Question about first person.

So I am basically an absolute beginner at coding, animating and everything in between. I have a very stupid question. I am using blender for my 3d modeling and animating. When I am making a player, would the hands and guns that show up be it’s own model and animated desperately with it’s own gun or would the player model have the hands and I would animate the player model with the gun in their hands.

As I said I am a beginner so I am learning as I go. Thanks!

If you want to swap the gun later on, its easier to just parent it to the hand bone as a seperate model
