Why is it So that my Filtering Enabled Gun Works in Studio, but not in the Real Game?

My filtering enabled gun works fine in studio, but the bullet just floats in game. I need some help

Would it be that my filtering enabled gun script shouldn't be in the workspace, or is there another problem?

Local Script for Gun Tool

Player = game.Players.LocalPlayer
local Gui
Ammo = 10
script.Parent.Equipped:connect(function(Mouse)
    Gui = script.Parent.AmoGui:clone()
    Gui.Parent = Player.PlayerGui
    Mouse.Button1Down:connect(function()
        if Ammo > 0 then
            workspace.FE.PistolShot.Shot:FireServer()
            Ammo = Ammo - 1
            Gui.BG.Text.Text = Ammo.."/10"
        end
    end)
    Mouse.KeyDown:connect(function(Key)
        if Key == "r" and Ammo < 10 then
            Gui.BG.Text.Text = "Reloading..."
            workspace.FE.PistolShot.Reload:FireServer()
            wait(1)
            Ammo = 10
            Gui.BG.Text.Text = Ammo.."/10"
        end
    end)
end)
script.Parent.Unequipped:connect(function()
    Gui:remove()
end)

Script for Shooting Gun

local Bullet
script.Shot.OnServerEvent:connect(function(Client)
    local R = script.GunShot:clone()
    R.Parent = Client.Character.Pistol.Handle
    R:Play()
    Bullet = Instance.new("Part", workspace)
    Bullet.Size = Vector3.new(1, 1, 1)
    Bullet.Transparency = 1
    local Trail = script.Beam:Clone()
    Trail.Parent = Bullet
    Trail.Enabled = true
    local A0 = Instance.new("Attachment", Client.Character.Pistol.Handle)
    local A1 = Instance.new("Attachment", Bullet)
    Trail.Attachment0 = A0
    Trail.Attachment1 = A1
    Bullet.CFrame = Client.Character.Pistol.Handle.CFrame
    local Shoot = Instance.new("BodyVelocity", Bullet)
    Bullet.Anchored = false
    Bullet.CanCollide = false
    Shoot.Velocity = CFrame.new(Bullet.CFrame.p, Client:GetMouse().Hit.p).lookVector * 900
    Shoot.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
    Bullet.Touched:connect(function(hit)
        if hit.Parent:FindFirstChild("Humanoid") ~= nil then
            if hit.Parent.Name ~= Client.Name then
                Bullet.Anchored = true
                if hit.Name ~= "Head" then
                    hit.Parent.Humanoid:TakeDamage(10)
                elseif hit.Name == "Head" then
                    hit.Parent.Humanoid:TakeDamage(50)
                end
                Bullet:remove()
                hit.Parent.Killer.Value = Client.Name
            end
        end
    end)
    game:GetService("Debris"):AddItem(Bullet, 1)
end)
script.Reload.OnServerEvent:connect(function(Client)
    local R = script.ReloadSound:clone()
    R.Parent = Client.Character.Pistol.Handle
    R:Play()
end)
