Thanks for suggesting GerMarkerReachedSignal, however it still stack firing.

animations.shootWithPump:GetMarkerReachedSignal("Pump"):Connect(function()
	PlayGunSound(TempTool.Sounds.Pump, TempToolBodyAttach, 20)
	flingshell(TempTool)
end)

animations is a table with humanoid:LoadAnimation, and this GetMarkerReachedSignal is inside a function, which is called when player inputs.
