The Smith & Wesson Bodyguard 2.0 basically changed the conversation about pocket pistols overnight. It’s thin. It’s surprisingly shootable. But for a lot of us who can't leave well enough alone, the stock configuration is just the starting line. Now everyone's hunting for a Bodyguard 2.0 threaded barrel. Why? Because the idea of a suppressed pocket gun is hilarious and awesome, but also because of the practical gains in velocity and compensator compatibility.
You’ve probably seen the forum threads. People are asking if a longer barrel ruins the "pocket" part of a pocket pistol. Honestly, it depends on your holster. If you're rocking a sticky holster in loose jeans, that extra half-inch of steel might poke through. But if you’re looking to squeeze every bit of performance out of the .380 ACP cartridge, adding a threaded option is the most logical move you can make.
Why People Are Scrambling for the Bodyguard 2.0 Threaded Barrel
The .380 ACP gets a bad rap. People call it "9mm Short" like it’s a bad thing. However, barrel length matters immensely with this caliber. A standard Bodyguard 2.0 has a 2.75-inch barrel. That is tiny. When you move to a Bodyguard 2.0 threaded barrel, you’re usually gaining about 0.4 to 0.5 inches of effective rifling before the threads start.
That extra length matters for expansion. Most defensive .380 loads, like the Hornady Critical Defense or the Federal Hydra-Shok Deep, are engineered to expand at specific velocities. If your barrel is too short, the bullet might not go fast enough to open up. It just turns into a small, expensive FMJ. By adding a threaded barrel, you’re giving the powder just a millisecond longer to burn. This translates to higher muzzle energy. It's a small margin, but in a self-defense situation, margins are everything.
Then there's the "cool factor." Let’s be real.
Putting a suppressor on a gun this small looks like something out of a 1960s spy movie. While a Rugged Obsidian 9 or a SilencerCo Omega 9K might look massive on a Bodyguard, it makes for a very quiet range day. More importantly, it allows for the use of a compensator. A small, single-port comp on the end of a Bodyguard 2.0 threaded barrel makes the snappy .380 recoil feel like a .22 LR. It keeps the muzzle flat. You can get back on target faster. For a gun that weighs almost nothing, taming that flip is a huge win.
The Technical Reality of the Drop-In Fit
Most of these barrels are marketed as "drop-in." In the world of Smith & Wesson, that’s usually true. The M&P series, which the Bodyguard 2.0 draws its DNA from, has pretty generous tolerances. You shouldn't need a gunsmith. You just field strip the gun, pop the old barrel out, and slide the new one in.
But watch out for the feed ramps.
A high-quality Bodyguard 2.0 threaded barrel should have a polished feed ramp. The .380 round can be finicky with flat-nosed hollow points. If the ramp isn't smooth, you’ll get "failure to feed" issues that’ll drive you crazy. Brands like Faxon or True Precision (if they follow their usual M&P patterns) usually handle this well.
The locking block interface is the other critical spot. The Bodyguard 2.0 uses a tilting barrel action. If the geometry of the lug on your new threaded barrel is off by even a hair, the slide won't go into battery. It'll feel "crunchy." If you install a new barrel and the slide doesn't move like butter, don't force it. That’s how you gall the frame.
Accuracy Gains and Sight Radius
Does a longer barrel make the gun more accurate?
Strictly speaking, no. Mechanical accuracy comes from the consistency of the lock-up. However, a threaded barrel often has a tighter crown than a mass-produced factory barrel. A "target crown" protects the rifling where the bullet exits. If that exit point is perfectly uniform, the gas disperses evenly behind the bullet. This prevents the "wobble" that can happen with cheaper barrels.
You aren't going to be hitting dimes at 50 yards with a Bodyguard 2.0 threaded barrel. It’s still a pocket gun. But at 7 to 10 yards? You might see your groups shrink from three inches to two. It builds confidence.
Thread Pitch and Accessories
Most .380 barrels use a 1/2x28 thread pitch. This is the industry standard. It’s the same as your AR-15 (though please, for the love of all things holy, do not put a 5.56 muzzle brake on your .380).
- Thread Protectors: Never shoot without one if a suppressor isn't attached. The threads are delicate. If you ding them against a barricade or a rock, you aren't getting a silencer on there ever again.
- O-Rings: Use a high-temp Viton O-ring. It keeps the thread protector from unscrewing itself while you shoot. There's nothing more annoying than having to tighten your barrel every five rounds.
- Compensators: Look for "micro" comps. Large ones will make the gun front-heavy and might actually cause cycling issues because they add too much weight to the reciprocating mass.
Addressing the Reliability Myth
Some people claim that adding a Bodyguard 2.0 threaded barrel makes the gun less reliable. This is usually a misunderstanding of physics. A threaded barrel itself doesn't hurt reliability. It's what you put on the threads that does.
If you hang a heavy suppressor off the end, you’re adding weight to a barrel that needs to tilt to unlock. This can slow down the action. This is why "Boosters" or Nielsen devices exist in suppressors. They use a spring to momentarily uncouple the weight of the silencer from the barrel, allowing the gun to cycle. If you're running a Bodyguard 2.0 suppressed, you need a lightweight can or a very well-tuned booster.
If you’re just running the barrel with a thread protector? It should be just as reliable as the factory part, provided the manufacturer knew what they were doing with the dimensions.
What Most People Get Wrong About Pocket Carry
The biggest misconception is that a threaded barrel makes the gun "un-carryable."
Think about it.
The threaded portion adds maybe half an inch to the overall length. Most holster manufacturers like Vedder or Tulster leave the bottom of their holsters open. This is called an "open-ended" or "pass-through" design. Your Bodyguard 2.0 threaded barrel will just poke out the bottom. Since that part of the gun is pointing toward the ground inside your pants, it doesn't affect the "printing" of the grip, which is what actually gives away a concealed gun.
The only real downside is comfort. If you carry AIWB (Appendix Inside the Waistband), that extra half-inch might poke your leg when you sit down. If you're a bigger guy, you might not even notice. If you’re skinny, it might be a literal pain in the crotch.
Choosing the Right Material
You’ll usually see two options: 416R Stainless Steel or Carbon Steel.
416R is the gold standard for match barrels. It’s easy to machine and holds up well to the heat of rapid fire. Most Bodyguard 2.0 threaded barrel upgrades will be 416R. Then you have the coatings.
- DLC (Diamond-Like Carbon): This is the best. It’s hard as nails and very slick.
- TiN (Titanium Nitride): That’s the gold stuff. It looks cool, but it can be flashy. Some people love the "gucci gun" look.
- Nitride/Melonite: This is a chemical treatment that hardens the surface. It’s dull black and incredibly durable.
Honestly, for a carry gun, DLC or Nitride is the way to go. You want something low-profile that won't rust if you sweat on it all day.
The Cost-Benefit Analysis
A high-quality threaded barrel for the Bodyguard 2.0 is going to run you anywhere from $140 to $220. That’s nearly half the price of the gun itself. Is it worth it?
If you are a "one gun" person, maybe not. But if you use the Bodyguard as a primary deep-concealment tool, the ability to add a compensator for better control is worth the money. If you’re a suppressor enthusiast, it’s a non-negotiable.
There's also the resale value. Enthusiasts love modified S&W pistols. If you ever decide to sell the gun, having that threaded barrel usually helps it move faster on the secondary market, even if you don't get 100% of your investment back.
Real World Performance
In testing with various .380 loads, the jump from a 2.75" barrel to a 3.25" (threaded equivalent) usually nets about 35-50 feet per second (FPS). It sounds like nothing. But in the world of ballistics, that can be the difference between a hollow point expanding to .50 caliber or failing to expand at all.
I’ve seen it happen with the older Bodyguard models. Short barrels struggle with heavy 90nd 95-grain bullets. The Bodyguard 2.0 threaded barrel gives that bullet just enough "runway" to get up to its design speed.
Actionable Steps for Your Upgrade
If you’re ready to pull the trigger on a Bodyguard 2.0 threaded barrel, don't just buy the first one you see on a random website.

- Check your holster first. Reach down and see if your current holster has a closed bottom. If it does, you’ll need to either heat it up and open it or buy a new one.
- Verify the twist rate. Most .380 barrels are 1:10. This is fine for almost all ammo. If you see something weird like 1:16, keep moving.
- Buy quality ammo for testing. Once the barrel is in, you need to run at least 50 rounds of your "duty" or "carry" ammo through it. Do not trust your life to a new barrel until you’ve confirmed it feeds your specific hollow points.
- Lube the lugs. New barrels have sharp edges. Apply a tiny bit of high-quality gun grease to the top of the barrel hood and the locking lugs for the first 100 rounds. This helps the parts "mate" together without excessive wear.
- Inspect the thread protector. Every time you clean the gun, check the threads. If you see any lead buildup or carbon, use a nylon brush to clean it out. Never use a steel brush on threads; you'll ruin them.
The Smith & Wesson Bodyguard 2.0 is already a fantastic platform. Adding a threaded barrel doesn't fix a "broken" gun—it just unlocks the potential of a tiny one. Whether you want it for the suppressor, the extra velocity, or just because it looks mean, it's a solid upgrade that actually serves a purpose. Just make sure you stay on top of the maintenance and keep those threads protected.
