i try to remove a tool from a table but the script still counts said tool as a part of the table?

So i have this script inside a tool that contains a numbervalue called "Ammo" the script will destroy the tool once it's value is equals or less than 0. The for i,v script will check if the Ammo's value is equal or less than 0 so that it will remove it from the table.

for i,v Script:

local backpack = plr.Backpack:GetChildren()
                for i,v in ipairs(backpack) do
                    if v:WaitForChild("Handle").Ammo.Value <= 0 then
                        table.remove(all9mm, v)
                    end

                    if v.Name == "9mm("..v.Handle.Ammo.Value..")" then
                        table.insert(all9mm, v) 
                    end
                end

                local chosenitem = all9mm[math.random(1, #all9mm)]

                local function reload()
                    ammo.Value = ammo.Value+1
                    chosenitem.Handle:FindFirstChild("Ammo").Value = chosenitem.Handle:FindFirstChild("Ammo").Value-1
                end

                repeat
                    reload()
                until ammo.Value == 15 or chosenitem:FindFirstChild("Handle").Ammo.Value == 0

Destroy tool Script:

local ammo = script.Parent:WaitForChild("Ammo")

ammo.Changed:Connect(function(value)
    if value <= 0 then
        wait(0.5)
        script.Parent.Parent:Destroy()
    end
end)
