Function is glitchy.

[I'm great]

My weapon is supposed to hit 2 times if pressed mouse once, but it either does 2 hits, or 1.
That's my code:

function SWEP:Think()
self:Stuff()
	if CLIENT then return end
	if ( self.Owner:KeyPressed( IN_ATTACK ) ) then
		if self.Owner.lastpressed == nil or self.Owner.lastpressed + .3 < CurTime() then
		self.Owner.lastpressed = CurTime()
		self:PrimaryAttack()
		self.doubleshoot = CurTime() +.3
	end
	end
	if self.doubleshoot and CurTime() > self.doubleshoot then
		self.doubleshoot = nil
		self:PrimaryAttack()
		self.stopattack = CurTime() +.6
	end
	
	if self.stopattack and CurTime() > self.stopattack then
		self.stopattack = nil
		self.doubleshoot = nil
	end
end

Why don't you just make it fire two bullets on primary attack instead of checking every tick? Unless the primary fire is something really complicated.
