Thanks everyone, I'll try finding that.
EDIT:
@Hera_: you're right, it wasn't making a fist, it was clasping. Haha, it was long ago since I used it so I kinda forgot how it looked.
@Kino: Thanks man, that was what I was looking for.
For anyone interested, the model path is "Abilities\\Spells\\Items\\AIso\\AIsoTarget.mdl"
