I agree and understand Talon it IS quite OK to go with clearing your house with a spear or full length shotgun, but the (minor) point is it is easier with a short compact weapon, that has been proven beyond debate by history, From Stalingrad in ww2 to Vietnam the chosen weapon for clearing buildings and tunnels was grenades, entrenching tools, pistols, fighting knives etc. Come forward to today both the wests Police and Military train constantly to clear buildings using flashbangs, pistols, SMGs and very short shotguns.
Trying to point a 40 inch long shotgun round a corner into a room is definitely doable, but its quicker, easier with something more compact. Anyway its what works best for you that matters.
Pity we cannot have one of these each, just the sort of think for housing clearing in the UK with or wiping out your classmates in the US with !!
