Default functions erroring with SWEP inheritance

[c👌de_g🎷]

I have my SWEP inheritance set up like this:

basecombatweapon -> weapon_dodbase -> weapon_dodbasegun -> weapon_dodfullauto_punch -> weapon_thompson

In basecombatweapon, I have this as the Holster function:

function SWEP:Holster( pSwitchingTo )

	// cancel any reload in progress.
	self.m_bInReload = false
	
	// Send holster animation
	self:SendWeaponAnim( ACT_VM_HOLSTER )

	return true
end

This works fine when holstering that specific weapon -- [URL="https://facepunch.com/showthread.php?t=1483883"]although I have my own problems with the actual anim[/URL]. When I holster any weapon inheriting from it however, it gives a shared error that SendWeaponAnim is a nil value. Here's a child weapon calling the basecombatweapon function:

function SWEP:Holster( pSwitchingTo )
	if ( not CLIENT ) then
		local pPlayer = self.Owner
		
		if ( IsValid( pPlayer ) ) then
			pPlayer:SetFOV( 0, 0 ) // reset the default FOV -- Fix second argument/should it immidiately reset?
			
			if ( self.m_iAltFireHint ) then
				pPlayer:StopHintTimer( self.m_iAltFireHint )
			end
		end
	end
	
	self.m_bInReload = false
	
	--self:SetSmackTime( -1 )
	
	return BaseClass:Holster( pSwitchingTo )
end

The code seems to work fine when I store the old holster in a variable then run it like that, however, it's a really hacky solution:

local holster = BaseClass.Holster

The same thing occurs with Clip1 in the Reload method in weapon_dodbasegun:

function SWEP:Reload()
	if ( self.m_bInReload ) then return false end
	
	local pPlayer = self.Owner
	local iClip1 = self:Clip1()
	
	local iResult = self:_DefaultReload( self:GetMaxClip1(), self:GetMaxClip2(), self:GetReloadActivity() )
	if ( not iResult ) then
		return false
	end
	
	return true
end

weapon_dodfullauto_punch and weapon_thompson will both error when reloading regardless of how much is in the clip, erroring again saying that Clip1 is a nil value.

Both errors are shared.

After doing some more research, it seems that SWEP.Weapon doesn't exist in the weapons for some reason. Also, not overriding the Holster function prevents the error.

Should be BaseClass.Holster( self, pSwitchingTo ).
