Captain Panaka, always mindful of potential dangers, has personally
supervised the Queen's training in the martial arts, including regular
pistol practice at a secure palace firing range. The royal pistol was
specially designed for Amidala and her handmaidens, its size and
weight making it a perfect and natural extension of the hand. The
Queen's entourage, from the Theed Palace guards to her personal
handmaidens, are also trained by Panaka to add to the Queen's safety.

marksmanship and her own weaponry to defend herself in a crisis. (from the Official site: www.starwars.com
