Mounting both CS:GO and CS:S and using both weapon game weapon models

[Acecool]

Hey, so I downloaded the new update and I'm about to launch it, but I noticed that CS:GO uses the same naming pattern for weapons as CS:S. I also noticed that CS:GO weapons do not show up when mounted but I can hear new footstep sounds and on the knife there is a new skin which is off. Does anyone know why we can't see the new CS:GO weapons and only hear the sounds ( single shot only, if you fire full auto only the first round sounds. )
