The person who has fired a 22 target pistol extensively might be better off using it than they would trying to operate an unfamiliar rifle or shotgun under stress. I said unfamiliar because the term applies to weapons like an AR or 590 or 870 bought and then placed behind a door. I'm not implying that a .22 anything is sufficient or that using a handgun beats using a long gun. The fact that shotguns are passé as in no longer trendy does not negate their usefulness in home defense.
