I, like most I would imagine, have seen many shooters at the range accidentally and unknowingly bump the mag release when preparing to fire off a shot, rendering the pistol a useless brick instead. I would rather have at least that one chambered round function, than expecting a shot and nothing happens until you lock mag back into place. I think the scenario of mag accidently dropping a little would occur much more frequent than the need to purposely drop the mag under duress.
