So what does "maintain continuous possession" mean ?

If I leave them at home when I go to work, have I relinquished my possession of them ?

Do I have to prevent any other person's access to them by, perhaps, locking them in a safe with me being the only one to know the combination ?

EX: I understand (and maybe incorrectly...someone jump in if I am off base) that there may be circumstances when a convicted felon OWNS a weapon, but is not in possession of it. Such as if he/she owns several weapons, serves time, is released and returns home. If he/she owned any weapons, he/she STILL owns those weapons, but cannot POSSESS them. They often have to be given to others or sold by another on the felon's behalf.
