"There has to be a round in the chamber for a round to be fired" seems sort of tautological if I'm being honest.
Very, very few serious people would argue that anyone carrying a firearm should carry it without a round in the chamber. Yes, "Israeli carry" is a thing, but is almost entirely endorsed simply as a training carry-over from a time when people carried different weapons of widely varying mechanical safety features in a very unique high-threat environment.
If you're carrying a firearm professionally, or in the US "recreationally" for personal protection, carrying without a round in the chamber will be seen by most people as a pretty stupid decision.
As a Sig 320 owner, and someone that knows at least 3 other sig 320 owners, I disagree. None of us ever carry our weapon chambered. I probably know 10+ guys that own guns, including a few police officers, and I'm going to ask the officers about this because honestly, I would be surprised if they even carried their weapons chambered.
