Filtering Enabled Gun is Broken?

Well, I am kinda new to FilteringEnabled, and currently I'm trying to convert my gun to work with FIlteringEnabled, I've had a friend help me, but until now I still can't get the gun to work, If any of you could show me what I did wrong :/

here is the Local script

Player = game.Players.LocalPlayer
Pistol1 = script.Parent
Ammo = 11
Mouse = Player:GetMouse()
shoot = false
reloading = false
MaxAmmo = 11
Mouse = Player:GetMouse()


function FireShooting()
    game.Workspace.ShootingServerEvent:FireServer(Mouse.hit.p)
            game.Players.LocalPlayer.PlayerGui.HUDs.PlayerHUD.Manabar.Ammobar.Size = UDim2.new((Ammo / MaxAmmo),0,1,0)
            local ammoy = Ammo
            game.Players.LocalPlayer.PlayerGui.HUDs.PlayerHUD.Manabar.Ammonum.Text = ammoy.."/"..MaxAmmo    
end

Pistol1.Activated:connect(FireShooting)

and here is the script for the gun

Player = script.Parent.Parent.Parent
Pistol1 = script.Parent
Ammo = 11
Mouse = Player:GetMouse()
shoot = false
reloading = false
MaxAmmo = 11
