pistol crossbow

[NorthernRaider]

Y'know pistol bows have a fairly cleary defined role in short range personal security but as with most things they require at modicum of skill to be used to their maximum advantage, so consider alternatives as well for example those large aerosols of wasps nest destroyer make a pretty formidable ersatz mace type spray. just point and squirt and a good blast of noxious chemical and propellant can be blasted at an intruder up to 10 feet away.
Dont confuse Wasp and Fly killing sprays with the much larger and more powerful NEST destroyer.

Another alternative is the 1 litre disposable dry powder fire extinguisher, that is really debilatating if your opponant gets blasted with that from up to 15 feet away.
