It is a common firearm in the 18th century, which uses flint or flint pieces as ignition devices. When the trigger is hit by a hammer, sparks are generated, igniting the gunpowder. Ammunition needs to be manually reloaded and loaded through the barrel opening, including gunpowder, pellets, and paper pads. The paper pads provide a sealing effect to ensure that gunpowder and pellets are tightly compressed inside the barrel. In combat, these weapons are usually only used for single shot shooting because the loading method is very slow and there is usually no time to reload. Therefore, soldiers who have fired have to pull out their swords or knives, or if they cannot reload them in time, use pistols as sticks.
