Have you considered hand to hand skills? I would suggest these as well. Nothing fancy, no need for too many "techniques" just simple blocks and deflections.
Any time you bring a weapon into play you increase the chances of getting hurt by one. In most houses the close range makes it easier to hit your target. Tactics will teach you where to start and how to place your actions in order. Few will teach you how to fight over a gun if they grab it. I always start myself at the worst case scenarios, then work back.
