You’re standing in front of a Bug Hole. It’s orange, it’s glowing, and it’s about to vomit a hundred Scavengers right onto your cape. You reach for your grenades. Empty. You check your Support Weapon. It's a Quasar Cannon, great for Behemoths, useless for closing holes unless you want to wait for a cooldown that feels like an eternity. This is exactly why the GP-31 Grenade Pistol Helldivers 2 players keep in their secondary slot isn't just a sidearm; it’s a lifestyle choice.
Most people see a secondary and think "panic button." They want something that sprays bullets when a Hunter gets too close. But the Grenade Pistol? It’s different. It’s basically a handheld demolition kit that happens to fit in a holster. If you aren't carrying this thing, you’re essentially playing the game on a self-imposed "hard mode" that nobody asked for.
Honestly, the sheer utility of having eight (well, now fewer if you aren't careful with ammo) explosive rounds in your pocket changes how you build your entire character. It frees you up. You can finally take those Stun Grenades you’ve been eyeing. You know the ones—the grenades that make Chargers stand still so you can headshot them, but usually leave you with no way to blow up Fabricators. The Grenade Pistol solves that. It’s the bridge between "I can kill things" and "I can actually finish the objective."
The Math of Destruction: Why One Shot Matters
Let’s talk numbers, but not the boring kind. The GP-31 isn't a crowd-clearer. If you fire this into a pack of Pouncers, you might kill three of them, but you’ve wasted a precious round. It’s a precision tool. It deals significant splash damage, sure, but its real power lies in its ability to seal spawn points from a distance.
Before the developers at Arrowhead started tweaking the ammo economy, you could find yourself swimming in grenades. Now? You’ve got to be a bit more surgical. You get two rounds back from a standard ammo box and a full refill from a Resupply. It’s a fair trade. It forces you to actually aim. You can't just spam shots at a Scout Strider’s face and hope for the best. Well, you can, but you’ll be clicking empty air three minutes into a 40-minute mission.
The muzzle velocity is also something you’ve gotta learn. It’s got a bit of a loop to it. It’s not a sniper rifle. If you’re trying to hit a Fabricator vent from 50 meters away, you need to aim a bit higher than you think. It feels heavy. It feels mechanical. When that shell slides into the chamber, there’s a distinct "clink" that just screams managed democracy.
Fabricators, Bug Holes, and Tactical Flexibility
The biggest mistake I see Helldivers make is using the Grenade Pistol as a primary weapon. It’s not. It’s a key. It’s a key that unlocks buildings.

On the Automaton front, this thing is a godsend. Everyone knows the pain of trying to toss a standard HE grenade into a Fabricator vent while heavy devastators are pinning you down. You miss. The grenade bounces off the flap. You die. With the GP-31 Grenade Pistol Helldivers 2 veterans know they can just snap-aim at the vent or even the open door if a bot is walking out. Boom. Objective complete.
And don't even get me started on the Terminid side of things. Closing a heavy nest used to require a supply pack or a specific support weapon like the Autocannon. Now? You can run a Flamethrower for the vibes and still close every hole in the vicinity without breaking a sweat. It allows for "The Specialist" builds. You can be the guy who handles the big stuff because your secondary handles the infrastructure.
Why Stun Grenades Changed Everything
You can't talk about this pistol without talking about the G-23 Stun Grenade. In the current meta, Stun Grenades are arguably the best utility item in the game. They stop a charging Hulk in its tracks. They turn a chaotic swarm into a shooting gallery. But if you take Stuns, you lose your ability to destroy objectives.
This is the exact "problem" the Grenade Pistol was born to solve.
- Equipping Stun Grenades for crowd control.
- Using the Grenade Pistol for hole-closing and fabricator-popping.
- Carrying a high-damage primary like the Sickle or the Breaker Incendiary.
- Profit.
It’s a specific loop. It’s efficient. It makes you feel like a one-man army rather than a guy who forgot his toolkit at home.
The Ammo Scarcity Reality Check
We have to address the elephant in the room: the ammo nerf. Earlier in the game's life cycle, the Grenade Pistol was a bit too "braindead." You had plenty of shots, and finding more was easy. Arrowhead changed that because they wanted choices to matter.

Now, if you miss a shot, you feel it in your soul.
You find yourself scouring the map for those little brown crates. You start pinging Resupply pods like your life depends on it—because it does. This change actually made the weapon more rewarding. It turned it from a "spam-tube" into a "clutch-maker." When you’re the last one alive and there’s one hole left in a Stalker nest, that last shell in your GP-31 is the most important thing in the universe.
Comparison to Other Secondaries
Is it better than the Redeemer? Maybe. The Redeemer is great for when a Hunter is literally licking your face. It’s a "get off me" tool. The Grenade Pistol won't save you at point-blank range; in fact, it’ll probably kill you along with the bug.
Then there’s the Senator. The big iron. It’s cool, it’s got medium armor penetration, and it makes you feel like a space cowboy. But a Senator can't blow up a mortar Emplacement. It can't stop a dropship's occupants from being a problem before they even land.
Basically, if you’re playing for efficiency, the Grenade Pistol is the king. If you’re playing for style, maybe you pick the revolver. But in Helldive difficulty (Level 9 or 10), style doesn't close holes. Explosives do.
Navigating the Learning Curve
You're going to blow yourself up. Let's just get that out of the way. The proximity required for the shell to arm is small, but if you hit a scavenger that jumped in front of you, you’re going back to the reinforcement screen.

The arc is the other thing. Practice in the trivial missions. See how the shell drops over distance. Once you master the "lob," you can take out spore spewers and shrieker nests (if you have enough ammo and patience) from distances that keep you safe from the chaos.
Expert Tips for the GP-31:
- The Vent Trick: For Automaton Fabricators, you don't need to be perfectly level. If you're above the vent, you can aim at the back plate of the chimney. The splash damage often triggers the explosion.
- Shield Devastators: Hit the ground at their feet. The explosion ignores their shield and staggers them, opening them up for a primary weapon follow-up.
- Berserkers: Don't waste shots here. They have too much HP. Use your primary.
- Strider Pods: A single shot to the "hip" or the top of the walker usually deletes the pilot.
What Most People Get Wrong
People think this is a weapon. It’s actually a gadget.
If you view the GP-31 Grenade Pistol Helldivers 2 as a tool for environmental interaction rather than a weapon for combat, your survival rate will skyrocket. It’s for the illegal broadcast towers. It’s for the shipping containers buried in the map that hold Medals and Super Credits. It’s for the obstacles that stand between you and the extraction shuttle.
The nuance is in the restraint. The best Grenade Pistol users are the ones who rarely fire it. They save those six or eight rounds for the moments where nothing else will work. They are the ones who don't need to call down a Precision Strike on a rogue research station because they can just lob a shell through the window.
The Future of the Sidearm Meta
As the Galactic War evolves and the Illuminate (eventually) show their faces, the value of the Grenade Pistol might shift. Energy shields could change the math. But for now, as long as there are holes to be plugged and factories to be leveled, this weapon remains the undisputed heavyweight champion of the secondary slot.
It’s about the freedom of the build. It’s about not being tethered to an explosive primary like the Eruptor or the Crossbow. It’s about being able to take the tools you want because you’ve already packed the tools you need.
If you haven't unlocked it yet in the Democratic Detonation Warbond, make it your priority. It’s 1,000 Super Credits well spent. It’s more than a gun; it’s the piece of the puzzle that makes the rest of your loadout actually make sense.
Actionable Next Steps for Helldivers
- Audit your current loadout: If you are carrying Impact Grenades and a Grenade Pistol, you’re doubling up on the same utility. Switch to Stun Grenades immediately to maximize your tactical options.
- Practice the "Arc": Spend one solo mission on a low difficulty just shooting at rocks from different distances. Learning the drop of the GP-31 shell is the difference between a wasted shot and a destroyed objective.
- Trigger Discipline: Train yourself to never use the pistol on single infantry units. If you find yourself using it because you forgot to reload your primary, you’re practicing bad habits that will kill you on higher difficulties.
- Map Awareness: Start looking for "explosive opportunities." Notice how many secondary objectives (like fuel tanks or ammo caches) can be cleared with a single shell from your secondary, saving your Stratagems for the real fights.
Success in Helldivers 2 isn't about who has the biggest gun; it's about who has the right tool for the job at the exact moment the job needs doing. The Grenade Pistol is almost always that tool. Get comfortable with it, respect its ammo limits, and stop blowing yourself up. Liberty depends on it.
