I want to not be able to see hands in multiplayer fps game


I am currently in the process of making an FPS game and I need some help. How can I make a weapon look like it’s floating in front of the character but really when you are viewing the player in multiplayer you can see that they are holding the weapon? I am not sure if this is possible but the reason I want to do this is because it matches the theme of my game. Please ask if you need a further explanation.

Many Thanks
