Trijicon RMRcc - Best Durability
Requires custom slide or slide cut for RMRcc
Why pick the NEW RMRcc - This is a smaller version of the Trijicon RMR red dot sight specifically designed for something like this single stack Sig Sauer P365 pistol.
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 accurate shots. 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 Sig P365 slide. It works better for custom milled slide so the optic can lock in very tight.

Which MOA Size For A Sig P365 Red Dots
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.
