I have a JMCK IWB #3 for a P365 I purchased a while back. I ordered it with a red dot cut, but I’ve been using it with a non red dot equipped pistol.
I recently picked up a P365 XL Optics Ready pistol and mounted a Holosun 407K. Immediately I noticed the edge of the 407K has an interference with the edge of the holster.
I assume the older design of the P365 XL, where the optics cut replaced the rear sight, the optic would sit farther back and this interference would be a non issue.
My intuitively plan is to use sone fine grit wet/dry sandpaper and slowly remove material until the optic has clearance to the edge of the holster?
