry handguns.

A larger dot is much easier to pick up, and it's much rounder for shooters with bad astigmatism to see, and it requires less brightness adjustment 

Highly recommend to checking out different ones physically in your local retail store first before making a buying decision.

Aftermarket Optic Plates - What Are / Aren't Compatible?

There are many aftermarket plates available for the P365, and sometimes it gets confusing on which ones are compatible when shopping online. 

For non optic ready P365 - Slide milling is the best way to go (The only way to mount Trijicon RMRcc currently)

For optic ready P365 - The factory slide is milled for the RMSc footprint, any optic with RMSc will fit right out of the box
