I practice quite often to. Expert or better in all IDPA classifications. Class 'A' IPSC to, but I won't carry chamber empty even though I'd probably be better at it than most.
But I have met a few who have told me they carry chamber empty for piece of mind. They are afraid the gun might accidentaly go off. Now the ones carrying modern guns I tell them the gun is totally safe to carry chamber loaded but if any of them had older striker fired autos, yea I'd say either chamber empty or go by a newer gun!
Strangely none of them want to carry a revolver! I point out to them the wheelgun would be chamber loaded and just a pull of the trigger fires it but they prefer autos and using two hands to load it when danger comes.
