SloMo Deagle issues

[MrMambl]

Hey,
I have a problem with a little addon that I wrote. It is a deagle that toggles a SloMo by rightclicking.
There are no errors but I want, that when the SloMo is on, the first clip of the deagle loses ammo, but when I use the deagle nothing happens when the SloMo is on, but when I toggle the SloMo of by Rightclicking the deagle loses ammo until the clip is empty.
Can anybody help me? (Sorry I'm new at coding)

This is the relevant code:

function SWEP:Timer()
finish = false
timer.Create("Timer",0.5,25, function()
	if self:Clip1() > 0 and finish then
		self:SetClip1( self:Clip1() - 1 )
	elseif self:Clip1() == 0 then
		finish = true	
	end
	if self:GetOwner():GetActiveWeapon() ~=	"weapon_ttt_slomodeagle" then
		finish = true
		end
	if finish == true then
	game.SetTimeScale(1)
	slow = 0
	return slow
	end
end)
end


function SWEP:SecondaryAttack()	
self:throw_attack()
self:Timer()
end


function SWEP:throw_attack()
if slow == 0 then	
	slow = 1
	game.SetTimeScale(0.2)	

elseif slow == 1 then
	game.SetTimeScale(1)
	slow = 0
end
return slow
end
