Adjusting the Held Position of a weapon.

Hey,

Now if you look into his hand you will just above that is a Grey Hand Granade. This as you know should be in the players hand not his wrist.

I need help making the grande go from his wrist into his hand however I dont know how to do that. Here is an image of the Grande in zModeler: (If that helps)



Really I'm stumped I just need help moving the grenade down. I just need someone to give short list of instructions. I'm happy to hand over the .dff upon request.
