We’ve seen a Terminator taken down with an electric shock in film and in TSCC. Even though this only disables the Terminator for 120 seconds, but it seems a lot more effective than shooting at them with pistols or shotguns.
So… why not simply get a taser for protection instead. If you are lucky you can extract the chip. If you are not that lucky, at least you get an 2 minute head start to haul sorry-barb.
