[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

I don't have time to thoroughly look through this but I think I see where the issue is... I think line 15-26 is your issue

		weapons = game.Lighting:FindFirstChild("M1911")
                local c = game.Players:FindFirstChild(player.Name).Backpack:GetChildren()--okay so you look in the players backpack

                for i = 1,#c do --check all the items
                    if c[i].Name ~= "M1911" then--find items in the back that are m1911

                    for i = 1, #weapons do --so for every m1911 model you copy a tool
                        if weapons[i].className == "Tool" then
                        weapons[i]:clone().Parent = player.Backpack--this will eventually add up to a lot
                        end
                    end
                end

Look in that area for your issue. I'll look more into this in a few minutes. Playing League of Legends atm... lol

Can anyone help me...?
