Making an SWEP play 2 animations for 2 different viewmodels

I have 2 viewmodels on my swep, one for the gun (v_model) and other is the hands (c_model)
The thing is:The v_model is not done like the tf2 ones (wich merges bones), instead, it has its own anims.

How do i make not only the gun, but the hands to make the animation at the same time?
Thanks
