How to edit position of arms in a gun weld?

Here is the script. For the function welding.Holster, I want the arms to be positioned closer to the body, so that the gun barrel is a lot closer to the left leg. Currently it is way too far out.

This is what it currently looks like when in the sprinting position: 1 2 3

How would I edit the welding to do this?

wait(0.2)
local plr = game.Players.LocalPlayer
repeat wait() until plr.Character
local char = plr.Character
local tool = script.Parent

local crouching,sprinting = false,false
local welding = {}
local cframe, cframeXYZ, vector = CFrame.new, CFrame.fromEulerAnglesXYZ, Vector3.new
local create = assert(LoadLibrary("RbxUtility")).Create
welding.Weld = create("Weld"){}
local leftCrouchWeld, rightCrouchWeld = create("Weld"){}, create("Weld"){}
local arms = {
	Left = cframe(0.9,0.8,0.5) * cframeXYZ(math.rad(280),math.rad(40),math.rad(-2)),
	Right = cframe(-1,0.1,0.35) * cframeXYZ(math.rad(-90),math.rad(-15),math.rad(0)),
}

function welding.SetArms(bool)
	local torso = char:FindFirstChild("Torso")
	local leftS, rightS = torso:FindFirstChild("Left Shoulder"), torso:FindFirstChild("Right Shoulder")
	local left, right = char:FindFirstChild("Left Arm"), char:FindFirstChild("Right Arm")
	if bool then
		leftS.Part1, rightS.Part1 = nil, nil
		leftWeld = welding.Weld:Clone()
			leftWeld.Name = "Weld1"; leftWeld.Part0 = torso; leftWeld.Part1 = left; leftWeld.C1 = arms.Left; leftWeld.Parent = torso
		rightWeld = welding.Weld:Clone()
			rightWeld.Name = "Weld2"; rightWeld.Part0 = torso; rightWeld.Part1 = right; rightWeld.C1 = arms.Right; rightWeld.Parent = torso

		FakeLeftArm.Transparency = 0.6
		FakeLeftArm.Parent = tool
		local flaWeld = welding.Weld:Clone()
		flaWeld.Parent = FakeLeftArm; flaWeld.Part0 = left; flaWeld.Part1 = FakeLeftArm

	else
		sprinting = false
		char.Humanoid.WalkSpeed = 16
		leftS.Part1, rightS.Part1 = left, right
		if leftWeld and rightWeld then
			leftWeld:Destroy()
