Bullets won't show up after gun fires? (SOLVED)

So I have a gun that I am making and it was firing and showing the bullets coming out a few moments ago, but now I did something to make it stop showing the bullets.

So I have a local script inside the "Pistol" Tool. This script is as follows

-- Replicated Storage
local ShootEvent = game.ReplicatedStorage:WaitForChild("ShootEvent")

-- Player
local player = game.Players.LocalPlayer
local Mouse = player:GetMouse() 


-- Pistol Related Variables
local Ammo = script.Parent.Ammo
local MaxAmmo = script.Parent.MaxAmmo
local BulletVelocity = 25
local FireRate = .1
local BulletDamage = 15
local Pistol = script.Parent
local Reloading = false
local Barrel = script.Parent.Barrel
local Difference = 0 
local StopFiring = false

-- Pistol Special Features
local PistolGui = script.Parent.PistolGui

-- When Equipped
Pistol.Equipped:Connect(function()
    PistolGui.Parent = player.PlayerGui
    PistolGui.PistolFrame.AmmoAmount.Text = ""..Ammo.Value.."/"..MaxAmmo.Value
    Pistol.Barrel.Anchored = false
    Pistol.Handle.Anchored = false
    -- Player Clicks down to fire (Semi Automatic without While loop)
    Mouse.Button1Down:Connect(function()
        if StopFiring == false then 
            if Ammo.Value <= 0 then 
                StopFiring = true
                if MaxAmmo.Value > 0 and Reloading == false then
                    -- Reload
                elseif MaxAmmo.Value  <= 0 then
                    -- No Ammo
                end
            elseif Ammo.Value > 0  then
                local head = game.Workspace[player.Name].Head.CFrame.lookVector
                local mouse = CFrame.new(game.Workspace[player.Name].Head.Position,Mouse.Hit.p).lookVector

                ShootEvent:FireServer(Barrel, mouse,"Pistol", BulletVelocity, BulletDamage)
                Ammo.Value = Ammo.Value - 1
                PistolGui.PistolFrame.AmmoAmount.Text = ""..Ammo.Value.."/"..MaxAmmo.Value
                wait(FireRate)
            end
        end
    end)
end)

-- Unequipped Pistol
Pistol.Unequipped:Connect(function()
    PistolGui.Parent = Pistol
end)

I have the Server Side Code that is called when the gun shoots:

-- Replicated Storage  For Shooting
local ShootEvent = game.ReplicatedStorage:WaitForChild("ShootEvent")

ShootEvent.OnServerEvent:Connect(function(player, Barrel, Mouse, BulletName, BulletVelocity, BulletDamage)
        local Bullet = game.ServerStorage.Bullets:WaitForChild(BulletName):Clone()
        Bullet.Position = Barrel.Position
        Bullet.Parent = game.Workspace

        Bullet.Velocity = Mouse * BulletVelocity
end)

Thank you.

Updated Information: The OnServerEvent Listener isn't being ran. I put print statements in it with new line characters and it still would not print. It was working before so I didn't want to bring this up but I will just for the sake of reference: The server script is a module script (Not using the module part for this but I just put it in there for organization).

SOLUTION: So since the server replicated storage code was in a module script it wasn't working. I moved it to a normal script and it showed the part right away. Not sure why it was working before with it in there but whatever.
