Another example would be a pistol with a built-in suppressor.
Since this handgun would be classified as a dangerous ordnance because of the suppressor, it's not a 'handgun other than a dangerous ordnance'.
Yet another example is a Glock 18.
Federal laws notwithstanding, because the Glock 18 is select-fire (full-auto capable), it is a dangerous ordnance. That means it's not a 'handgun other than a dangerous ordnance'.
