Trope-a-Day: Dramatic Gun Cock

Dramatic Gun Cock: Modern personal weapons don’t actually need cocking (just flip the arming switch to Unsafe, and you’re done, to the accompaniment of no more than a little electrical hum or capacitor-charging whine).  On the other hand, since they fold up very nicely into a more convenient form-factor for storage and transportation, you can do all the dramatic unfoldings (push the button and let the springs, etc., do the rest) that you like.
