At Gunsite, "make ready", means load pistol by putting a round in the chamber. This is obviously the definition shooters associate with a loaded pistol.
In my State (Nevada), the legal definition of a loaded firearm is a round in the chamber. This is both legal and practical.
In California, and some other States, a loaded firearm is one with loaded rounds in the magazine, and possibly, any round attached to the firearm in any way. This is a legal definition, and hardly practical.
Springer was correct: Jim W wasn't asking for Safety lessons that did nothing to contribute to answering his question. A little CONTRIBUTION along with the SAFETY LESSON would have been ok.
Regarding safety rules, "TREATING a gun as if it were loaded" suggests acting like it's loaded when we "know" it isn't. A Gun Is ALWAYS Loaded implies a heavier sense of responsibility with the knowledge that some day, it really will be when we're positive it isn't and that we'll be safe regardless---and that we assume full responsibility.
Additionally, I know that I'm being observed by all knowledgeable firearms owners, just as I observe them with regards to safety. I know what I think of those who are unsafe and I'll make sure they know it too. Of course, setting a good example for those just learning is paramount, also. Hope I wasn't too long winded.
