You'll learn eventually, we all did. The most efficient way to do props like swords and guns is to make a shapekey in blender that shrinks the prop to 0 scale, then toggle that in your animations or emotes. For regular non-deformed meshes like swords and guns it's usually fine to have a separate mesh renderer that's only on some of the time. But for deformable clothes it's really expensive to have a whole separate skinned mesh.
