It is basically a force continuum question. It is not really stupid.
One might easily pose the question as:
If I come across someone in my house and I have my gun at the ready - should I challenge them and order them not to move as I have a gun or just shoot them immediately?
The technical aspect of a gun that is not immediately available to use as a lethal weapon is a naive question but that of trying to deal with a situation without immediate use of deadly force is not.
