Here are the 5 best red dot for Sig P365
These red dot sights fit on optic ready Sig Sauer P365 right out of the box, and they are great for concealed carry and range use. I have purchased, fitted, and shot these products on the P365 optic ready slide, and only keep the ones that work well on this guide.
One of my favorite Sig P365 red dot sights so far in 2023 is the Holosun EPS Carry.

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
Pros
- Directly fits P365 optic cut slide
- Good dot visibility under ambient lighting conditions
- Skeletonized lens frame to reduce weight
