Had an idea, wanted to know if this was legal or not.

Okay, If I had a +1 Spell Storing Greatsword, Can I cast a spell from a wand (More specifically, shocking grasp) from the wand into the weapon itself to be discharged later?

Honestly, I don't see why not. "Storing" is not particularly well defined, but I'm sure it expends a slot from a caster, so a charge from a wand is equivalent.

Spell Storing: "Once the spell has been cast from the weapon, a spellcaster can cast any other targeted spell of up to 3rd level into it."

Activating a wand is not casting a spell, it's using a magic item. See FAQ.

This is the same reason a magus can't Spellstrike with a touch spell from a wand.

*sigh* I was afraid of getting that answer. Very well. Thank you.

Just get a wizard to cast it for you
