I still like the idea of a neon transformer hooked up to the alarm/body.....10,000 volts if you touch it wearing anything but linemans gloves and boots. I would do it if it were not for all the dang lawyers, judges and silly laws. Not enough current to kill ya, but enough voltage to make that hand or finger seriously tender.'
Just as an aside for your shops/homes....you do not need to pay an alarm company $$$ to rig you up unless you want monitoring. You can get night/day infrared cameras (good quality) that hook up to your pc for recording + alarm systems that are very easy to install on the cheap. Just look at flea bay....most of it is standard security stuff except for the 500% markup. Now there is no substitute for a professionally installed system...but if your handy you can rig everything for under 1.5K unless you have a ton of windows/property. Battery backups on the pc and cameras, battery backup on the horn.
BTW I agree, a good ole 1911 is a great hole puncher. I am fond of a .40 Ruger myself.
