"Routine" is the operative word here. Start by removing ALL ammunition at least to a different room. Double check. Triple check. No ammo in gun, in room, or on person. Use a special "dry practice only" target, kept out of sight when not in use. Only bring the target out after clearing the room of ammo. Put it away at the end of the session, before accessing any ammunition.
I know that it sounds excessively careful, but a LOT of negligent discharges happen immediately before/after a "dry practice" session. How can that be?
