All 15 Guns in Grand Piece Online

Updated on October 30, 2026 (10 days ago)

Guns are the ranged weapons in Grand Piece Online, the pirate game on Roblox. Instead of getting up close with a sword, you can shoot at enemies from a distance, which helps when you want to hit something before it reaches you. Guns are one of several ways to fight, alongside swords, Fighting Styles and Devil Fruits. A few are easy to buy early on, while others come from bosses or can only be traded for.

What Guns Do in Grand Piece Online

Once a gun is equipped, the left mouse button is what fires it. Each gun has its own strengths at different distances, so some are built for close fights while others reach further. It helps to know which one fits the fight in front of you.

Guns work best as one tool among several, so it's smart to keep a sword or another melee weapon ready. When an enemy gets close and a gun stops being the best choice, having a melee weapon on hand means you're never stuck.

How to Get Guns in GPO

Most guns aren't sold in shops. Lily in the Town of Beginnings sells the Pistol and Rifle for Peli, which makes them the easiest guns to get when you're starting out. Most of the others come from bosses: Malcolm in Malcolm's Lair drops the Shotgun, Lucid on Sandora Island drops the Bazooka, and Bruno in Skypiea drops the Burn Bazooka.

Boss drops are random, so it can take several fights before the gun you want shows up. Don't be discouraged if your first few runs come up empty.

Guns You Can Only Get by Trading

Some guns came from past events or reward tracks, leaving trading as a way to get existing copies. The Stark Gun is one of these. Prestige versions of some guns and a few event guns are also trade-only.

The Inferno Rocket Blade is a special case. It works as both a sword and a gun, and because it's seasonal, it only shows up for a limited time. Existing copies can be traded.

Best Early Guns in GPO: Pistol and Rifle

The Pistol and Rifle matter most in the early game, while you're still building up your character. The Pistol is the cheaper of the two. It reloads quickly and is good at drawing enemies toward you while you level up, but its damage is low, so think of it as a starter gun.

The Rifle is a straightforward upgrade over the Pistol. It hits harder and does the same job of drawing enemies in, so it's the one to aim for once you can afford it.

Shotgun, Bazooka and Burn Bazooka: When Each Gun Shines

The Shotgun fires a spread of shots in a cone, so it hits hardest when the enemy is close and loses power the farther away they are. The Bazooka is an explosive weapon, so its blast can catch enemies near the one you aim at. The Burn Bazooka is a charged gun, built for planned shots rather than quick ones.

Choose based on how close you expect to fight and whether you have time to set up a shot.

Gun Mastery in Grand Piece Online

Gun Mastery is the stat that tracks how well you handle guns. It's tied to the damage your guns can deal, so it's worth knowing about once you start relying on one.

Aiming and Charging Guns in GPO Fights

Aim for the head when you can. With the Pistol and Rifle, a headshot doubles the damage, so a clean hit is worth the extra effort.

The Burn Bazooka needs you to hold the left mouse button to charge before it fires. While it's charging, you can't use Haki and your movement is limited. Start the charge in a calm moment, not in the middle of a chase.

FAQ

Q.

Does the Bazooka push you back when it fires?

Yes. Its recoil causes a slight knockback, so you'll be nudged a little each time you fire it.

Q.

Is the Shotgun slower to use than the Pistol or Rifle?

It has a slower draw speed, which means it takes a little longer to get ready to fire. Its reload time is about the same as theirs, though.

Q.

Can you land headshots with the Shotgun?

Yes. Headshots are possible with the Shotgun even at lower Gun Mastery.

Q.

What does the Burn Bazooka do when it fires?

Once it's fully charged, it fires a powerful blue explosion.
