How to weld a part to the Character's hand?

local base = game.Players:WaitForChild("Player1").Character["Right Arm"]
local han = workspace.handle
han.Anchored = true
local w = Instance.new("Weld", han)
w.Part0 = han
w.Part1 = base
w.C0 = CFrame.new()
w.C1 = base.CFrame:inverse(0,0,-20)
han.Anchored = false

This script works, but it doesn't weld the part straight on the character's hand, instead, it welds it some distance away from the hand. How can I weld it straight onto the Character's hand?

nevermind, I got it by taking away the C1
