(1 review) Write a Review


This product is guaranteed to be 100% functional, and is still backed by our warranty ensuring proper function. Finish is not warrantied or guaranteed with products sold as blems.

These blemished products will show minor cosmetic imperfections. These imperfections may range from color variations in the anodizing finish, anodizing that is missing in small areas, and/or small surface scuffs. Please see the product pictures for examples of some of the blemishes you may see.

Most of the blemishes will be hidden from view when the adapter plate is mated to your slide, and an optic is installed.

This is a final sale item. Returns will not be accepted.



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

Each plate will ship with one set of M3x.5x8mm screws to secure the plate to the slide. 

Plates ordered to mount the Trijicon RMR/SRO will ship with the correct mounting hardware to mount Trijicon optics.

Plates ordered to mount Holosun "C" series optics (407c/507c/508t) will use the longer factory 6-32 screws provided by Holosun in the box with the optic. We do not provide the screws for mounting Holosun optics with this plate.

 It is solely the responsibly of the customer to ensure the correct fasteners are used and proper safe function of the firearm is maintained. If you have any questions, contact a competent gunsmith for help!


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