How to link IK target with spawnable weapon?

You aren't able to - the IK target must always be a child of the current weapon. You can create a new child GameObject and then link to that.

okay thanks! And what if i want to change it per character for example? I will have to do some extra coding right?
 
Since the target GameObject is a child of the weapon the character will always place their hand at that position. It doesn't point to the character GameObject - it's on the weapon itself. This will make it independent of the character.
