Jferreir, your assertion of how the gun should be used is very accurate in my book. However, what you describe with the trigger and the faint bulb light indicates a broken gun. Mine broke the same way last week after a year's light use and have ordered a new one. It has been well known to me that the zerostat's build quality isn't what it was - see also http://www.2spi.com/catalog/photo/zerostat.shtml
