How can I delay my CFrame?

This must seem like a weird question, but here it goes.

So in my game, my guns are created by CFraming the head of the player to the players mouse. I then CFrame the gun and arms to the head of the player. What im trying to do is delay the CFrame so i wont get the current Frame's CFrame it will be like the last frames CFrame. I dont want to loose the 60 frame speed i currently have with this weapon either. ( just so i dont have a stuttery weapon)

function load()
	
	Tool = script.Parent
	Player = game.Players.LocalPlayer
	Camera = game.Workspace.CurrentCamera
	Mouse = Player:GetMouse()

    local weld1 = Instance.new("Weld")
    weld1.Parent = Game.JointsService
    weld1.C1 = Player.Character.Head.CFrame:toObjectSpace(Player.Character.Torso.CFrame)
    weld1.Part0 = Player.Character.Torso
    weld1.Part1 = Player.Character.Head
	
	game:GetService("RunService").RenderStepped:connect(function() --What makes the head aim to the mouse
		weld1.C1 = CFrame.new(Player.Character.Head.CFrame.p, Mouse.Hit.p):toObjectSpace(Player.Character.Torso.CFrame)
	end)
	
end

wait(2)
load()

This is the script i use that makes the players head look torward their mouse.

Im looking to not run the current CFrame but make it delayed.

There is a way it's called the Delay function, Here is an Example layout(if you don't Understand the Wiki's layout).

Layout

function printer()--my Function
	print("Boom")
end

delay(5,printer)--this is where the delay gets used.

Now lets add it to your script:

Script Layout

function load()

    Tool = script.Parent
    Player = game.Players.LocalPlayer
    Camera = game.Workspace.CurrentCamera
    Mouse = Player:GetMouse()

    local weld1 = Instance.new("Weld")
    weld1.Parent = Game.JointsService
    weld1.C1 = Player.Character.Head.CFrame:toObjectSpace(Player.Character.Torso.CFrame)
    weld1.Part0 = Player.Character.Torso
    weld1.Part1 = Player.Character.Head

    game:GetService("RunService").RenderStepped:connect(function() --What makes the head aim to the mouse
        weld1.C1 = CFrame.new(Player.Character.Head.CFrame.p, Mouse.Hit.p):toObjectSpace(Player.Character.Torso.CFrame)
    end)

end

delay(2,load)

HOPE THIS HELPED!
