I used to have shotguns propped in corners loaded and safeties on. Then I learned that most shotguns don’t have the “drop safety” mechanisms most handguns have.
They now sit with the barrel empty, full magazine, the slide (pumps) partway open, safety off, and a sleeve with 5 extra shells on the butt.
It is ready about 5 seconds after I grab it (and with a full mag taking a shell from the sleeve) as I walk out to see what just went bump in the night.

The AR and AK aren’t ‘drop safe’ either by the same standards, but when was the last time you heard of one drop-discharging?
My Saiga 12 is ready within half a second of me grabbing it.
