Problem with SWEP Silenced attack

[JFA]

I'm working on my custom SWEP base and already added silencer support
Here is my part of Primary attack code that responsible for viewmodel's attack animations
 if self:GetNWBool("Silenced") == true then 
  if  self:Clip1() > 1 then
   self:SendWeaponAnim( ACT_VM_PRIMARYATTACK_SILENCED )
  elseif self:Clip1() == 1 then
   self:SendWeaponAnim( ACT_VM_DRYFIRE_SILENCED )
  end
  self:EmitSound(Sound(self.Primary.SilencedSound)) 
 else
  if  self:Clip1() > 1 then
   self:SendWeaponAnim( ACT_VM_PRIMARYATTACK )
  elseif self:Clip1() == 1 then
   self:SendWeaponAnim( ACT_VM_DRYFIRE )
  end
  self:EmitSound(Sound(self.Primary.Sound)) 
 end
But ACT_VM_PRIMARYATTACK_SILENCED doesn't work. It shoots but without silencer (It hides and I don't know why). Other custom SWEPs works pretty good with such code, but not my.
Can anyone help with that ?

Does the model support those activities? Are you sure the NWBool is set to true server-side?
