We see officers pulling phasers out of drawers in their quarters semi-frequently in the 24th C shows.
I remember this happening just once: in "Aquiel", with LaForge having a spare Type 2 lying about. Perhaps he had not yet returned the gun assigned to him for the duration of the investigation?
Elsewhere in TNG, our heroes had to go to the Armory or to dedicated lockers at Sickbay (!) for guns; supposedly, there would have been lockers at Transporter Rooms, too. In DS9, O'Brien had to break into a locker in a cargo hold to attempt suicide. Ops had some sort of an unseen supply of both Bajoran and Starfleet hand weapons, but that's hardly surprising.
Indeed, every crewmember may have a storage locker or drawer at their disposal for phaser storage.
"Starship Mine" suggests that not even Captain Picard had a weapon in his quarters. But the capacity to safely store a weapon there at least temporarily might well exist.
Or it could be unnecessary, because while shipboard, all phasers can be remotely commanded not to fire - see "A Matter of Time". They can probably also be commanded to go to stun mode, or even to fire...
The endless war that (*) wanted the crew to fight, wouldn't really work if there were no weapons available. So (*) probably unlocked the armory so everyone could get in.
Well, our Starfleet heroes would have had the clearance to open the lock by themselves - and the Klingons got their weapons from a separate supply, apparently, one that need not have been an armory to begin with. The thing would have seen to there being an alternate supply, possibly in the galley or the utensils storage room...
Who invented * to signify the beast, BTW? I first saw it used in that Tales of the Dominion War story.
