@Chuck Whitlock, @frozentundra,
Thanks for your extra level of patience with my "draw from a table top" question. I can tell it is one of those beginner questions that is so far off base it can be a bit exhausting to construct a polite answer. I wasn't finding videos or forum tips on how to 'table draw' because it's not a thing. I was basically asking the equivalent of how to get faster at texting while driving.
Thinking things through, I can see that this is covered under the umbrella of "Treat All Guns as Though They are Loaded", but as a beginner starting with online resources it's a little embarrassing that it's taken me this long (probably 40+ hours of reading, 20+ hours of videos) to start to understand the wider implications of what it means to "treat a firearm as if it is loaded". I'm sure in person instruction (next week, btw) will address this and more.
For my household I'm contemplating a 5th rule along the lines of
"a loaded pistol may only be in one of two places: a holster or in your ready grip"
Or perhaps
"always remove the mag and clear the chamber before setting down your pistol"
To be clear, there will be no live ammo loaded in my house until I'm through at least a couple of instruction sessions. And I don't plan to keep live ammo in the gun at any time except when it is holstered in my bedside safe or on my person.
