Well, I can't offer anything for insight... I live in Canada where we don't have the terms "compact" (translates here to Prohibited) and "home defense" which translates here to "unlawful storage."
For me to use a handgun for home defense, I'd have to go unlock the cabinet, unlock the trigger lock, unlock the ammo stored away from the handgun, load it, then I'd be ready.
As it stands, I'll just throw my clock radio at you instead.
Before anyone gets any ideas - long gun storage is less tight, so if need be, whatever's on my cleaning stand from the week's shooting may be at hand, instead... and all those are made to put bigger things than you in my freezer.
Not something I live in fear of... only been one "home invasion" around here I've heard of... and that was a teenager opening someone's door to ask for help for his friend that was beaten up in the lane.
