How do I add spread to my raycast pistol?

I've recently made a pistol using raycast, I can't figure out how to add spread.

Local script

local BulletEvent = script.Parent:WaitForChild("BulletEvent")
local debounce = false
script.Parent.Equipped:Connect(function(Mouse)
 Mouse.Button1Down:Connect(function()
	if debounce == false then
		debounce = true
	script.Parent.BulletEvent:FireServer(script.Parent.BE.CFrame.Position,Mouse.Hit.Position)
	wait(0.5)
	debounce = false
	end
end)
	end)

Normal script

script.Parent.BulletEvent.OnServerEvent:Connect(function(Player, FromP, ToP)
 local RayCast = Ray.new(FromP,(ToP-FromP).unit*100)
 local Part,Position,Normal = game.Workspace:FindPartOnRay(RayCast,Player.Character, false,true)
 local Dist = (ToP-FromP).magnitude
 if not Dist then Dist = 300 end
 local Hole = game.ReplicatedStorage:FindFirstChild("GlockBulletHole"):Clone()
if Part ~= nil then
 Hole.Parent = Part.Parent
 Hole.Position = ToP
 Hole.CFrame = CFrame.new(Hole.Position, Hole.Position+Normal)
 local Weld = Instance.new("Weld")
 Weld.Part0 = Part
 Weld.Part1 = Hole
 Weld.C0 = Part.CFrame:Inverse()
 Weld.C1 = Hole.CFrame:Inverse()
 Weld.Parent = Hole
 if Part and Part.Parent:FindFirstChild("Humanoid") then
  Part.Parent.Humanoid:TakeDamage(30)
  Hole:FindFirstChild("Front").Texture =  "rbxassetid://2078208894"
  Hole:FindFirstChild("Back").Texture =  "rbxassetid://2078208894"
 end
	if Part.Parent ~= nil then
		if Part:FindFirstChild("IsGunHole") ~= nil then
	Hole:Destroy()
	else
 game.Debris:AddItem(Hole,10)
end
local gunshot = Instance.new("Sound", script.Parent)
gunshot.SoundId = "rbxassetid://356911785"
gunshot:Play()
script.Parent:FindFirstChild("Flare").MuzzleFlash.Enabled = true
wait(gunshot.TimeLength)
gunshot:Destroy()
end
end
end)
