Gmod murder revolver viewmodel change

Should be real basic, I just need to replace the view model for the weapon_mu_magnum.lua to the viewmodel for the csgo r8 revolver.
In short laymans terms
i want people who log into my murder server to spawn with the r8 revolver (all the same coding as the magnum, 1 shot, 1 kill) instead of the magnum (if they are the sheriff of course) simple…

Change the SWEP.ViewModel

This is usually pretty good for viewmodels, works it out for you.

Problem is getting the world and view model for the r8 revolver…
