There is a glitch in game that will make John’s Cattleman Revolver and Rare Shotgun use common Cattleman and Double Barrel ‘s icon. Finally I figured out how to fix this weapon icon bug. To do this you need to modify catalog_sp.ymt which is used by many mods. Here I provide a tutorial on how to do this.
Unfortunately I can’t upload my modified catalog_sp.ymt because it is based on JMRP (But this method would work on the catalog_sp.ymt from any other mod).
