There is an issue with the holdtype used for this weapon. Despite using a Deagle world model, it uses the Pistol holdtype instead of Revolver holdtype. This causes it to be held differently than the deagle normally is, giving itself away instantly. I'm assuming this is unintentional since otherwise there isn't much point in disguising it as a deagle.

Would it be possible to get a fix for this?

didn't work for us. it still removed all the perks
