Until you're trained in Close Quarter Combat don't bother buying a collapsible baton. If you feel you need something get a baseball bat, wood or aluminum. Don't get real comfortable in the knowledge that you can hold any intruder that enters your house, though. If he has a gun your best defense is holding your hands in the air & pray. The second he sees a baton or bat he'll play his trump card & a gun trumps any CQC weapon.
I can see your distaste for shooting what could be an unarmed intruder, especially if your state doesn't have the Castle Doctrine. The best thing for you & your family's safety is a gun - any kind is better than nothing. I won't give you the standard mantra to shoot to wound. Wrong! Whichever you decide on train on & practice, practice, practice.
