SMGs are among the most versatile weapons in Borderlands 4, filling the close-to-medium range role with high fire rates and, frequently, strong elemental application. But the best SMG for you is not a fixed name on a list; it is the one that matches your build, your element plan, and the fights you actually take. This guide explains what makes an SMG strong in Borderlands 4 so you can evaluate any one you pick up rather than relying on a ranking that a patch will shuffle.
Because Borderlands 4 is updated regularly, I have kept specific weapon names and exact stats qualitative and focused on the properties that matter. The principles here are cross-checked against the Borderlands Wiki on Fandom, the r/Borderlands4 community, and weapon coverage from IGN, GameRant, and PowerPyx, all checked in October 2026. Confirm any particular legendary SMG's current roll and behavior in-game, since small part and element changes have a large effect on this class.
What makes an SMG strong
SMGs earn their place through sustained damage and elemental application rather than single-shot power. Their high fire rate means they apply elemental effects quickly, which makes element the first thing to evaluate: an SMG with the right element for the enemies you face will dramatically out-damage a higher-base SMG with the wrong one. Matching element to health type, such as the correct element against shields or armor, often matters more than any raw number on the card.
Handling is the second pillar. Because SMGs rely on sustained fire, magazine size, reload speed, recoil, and accuracy decide whether you can actually keep damage on target. An SMG with a huge damage number but a tiny magazine and punishing recoil can feel worse in practice than a steadier weapon you can control through a whole engagement. Favor SMGs you can keep on target, because uptime is where this class does its work.
The third consideration is the special effect on legendaries. Many legendary SMGs carry a gimmick such as bonus projectiles, a unique firing mode, ricochets, or a conditional damage boost. The best effects are the ones that fit your build and trigger in your normal flow of combat, not the flashiest ones. A well-rolled SMG with the right element and solid handling can easily beat a gimmicky legendary whose effect pulls against your build.
Manufacturers and their SMG personalities
Each manufacturer gives its SMGs a distinct feel, and knowing those personalities narrows your search. Maliwan SMGs are traditionally the go-to for elemental play, often firing pure elemental damage and excelling at stripping shields and applying status effects, which makes them a natural fit for any build centered on elements. If your plan is to lean on a damage type, a Maliwan-style SMG is usually the first place to look.
Other manufacturers trade elemental focus for different strengths. Some offer high raw fire rates and large magazines for relentless sustained damage, some emphasize accuracy and controllability for medium-range work, and some add explosive or unusual projectile behavior. There is no single best manufacturer; there is a best one for your build and the role you need the SMG to fill. A character wanting raw bullet-hose pressure will prefer a different maker than one wanting precise elemental application.
When comparing two SMGs, do not just read the damage card. Fire both through a sustained engagement and feel how well you can keep the stream on target and how quickly the element procs. The SMG that lets you apply your damage consistently under pressure is the better weapon, even if its headline number is lower than a twitchier alternative.
Matching the SMG to your build
An SMG's value is relative to the character holding it. If your build stacks a particular element or rewards sustained fire and status effects, an SMG that feeds those bonuses becomes exceptional, while the same gun can be mediocre on a build oriented toward critical hits and single powerful shots. This is why borrowed loadouts disappoint: the SMG that is perfect for one character can be average on another with different skills.
Decide the role the SMG plays in your kit. Is it your primary damage dealer for most engagements, or a specialist tool for stripping shields and applying status before you switch to a heavier weapon? A primary SMG needs forgiving handling and magazine depth to carry long fights, while a specialist can afford a more extreme profile because you only use it for a specific job. Knowing the role tells you which stats to prioritize.
Factor in anointments and conditional bonuses. A conditional boost that lines up with how you play, such as bonus damage after an action skill or while a condition is active, can massively increase an SMG's practical value, while one that requires something you rarely do is wasted. Favor the conditional effects your playstyle triggers naturally, and an otherwise ordinary SMG can become a standout in your hands.
Consider carrying two SMGs with different elements rather than one do-everything gun. Because the class applies elements so quickly and so much of its value comes from matching element to enemy, a pair of SMGs covering different damage types lets you answer whatever a fight throws at you by simply swapping weapons. This is often more effective than hunting for a single perfect SMG, since no one element is ideal against every enemy. A two-element SMG setup is one of the most flexible and forgiving loadouts in the game for exactly this reason.
Think about how an SMG complements your heavier weapons, too. SMGs shine at applying status and stripping shields quickly, which makes them a natural partner for a slower, hard-hitting weapon that finishes the job once the target is softened. Used this way, an SMG does not need to be your top damage dealer to earn its slot; its speed and elemental uptime set up your bigger hits. Building your loadout as a set of cooperating tools, rather than a collection of standalone damage sources, gets more out of every weapon including a modest SMG.
Farming a great SMG
Specific legendary SMGs drop from specific sources, and those assignments can change with updates. Identify the current best source for the SMG you want, confirm it against an up-to-date drop guide, and farm it on the highest difficulty you can clear comfortably, since higher difficulty generally improves both drop rates and gear quality. Build a loadout tuned to kill that source fast so you can run it many times, because more attempts is how you beat a drop rate.
Because element and parts matter so much on SMGs, keep farming past your first copy until the roll suits your build. The same legendary can drop with different elements and parts, and only the version matching your damage plan is worth keeping. Hold onto promising rolls, compare them directly in a real fight, and do not settle for a copy whose element is wrong for the enemies you fight most.
When you compare two SMGs in that real fight, trust time-to-kill over the damage card. The card lists a single shot's damage, but what matters for a rapid-fire weapon is how much damage it puts on target across a full engagement, accounting for fire rate, magazine size, reload downtime, and how reliably you can hold it steady. An SMG with a lower card number but better sustained output and handling will often win the stopwatch test decisively. Measuring the real result against a consistent target is the only way to cut through the misleading headline numbers.
Keep an eye on how an SMG handles when a fight gets hectic, which is where this class earns or loses its reputation. A gun that is manageable on a calm range can spray wildly once enemies swarm and you are moving and dodging, so test your candidate under realistic pressure rather than in a controlled burst. The SMG you want is the one you can still keep on target when the screen is chaotic, because that is exactly the situation the class exists to handle. An SMG that only performs in ideal conditions is not the one to build around.
Do not neglect the humble stat rolls either. Bonuses to reload speed, magazine size, handling, or elemental effect chance quietly decide how an SMG feels across a long fight, and two copies of the same legendary can play very differently depending on these secondary values. When you have narrowed down the right SMG for your build, hold out for a copy whose supporting stats reinforce sustained fire, because those unglamorous numbers often separate a good SMG from a great one more than the headline damage does.
Getting the SMG you want the easy way
Farming the exact SMG with the right element and parts can take a lot of runs. If you would rather play than grind, the store offers an honest shortcut. The Borderlands 4 must-have weapons and gear service is a direct way to get strong equipment, and the full range is on the Borderlands 4 page. It is a time-saver, not a substitute for knowing how to use the weapon, so read up on your build too. Our guides on the best sniper rifle and on farming legendaries round out a complete loadout.
Frequently Asked Questions
What is the most important stat on an SMG?
Usually the element, because SMGs apply elemental effects fast. The right element for the enemies you face often out-damages a higher-base SMG with the wrong one, so match element to health type first.
Which manufacturer makes the best SMGs?
There is no universal best. Maliwan-style SMGs excel at elemental application and suit element builds, while other makers offer higher fire rates, better accuracy, or unusual projectiles. The best maker fits your build.
Why does an SMG feel worse for me than in a guide?
Because an SMG's value depends on the build holding it. If your skills reward critical hits or single powerful shots rather than sustained elemental fire, an SMG optimized for someone else will underperform.
Should an SMG be my main weapon?
It can be, but decide the role first. A primary SMG needs forgiving handling and magazine depth, while a specialist SMG for stripping shields and applying status can run a more extreme profile.
How do I farm a specific legendary SMG?
Find its current best source against an up-to-date guide, then farm it on the highest difficulty you can clear comfortably, since difficulty usually improves drop rates and gear quality. Keep going until the element and parts suit your build.
Does handling really matter on an SMG?
Yes. SMGs rely on sustained fire, so magazine size, reload speed, recoil, and accuracy decide whether you can keep damage on target. A controllable SMG often out-performs a higher-damage one you cannot steady.
