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 fits the P365 XL model directly by replacing the rear iron sight.

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

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

    Will Mount DIRECTLY To P365 XL Slide Without Any Mod

    Why Try This One - The Swampfox Sentinel mounts directly to the factory P365 XL optic cut slide without any modification. It's RMSc mounting footprint makes it a great hassle free option for anyone avoiding messing with aftermarket parts or DIY projects.

    7075 Body - Hard coated 7075 aluminum body for hard use and can handle up to 1500 G force on the slide during fast cycling

    Extra Protection - Optional to add IRONSLIDES SHIELD to beef up the lens hood to handle barricade racking, drop and other physical impact to protect optic internals

    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.

    sig p365 rmrcc

    Why pick the NEW RMRcc - This is the same 7075 T6 grade Trijicon RMR that many people love to use on their full size optic ready handguns, and the RMRcc is the smaller version for subcompact micro sized single stack CCW pistols.

    Upgraded Electronics - Better battery contacts to ensure it stays on after repeated recoil cycles. 

    No Compromise In Durability - The new RMRcc still uses the same grade material, circuitry, functionality the RMR is known for

    6.5 MOA Dot - Pick 6.5 MOA for pistol application. It's much bigger and rounder to see for someone with astigmatism under daylight (Learn more about 3 MOA VS 6 MOA here)

    Reduced 0.2" for slimmer profile - Fits flush on the P365 slide. It works better for custom milled slide so the optic can lock in very tight.

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


    Common FAQ

    Which MOA Size For A P365 Optic?

    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. Just make sure to dial the red dot brightness down at night

    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
