How would I use First Person hands and a third person model.

Hi, I was wondering how I would be able to use my first person hand set for First person animations and my t$$anonymous$$rd person model for the players to view. Idk if it would be easier to just use the player model for first person ang t$$anonymous$$rd person. Cause only the player would be able to see the First person hands or Fp hands, And everyone else on say the server would be able to see the t$$anonymous$$rd person model. And how would I handle animations and switc$$anonymous$$ng weapons. I have all the scripts except for the t$$anonymous$$rd person model to play a walk and idle animation w$$anonymous$$ch would be easy. If you can help it would be much appreciated.
