Optic Adapter Plate - Sig P365X/XL/XMacro to Trijicon RMRcc

(5 reviews) Write a Review


This plate is compatible with the Sig P365X, Sig P365XL and Sig P365 XMacro slides only.

This plate is not compatible with the CA-Compliant Sig P365 (Model: 365-BXR3P-CA) due to the LCI on that slide. If you need a plate for a CA-Compliant P365 slide with LCI, it can be found here.


Each plate ships with one pair of M3x.5x8mm screws to secure the plate to the slide, and one pair of 5-40x.375 screws to secure the Trijicon RMRcc to the adapter plate.

Our adapter plate is CNC machined from billet 7075 aluminum alloy (almost twice as strong as the more common and cheaper 6061 Aluminum) and Type 3 hardcoat anodized black. To minimize unnecessary weight, the plate has had as much material machined away as possible without sacrificing any structural integrity.

Installation Instructions:

1. Ensure firearm is completely unloaded.

2. Secure plate to slide using M3x.5 screws - 10IP Driver - 12in/lb (clear bag).

3. Secure RMRcc optic to plate using 5-40x.375 screws - 10IP Driver - 12in/lb (red bag)

4. A small amount of Blue Loctite may be used. NOTE: DO NOT USE RED LOCTITE!

5. Use driver size and torque spec listed on bag.


Tools Required:

-10IP Driver

-Blue Loctite

    Optic adapter plate/sig 365 x macro tach ops to trjicon rmrcc

    This plate worked perfect. Mounted easily with no adjustments or forcing into place. Was able to torque the screws perfectly. I had purchased a mounting plate from another company and wasn’t comfortable with it but was assured by that company it would be fine. On the 10th shot at the range the optic came off the plate due to the screws not being long enough. If you want a plate that works as it should order from Maple Leaf Firearms. Also Chase was a big help after explaining the issue with the plate from another company.

    Customer service was amazing, never had a company offer to personally call to ensure the order was placed correctly. Once the plate arrived it fit perfectly, highly recommend Maple Leaf Firearms to anyone.
