Line Trace Start point on pawn

Hi, my problem is that I want to let a line trace start from my pawn’s weapon to somewhere but when my pawn is turning the start point is not turning right with me and does some strange translation. What is the solution for dthis problem. I also work with replicating this trace line.

Could you explain a little bit more what your problem is? Do you have a socket where your weapon is and where you want to fire from?
