You just stepped out of Vault 111. The sun is blinding, your spouse is dead, and the world is a literal radioactive dumpster fire. What’s the first thing you reach for? It isn't a Fat Man or some experimental plasma rifle. It’s that chunky, reliable, slightly oversized hunk of pre-war steel known as the Fallout 4 10mm pistol.
Most players treat it like a starter tool. They toss it into a workbench the moment they find a hunting rifle or a combat shotgun. That is a massive mistake. Honestly, if you know what you’re doing with the weapon workbench, this sidearm can carry you from the Red Rocket truck stop all the way to the final showdown at the Institute. It's the Swiss Army knife of the Commonwealth.
The Versatility of the Fallout 4 10mm Pistol
The beauty of this gun lies in its bones. Unlike the pipe pistols that look like they were slapped together by a caffeinated toddler, the 10mm is a professional firearm. It’s modular. You can transform it from a rapid-fire lead hose into a silent assassin’s tool with just a few perks in Gun Nut.
I’ve seen people complain about the damage fall-off in late-game scenarios. Sure, it’s not hitting like a Gauss Rifle. But consider the fire rate. If you slap an Advanced Receiver on that thing, you're looking at a weapon that spits out damage faster than most enemies can react to. It’s about the economy of movement.
Why Weight Matters in Survival Mode
If you're playing on Survival Mode, every pound counts. You can't just carry a mini-gun and a missile launcher because you'll be overencumbered before you even hit Concord. The Fallout 4 10mm pistol is the king of the "weight-to-utility" ratio.
A fully kitted-out 10mm weighs significantly less than a combat rifle. This leaves room for more stimpaks, more purified water, and more junk for your settlements. It’s the pragmatic choice. Some might call it boring. I call it staying alive.
The Best Legendary Effects to Look Out For
We need to talk about RNG. Getting a lucky drop can turn this pistol from a "good backup" into "the hand of god."

The Explosive prefix is the obvious favorite. Each bullet creates a small explosion on impact. Because the 10mm has such a high rate of fire, you can essentially stun-lock a Deathclaw by breaking its legs in seconds. Just don't use it in close quarters, or you'll blow your own limbs off. I've done it. It’s embarrassing.
Then there’s the Wounding effect. This is arguably better for high-health bosses like Mirelurk Queens. It adds bleed damage that stacks. You don't even need to aim for the head. Just pepper them with 10 rounds and watch their health bar melt away while you hide behind a tree.
Don't overlook Instigating if you’re a stealth player. Double damage if the target is at full health? Combined with the Ninja perk and a suppressor, you’re basically a wasteland ghost. You drop Raiders before they even realize their buddy's head just turned into a red mist.
Customization: Making it Your Own
Most players just click the "highest damage" option and move on. That’s a rookie move. You have to balance the sights. A Long Barrel increases your range, but it makes the gun kick like a mule if you're firing rapidly.
I personally prefer the Sharpshooter’s Grip. It gives you better recoil control, which is vital when you're trying to keep your sights on a sprinting Ghoul. And the sights? Always go for the Reflex Sight. The iron sights on the 10mm are, frankly, terrible. They take up too much of the screen. The Reflex Sight gives you a clear window, making those snap-shots much easier.
The Silencer Trade-off
There is a myth that putting a silencer on the Fallout 4 10mm pistol is always the right move. It’s not. While it's great for the Sandman perk bonus, it kills your range. If you find yourself fighting in the open fields of the Glowing Sea, that suppressor is just a weight. Sometimes, you want the muzzle brake for that extra stability.
Comparing the 10mm to the Deliverer
You can’t talk about the 10mm without mentioning its sleek cousin: The Deliverer. You get it from the Railroad. It uses the same ammo, it’s quieter, and it’s incredible in VATS.

Is it better? Maybe.
But the standard 10mm has one thing the Deliverer doesn't: accessibility. You find 10mm pistols everywhere. You can find them on raiders, in safes, and tucked away in desks. This means you can have different versions of the gun for different situations. One for ghouls, one for humans, and one for robots.
The Deliverer is a specialist tool. The Fallout 4 10mm pistol is a generalist masterpiece.
VATS and Action Points
If your character build leans heavily into Agility and Luck, this pistol is your best friend. The Action Point cost per shot is incredibly low. You can queue up ten, twelve, even fifteen shots in a single VATS cycle.
Combine this with the Concentrated Fire perk. Every shot on the same body part increases your accuracy. By the time you get to the fifth bullet, you have a 95% chance to hit a fly from a hundred yards away. It feels like cheating. Honestly, it kind of is.
Logistics: Finding Ammo
Early game, ammo is scarce. You’re scrounging for .38 rounds just to stay in the fight. But 10mm ammo becomes plentiful very quickly.
Check the yellow ammo crates. Trade with Trashcan Carla. If you take the Scrounger perk, you will literally never run out. I’ve ended playthroughs with over 5,000 rounds of 10mm ammo just sitting in my inventory because the game throws it at you.
Hidden Mechanics and Quirks
Did you know the reload animation for the 10mm is one of the fastest in the game? It sounds like a small detail, but when a Super Mutant Suicider is sprinting at you with a nuclear football, those extra milliseconds matter.
Also, the bash damage. Look, nobody uses the bayonet. It looks cool, but it ruins your range and accuracy. If you're close enough to stab someone with a pistol bayonet, you've already messed up. Just use the bash button to stagger them and then put a bullet in their chin.
Practical Steps for Your Next Playthrough
If you're starting a new game today, don't ignore the first gun you find. Here is how you should handle it:
- Invest in Gun Nut early. Level two is where the 10mm really starts to shine with the Hardened Piercing Auto Receiver.
- Scavenge for Oil and Screws. These are the bottleneck materials for pistol mods. Keep an eye out for desk fans and lighters.
- Find the "wastelander's" version. Some vendors sell 10mm pistols with pre-installed mods. Buying a gun just to strip the "Powerful Receiver" off it is often cheaper than crafting it yourself if your perks are low.
- Specialist builds. If you're going for a Gunslinger build, rush to the Hubris Comics building early. You can find the Grognak the Barbarian magazines nearby, but more importantly, it's a great place to test your 10mm's crowd-control capabilities against Ghouls.
- The Quest for Legendary versions. Farm the legendary enemies in the Forest area or near the USAF Satellite Station Olivia. A "Never Ending" 10mm (which removes the need to reload) is a total game-changer for boss fights.
The Fallout 4 10mm pistol isn't just a "starter" gun. It’s a reliable partner. It’s the weapon that sits on your hip through the mud of the marshes and the neon glow of Diamond City. It might not be the flashiest tool in the wasteland, but when the chips are down and the Radroaches are biting, it’s the only thing you can truly trust.
Get to a workbench. Upgrade that receiver. Clear the Commonwealth.
