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 the best Sig P365 red dot sight. It mounts directly on the P365XL model by replacing the rear sight with compatible mounting plates, screws included

Motion Sensor Activated - Shake Awake technology is a great feature that activates the reticle upon movement & deactivates it to save more battery life when in idle.

Fast and Accurate Shots - This is one of the best Sig Sauer P365 red dot optics with Holosun's multiple reticle system to provide fast target acquisition with just a center 2 MOA dot size or the 32 MOA ring.

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

Shield RMSc - Best For Astigmatism

Referenced Live Free Armory

Why use Shield RMSc red dot sight – The RMSc shares the same mounting footprint as the original RMS pistol red dot sight & Holosun 507K X2. It's one of the high quality pistol red dot sights featuring a polymer lens for shooters with astigmatism.

Polymer glass optic for endurance - The red dot can withstand up to 10X greater shock impact than glass optics plus minimal lens reflection

Super lightweight for a concealed carry gun - Carry it any where you go without feeling like there is weight on you. 

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

3 or 8 MOA Dot Sizes - Actually, 6 - 8 MOA red dot sizes are the best red dot sight clarity for pistol use


  • Directly fits P365 optic cut slide
  • Good dot visibility under ambient lighting conditions
  • Skeletonized lens frame to reduce weight
  • Polymer lens or glass models offered


  • Much expensive than others recommended 
  • Swampfox Sentinel - Best Value

    The Swampfox Sentinel red dot sight fits the factory optics ready Sig Sauer P365 XL without any modification using the RMSc mounting footprint

    7075 Body - Hard coated 7075 aluminum body for hard use and can handle up to 1500 G force 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

    Max Situational Awareness - Aim P365 with red dot and keep both eyes open to see everything around

    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. 

    Auto Model - A photosensitive sensor on the left side of the body provides good automatic brightness adjustment relative to ambient light conditions. There are no manual controls at all

  • Trijicon RMRcc - Best Durability

    p365 red dot

    The Trijicon RMRcc red dot sight is extremely rugged for the single stack Sig Sauer P365 pistol. It's the best red dot optic to go on a custom milled P365.

    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 quality construction, circuitry, and functionality the RMR is known for

    6.5 MOA Red Dot - Pick 6.5 MOA red dot for accurate shots. It's much bigger and rounder to see for someone with astigmatism under daylight (Learn more about 3 MOA VS 6 MOA

    Reduced 0.2" for slimmer profile - Fits flush square top on the base model the Sig P365 without sticking out on the side

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