Trying to fix these, scripts I made. They won't work and I'm literally annoyed.

Server Script Service

local debris = game:GetService("Debris")

game.ReplicatedStorage.weaponFired.OnServerEvent:Connect(function(A1,A2,A3,A4)
	if A3 == "DB" then
		print(A1,A2,A3)
		local bulletHole = Instance.new("Part",workspace)
			bulletHole.Size = Vector3.new(.2,.2,.2)
			bulletHole.Position = Vector3.new(A4.X,A4.Y,A4.Z)
			bulletHole.Anchored = true
			bulletHole.BrickColor = BrickColor.new("Black")
			debris:AddItem(bulletHole,10)
			bulletHole.CanCollide = false
		if A2.Parent:FindFirstChild("Humanoid") then
			A2.Parent.Humanoid:TakeDamage(50)
			elseif A2.Parent:IsA("Accessory") then
				A2.Parent.Parent.Humanoid:TakeDamage(50)
						local bulletHole = Instance.new("Part",workspace)
			bulletHole.Size = Vector3.new(.2,.2,.2)
			bulletHole.Position = Vector3.new(A4.X,A4.Y,A4.Z)
			bulletHole.Anchored = true
			bulletHole.BrickColor = BrickColor.new("Black")
			debris:AddItem(bulletHole,10)
			bulletHole.CanCollide = false
			
			elseif A3 == "Pistol" then
				print("pew")
				end
				end
			end)

game.ReplicatedStorage.playAudio.OnServerEvent:Connect(function(A1,A2,A3,A4)
	if A2 == "Reload" and A4 == "DB" then
		A3.Reload3:Play()
		wait(.3)
		A3.Reload3:Play()
		if A2 == "Shoot" and A4 == "DB" then
			A3.Handle.Fire:Play()
			A3.F1.Transparency = 0.5
		    A3.F2.Transparency = 0.5
		wait(.3)
		A3.F1.Transparency = 1
		    A3.F2.Transparency = 1
			if A2 == "Reload" and A4 == "Pistol" then
				print("Reloading")
				A3.Reload3:Play()
				print("R")
					if A2 == "Shoot" and A4 == "Pistol" then
			A3.Handle.Fire:Play()
			print("Pew")
			print("hi")
				end
				end
				end
				end
				end)

DB Shotgun script

local debounce = false
local Tool = script.Parent
local Handle = Tool:WaitForChild("Handle") or Tool.Handle
local ammo = 2
local uis = game:GetService("UserInputService")
local mouse = game.Players.LocalPlayer:GetMouse()
local spare = 20


function reload()
	if ammo == 0 and spare >1 then
		game.ReplicatedStorage.playAudio:FireServer("Reload",script.Parent,"DB")
		ammo = 2
		spare = spare -2
	end
end

Tool.Activated:Connect(function()
	local target = mouse.Target
	if not debounce and ammo == 2 and target ~= nil then
		debounce = true
		game.ReplicatedStorage.playAudio:FireServer("Shoot",script.Parent,"DB")
		game.ReplicatedStorage.playAudio:FireServer("Shoot",script.Parent,"DB")
		ammo = ammo -2
		game.ReplicatedStorage.weaponFired:FireServer(target,"DB",mouse.Hit)
		print("Sent to Server")
		debounce = false
	elseif  debounce == false and ammo == 0 then
		debounce = true
			Handle.Empty:Play()
			wait(0.3)
			Handle.Empty:Play()
			debounce = false
	end
end)


	uis.InputBegan:Connect(function(input)
		if input.KeyCode == Enum.KeyCode.R then
			if ammo == 0 then
				reload()
			end
		end
		end)
