[photon][RPC] GUI function to specific instanceID?

 if(collision.gameObject.tag == "weapon")
         {
             
             
         Debug.Log ("a Player's sword: ("+collision.gameObject.GetInstanceID()+"hit my body " +gameObject.GetInstanceID());
         
         this.myPhotonView.RPC("success", PhotonTargets.AllBuffered);
         }

is on the player mesh

 if(collision.gameObject.tag == "Player")    {
             Debug.Log (collider.GetInstanceID());
             if(myPhotonView.collider.GetInstanceID()==collider.GetInstanceID())
             {
             Debug.Log ("mySword"+ gameObject.GetInstanceID()+" - hitEnemy" + collision.gameObject.GetInstanceID());
                 
                 
             }
 
         }

This is on the weapon's script. Both these match: How do I send the sword that he hit specifically that enemy. I'm calculating % of hits done to player to display who killed who.
