If they have a handgun chances are I'm dead before I can draw my own and train one on them anyway. I'm not Clint Eastwood and this isn't a hollywood western. Whoever has the drop wins and by definition that's the intruder since I'm not going to spend every second of my life with a gun in my hand.
Projecting your claimed inadequacies, which I don't believe for a minute especially before you moved the goalposts from home defense ("I have [a baseball bat] in my closet") to a Spaghetti Western, says nothing about actual gun owners.
