Honestly, if you grew up playing PC games in the 2000s or 2010s, that specific "thwack-ping" sound is basically burned into your brain. You know the one. You’re standing on gm_construct, looking at a wooden crate, and suddenly it’s welded to a bathtub and flying into the stratosphere at Mach 5. That is the magic of the Garry’s Mod tool gun.
It’s just a digital toy. But for millions of us, it was the first time we felt like we actually owned the game world instead of just walking through it.

The Secret History of a Modding Icon
Most people assume the tool gun was always there, but the early days of GMod were way more chaotic. In the very first versions back in 2004, Garry Newman didn't even have a dedicated tool. You had to use a modified RPG or the Half-Life 2 pistol to spawn stuff.
The physical model we all love—the one that looks like a Colt Python got into a fight with a RadioShack—wasn't even made by Garry. It was designed by a modder named Dave Hunt, known online as Dav0r. Sadly, Dave passed away in 2023, but his legacy lives on every time someone pulls that trigger. He took a basic revolver and slapped an LCD screen, a bunch of messy ribbon cables, and a battery onto it.
It looks janky. It looks like it was built in a basement. And that’s exactly why it works. It fits the "I'm just messing around with code" vibe of the game perfectly.
Why It’s Better Than a Real Gun
In any other game, a gun is for killing. In GMod, the tool gun is for everything else. It’s a paintbrush, a welder, a rope-maker, and a facial-expression-contorter all in one.

When you look at the screen on the back of the model, it actually changes based on what tool you have selected. That was high-tech for 2006! It grounded the sandbox experience. You weren't just clicking a menu; you were using a physical device to rewire the laws of physics.
How to Actually Use the Garry’s Mod Tool Gun Without Exploding Your PC
If you’re new to the game, the menu can be a nightmare. You hit "Q," and suddenly there are fifty tabs on the right side of your screen.
Weld is your best friend. It’s the glue of the GMod universe. If you want to build a car, you weld the wheels to the chassis. Simple, right? But then you have Axis and Ball Socket, which allow things to rotate. If you use Weld when you should have used Axis, your car is just a very expensive paperweight that jitters until it clips through the floor.
- The Remover Tool: Left-click deletes things. Right-click deletes things and their friends (everything connected to them). Be careful with the right-click. I've seen people accidentally delete entire bases because they missed a tiny prop.
- The Material Tool: This is how you make a shipping container look like it's made of glass or glowing neon. It’s purely aesthetic, but it’s essential for those "aesthetic" screenshots.
- The Thruster: This is where the physics engine starts to sweat. You attach these to an object, assign a key, and suddenly you have a rocket.
Dealing With the "Prop Crate" Chaos
We've all been there. You're trying to build a simple house, and you accidentally weld two massive props inside each other. The Source engine hates this. It starts making a sound like a Geiger counter on steroids. This is called "prop collision," and if you don't fix it with the No-Collide tool, your creation will eventually vibrate until it gains sentience and flies into the sun.
Addons That Make the Tool Gun God-Tier
The base tools are fine, but the community has been perfecting this stuff for over two decades. If you aren't using these, you’re playing on hard mode.
- Precision Tool: The standard Weld is kinda sloppy. Precision let’s you move objects by the millimeter and snap them to corners.
- SmartSnap: It puts a grid on props so you can hit the exact center every time.
- Wiremod: This is basically a computer science degree inside a video game. You can use the tool gun to place microchips, screens, and sensors. You can literally build a working calculator or a self-guided missile if you have enough patience.
- Advanced Duplicator 2: Because nobody wants to rebuild their 500-prop space station from scratch every time the server restarts.
The Cultural Impact: From YouTube to VR
It's weird to think that the Garry’s Mod tool gun influenced modern gaming so much. Look at the "Build Mode" in games like Fallout 4 or No Man’s Sky. They all owe a debt to the clunky UI of GMod. Even the way we interact with VR menus feels a lot like pointing that old 3D-modeled revolver at a floating screen.
It’s also the reason why YouTube "Machinima" became a thing. Without the Face Poser tool, we wouldn't have the bizarre, distorted faces of the early GMod era that paved the way for modern internet humor. It turned every player into a director.
Practical Steps for Mastering the Tool
If you want to actually get good at building, stop just spawning stuff and start learning the constraints.
- Start with Parent-Multi: This is an addon that "parents" objects together without the physics lag of 1,000 welds.
- Learn the R key: In almost every tool, pressing R while looking at a prop will "reset" or "undo" that specific tool's effect on that prop. It saves so much time compared to hitting Ctrl-Z.
- Use the Search Bar: Seriously. Don't scroll through the list. Type "Weld" or "Rope." Your eyes will thank you.
The tool gun is the ultimate "what if" machine. It’s been around for over 20 years, and even in 2026, there is still nothing that feels quite as satisfying as that initial "click" when you finally get a contraption to work. Just... maybe stay away from the "Nuke" addons until you've saved your game.
Go download the Precision Tool from the Steam Workshop immediately if you haven't already; it's the single biggest quality-of-life upgrade for any builder. Once you have that, try building a simple door with a Hinge and a Numpad Input to get a feel for how constraints and triggers interact without the complexity of Wiremod.
