The firearm has mechanisms that enable it to fire more quickly. When the wielder uses this weapon to attack as an action, bonus action, or reaction, it may attack twice, but the second attack has disadvantage. Creatures with the Extra Attack or Multiattack feature do not suffer disadvantage on the second attack.
