A firearm is a a normally tubular weapon or other device designed to discharge projectiles or other material.


A flintlock (フリントロック Furintorokku?) is a type of gun ignition mechanism that was first introduced in about 1630. It was a revolutionary design that replaced the firearm-ignition technologies at the time, such as the matchlock and wheel-lock.

Flintlock Infobox

An explanation for a flintlock's mechanism.

The flintlock was renowned for becoming next to useless in the rain, but was a great improvement over the matchlock which required a lit slow-burning match cord that was impossible to keep lit in the rain. In damp weather, shooters would keep a cover of some sort over the lock to keep it dry until use. Most flintlocks had only one barrel and had to be reloaded from the muzzle after each discharge. Civilians typically used a powder-horn and ball bag to reload after each shot. In military use, soldiers used preload paper cartridges that contained both a measure of gunpowder and a ball (bullet) to speed up reloading. Due to the length of time it took to reload, most stationary gunmen using the weapon would carry several spares (often pistols) on them so they did not have to waste time reloading after each round. However, despite its downfalls, the flintlock was a favorite military weapon.


A musket (?) was typically a military version of a flintlock. It was a smooth bore weapon into the early 19th century. Like all muzzle-loaders, it required a tedious reload, however cartridges (a paper tube pre-filled with powder and ball) sped up the process. A trained soldier could fire from 3 to 5 times a minute and carried several dozen cartridges in specially designed containers slung over the shoulder or on a belt about the waist. The flintlock musket was in use from colonial times into the first half of the 19th century. A rifled musket was a later military firearm that had spiral grooves in the barrel. The percussion cap rifled musket was the standard issue military firearm by the mid 19th century.


Marineford's Defense Cannons

A defense cannon used in Marineford.

A cannon (?) is an often large, heavy piece of artillery that uses explosive material, such as gunpowder, to launch projectiles of considerable size compared to bullets, such as cannonballs or bombshells. Cannons can be mobile or stationary, and may vary in size, sometimes requiring the operation of more than one individual to work properly. Cannons predated portable firearms for several years, having been an indispensable weapon in military and naval warfare through centuries due to their power and range.

One PieceEdit

The flintlock is the main gun type seen in the series. They are much more advanced than the traditional flintlocks of real life, in that they do not suffer the same reloading time and limited rounds as found in the real life versions. Most of the flintlock weaponry in One Piece are also semi-automatic, something only found on a few exotic multi-barrelled volley gun designs in real life. Both Yasopp and Lucky Roux, along with many background characters, have been seen using these type of guns. The guns, however, still fire small, round, ball-like bullets like those used by the traditional guns until the last couple of centuries.

Cannons also see widespread use throughout the series, as practically every ship is equipped with at least one cannon as a defensive measure, be they Pirate or Marine ships. Marine cannons, however, appear to be more technologically advanced as they can function like gun turrets, allowing for better aiming. Cannons are also commonly found in other military structures such as Marineford.

Types of FlintlocksEdit

Because of the more advanced structures of the standard flintlock, there are other models and ammunition developed for use. Also, even standard flintlocks may be customized in physical appearance to suit one's motif.

Other Types of FirearmsEdit

Aside from the standard flintlocks and muskets (along with their modified variants), there are other type of guns introduced in the series, though they appear rarer than the flintlock. Most of their designs are based off of the flintlocks, bearing the appearance and mechanism that fits the older times.

Translation and Dub IssuesEdit

4Kids reaction to the presence of the guns is to color them green (or blue in a few cases), remove them, or turn them into something else (hammer-gun, arrows, Super Soakers, or cork gun). However, it should be noted this is a common edit with all guns, not simply flintlocks.
