Except when they do. Even things like a tube-magazine bolt-action 22, because it can hold more than 5 rounds. NYC at it’s stupidest. The 113 year old 1911 .45 ACP has a standard seven round magazine, so you need to get rid of your old magazines and buy… er, I don’t know of any makers of 5-round 1911 magazines. Maybe they exist, but I’ve never seen one.
