[SOLVED] Why do I get multiple M1911s...?

The pictures explain most of it... First Picture (Lightshot), Second Picture (Also Lightshot), Third Picture (Yet Again, Lightshot)

So I really need help figuring out why I receive a random number of M1911's when I purchase the Developer Product.

+Rep to anyone who helps me, with logical/working answers.

If you don't feel like looking at the pictures (even though they explain everything better...),

Here is the LocalScript inside StarterPack:

local buyButton = game.Workspace.BuyButton.SurfaceGui.TextButton
local damageButton = game.Workspace.DamageButton.SurfaceGui.TextButton
local productId = 19635648

buyButton.MouseButton1Click:connect(function()
    game:GetService("MarketplaceService"):PromptProductPurchase(game.Players.LocalPlayer, productId)
end)

damageButton.MouseButton1Click:connect(function()
    game.Players.LocalPlayer.Character.Humanoid.Health = game.Players.LocalPlayer.Character.Humanoid.Health - 40
end)

Here is the Script inside Workspace.BuyButton:

local MarketplaceService = Game:GetService("MarketplaceService")
local ds = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")
local productId = 19635648

MarketplaceService.ProcessReceipt = function(receiptInfo) 

    for i, player in ipairs(game.Players:GetChildren()) do

        if player.userId == receiptInfo.PlayerId then

            if receiptInfo.ProductId == productId then
                game.Lighting:FindFirstChild("M1911"):Clone().Parent = player.Backpack
                game.Workspace.DisplayScreen.SurfaceGui.TextBox.Text = player.Name .. " has purchased an illegal M1911."
                wait(2)
                weapons = game.Lighting:FindFirstChild("M1911")
                local c = game.Players:FindFirstChild(player.Name).Backpack:GetChildren()

                for i = 1,#c do
                    if c[i].Name ~= "M1911" then

                    for i = 1, #weapons do
                        if weapons[i].className == "Tool" then
                        weapons[i]:clone().Parent = player.Backpack
                        end
                    end
                end
            end
        end 
    end
end
    local playerProductKey = "player_" .. receiptInfo.PlayerId .. "_purchase_" .. receiptInfo.PurchaseId
    ds:IncrementAsync(playerProductKey, 1)  

    return Enum.ProductPurchaseDecision.PurchaseGranted
end
