All the pirates, including Long Drong, gain an additional Attack because they are fighting with a pistol in each hand. Since they are festooned with pistols which they shoot off in a hurricane of destruction, all of their attacks are considered to be Strength 4 Armour Piercing pistol shots. The Pirates carry so many pistols that they never need to reload, therefore their pistol bonus is always in action, not only in the first round of combat.
