As I've mentioned here several times, after force-on-force training for "wake up to someone standing in your bedroom" scenario, I don't consider a long gun as a nightstand/bedroom gun. The longgun needs room to work, and is a distance weapon, so there ARE areas of my house and property in which a a longgun absolutely makes sense, but in the moment my hand touches my longgun beside my bed, I already have had a loaded and ready pistol in my hand.
Philosophically, if a firearm is meant to be used, it needs a round in the chamber to be used. If the weapon is "secondary," not needed for immediate use, then it need not be ready for immediate use.
"Cruiser ready" is a condition developed based on the same philosophy - the officers are expected to already have a loaded pistol on their hip, ready to fire without manipulation, so the time spent charging the longgun and any potential risk of mis-feeding during this manipulation are of minimal or no tactical consequence. The officer's pistol is ready to engage immediate, present threat, and the officer is available to access their longgun. Keeping the longgun completely empty isn't prudent, but the risk of ND/AD or use by unintended users for a relatively unattended, non-primary weapon, without immediate and present threat outweighs the tactical consequence of the charging time. The primary is loaded and ready to fire, the secondary is loaded and ready to be charged.
So my longguns are either loaded mag in/loaded mag ready/tube mag loaded + chamber empty. I'm not handing loose shotshells in a stressful situation if I don't have to - I'm starting from an advantaged mode of preparation and only reverting to fine motor skills upon the failure of primary action to resolve the threat.
Loaded pistol on my nightstand or on my hip. Loaded shotgun or carbine with empty chamber nearby, collocated with chest rig for extra mags, flashlight.
