How'd I fix CFrame.new(Position1, Position2)?

I'm kind of practicing my skills on a gun, and I want the gun to point at my mouse. Here's what I got for now:

local user = nil
local player = nil

script.Parent.Equipped:connect(function(mouse)
    user = script.Parent.Parent
    player = game.Players:GetPlayerFromCharacter(user)
    player.CameraMode = "LockFirstPerson"
    while wait() do
        script.Parent.Handle.CFrame = CFrame.new(script.Parent.Handle.Position, user.Humanoid.TargetPoint)
    end
end)

script.Parent.Unequipped:connect(function()
    if player ~= nil then
        player.CameraMode = "Classic"
    end
end)

Clean, no errors. But it follows my mouse, and my character's going forward. It's annoying, and would make me fall down from the BasePlate and die. Changing while wait() do end to something such as script.Parent.Handle.Changed:connect(function() end) or adding gyro, would be nice ideas, but I tried script.Parent.Handle.Changed:connect(function() end) and it didn't work, and adding gyro'd make it unable to jump.

Any ideas?

Thanks,
