GMod weapons are held like camera/pistol

My friend has been having this problem, when he enters my server. It looks like hes holding a camera or sometimes it like a one handed pistol thing. It’s only to him and it’s getting annoying, can someone help?

Make sure the weapons he is using run SetHoldType in the Initialize method.

How do I do that exactly? I’m not really informed as others.

Weapons that are having this problem should have this code present:

function SWEP:Initialize()

SetWeaponHoldType will not work.
