Players keep fisting when gun is fired and also hold as fist

[SWGamer]

Hello I am new to gmod lua programming.I added a fist into the gamemode and it works good.
But then most times the players in third person view they shoot their weapons but they fire it by playing the fisting animation.And when idle with the gun the gun is holding up in hands by the fist idle animation

weapon_fists.lua is what I used.

Help will be appreciated.
