Help here needed! welding a Gun? [Solved]

function Weldnow()
local w1 = Instance.new("Weld")
w1.Parent = script.Parent.Handle
w1.Part0 = w1.Parent
w1.Part1 = script.Parent.Barrel
end

script.Parent.Equipped:connect(Weldnow)
script.Parent.Unequipped:connect(Weldnow)

this is my Script, it keeps pulling the Pieces together! so the Bullet shoots Down... plz help me here, how would I weld them without them being in the same Position?

Edit: tried this

function weldBetween(a, b)
    local weld = Instance.new("ManualWeld")
    weld.Part0 = script.Parent.Handle
    weld.Part1 = script.Parent.Barrel
    weld.C0 = CFrame.new()
    weld.C1 = b.CFrame:inverse() * a.CFrame
    weld.Parent = a
    return weld;
end
weldBetween(script.Parent.Handle, script.Parent.Barrel)

script.Parent.Equipped:connect(weldBetween)
script.Parent.Unequipped:connect(weldBetween)

and this

function weldBetween(a, b)
    local weld = Instance.new("ManualWeld")
    weld.Part0 = a
    weld.Part1 = b
    weld.C0 = CFrame.new()
    weld.C1 = b.CFrame:inverse() * a.CFrame
    weld.Parent = a
    return weld;
end
weldBetween(script.Parent.Handle, script.Parent.Barrel)

script.Parent.Equipped:connect(weldBetween)
script.Parent.Unequipped:connect(weldBetween)

but for these 2 it did fine, but except, it says either b is a nil Value or something else... sry I forgot about the other Error... this Stupid Output doesn't sho me the Old Errors for some Reason...
