Having an issue with press R to reload script, how can I fix it?

Trying to make an FPS game, made a press R to reload script, however, once I reload, every time I shoot, it automatically reloads, even if I've only shot one bullet. Any suggestions on how I can fix it?

userInput.InputBegan:Connect(function(input, gameProcessed)

if not gameProcessed then
    if input.UserInputType == Enum.UserInputType.Keyboard or Enum.UserInputType.Gamepad1 then
        local keycode = input.KeyCode
        if keycode == Enum.KeyCode.R or Enum.KeyCode.ButtonX then
            reload_sound:Play()
            reload_sound.Ended:Wait()
            gun.Ammo.Value = 12
        end

    end
end

end)
