An Archaeotech Pistol was an ancient sidearm dating back to the Age of Technology. This type of pistol was capable of firing a variety of projectiles, be they micro-atomic munitions or searing directed energy kill-rays that drew power from a planet's magnetosphere. Archaeotech Pistols often served as the sidearms of high-ranking Imperial nobles and Imperial Army and Space Marine commanders during the Great Crusade and Horus Heresy eras.
