Storing Data and Access Efficiency

I have an array of weapon objects. I am trying to access them individually to pull out a texture variable. Should I create a base weapon class and modify the variables directly in the inspector, or create a mace/sword/spear class that extends the base weapon class? I would extend it, but accessing the textures for each specific weapon would be hard opposed to using a GetComponent(scriptWeapon) once, to saying GetComponent(scriptWeaponMace), GetComponent(scriptWeaponSword). Which one should I do?
