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 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.

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

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).

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

Pros

  • Directly fits P365 optic cut slide
  • Good dot visibility under ambient lighting conditions
