    Trijicon RMRcc - Best Durability

    Requires custom slide or slide cut for RMRcc

    sig p365 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.

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

    Pros

    • Extremely durable mount on Sig P365
    • Offers smaller dot models
    • Very long battery life
    • Scratch resistant
    • Dot brightness lock mode

    Cons

    • Slide milling required or buy aftermarket slides

    Common FAQ

    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.

    Aftermarket Sig P365 Red Dot Adapter Mount Plates 

    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
