How to make fps hands lag a little behind camera rotation speed?

Im looking for a way to make my players hands lag a little behind the main cameras rotation, so if you look left or right really fast it takes a little bit of time for the hands to catch up. so it almost feels like your hands and head are separate.

I suggest making your hands and head (camera) separate game objects, pretty much like you said.

Then look around for ‘smooth follow’ scripts, and do some research on Lerp and Slerp.

Good luck.
