So, a mod adds a new Gauss weapon, it's marked in it's plugin to have Energy Weapon as Equipment Type, no plugin loading after it changes that, yet in game it uses Guns icon and http://www.nexusmods.com/newvegas/mods/54643/? says it uses Guns skill too.

Is there something else that determines a weapon's related skill than the Equipment Type?

Edit: Never mind, i missed the obvious "Skill" field in the weapon data, several times, apparently
