Mike,
I know that hot ranges are a rarity as the example I posted happens at only one club. Every other match I've been to has cold range rules. At this club it typically goes like this, if I'm done shooting the COF, and did not go to slide lock, I simply insert a new magazine, and holster my weapon (under the RO's supervision of course). Now, I'm back to 10 +1. I don't touch my weapon again, until on the line at the next COF. For me, the "slide back, show clear, slide forward, hammer down" seem unnecessary, if you have your rudimentary gun-handling skills down, you should be able to holster a hot weapon. Heck, I bet a lot of you are hot right now, and no one is getting hurt.
Anytime we have low- no-light COFs, the overhead lights ARE turned on before, the shooter holsters his weapon. If its an outdoor shoot, there are multiple lights handy to illuminate the situation if needed. Ultimately, the shooter is always responsible for the state of his gun.
