Ask a Rainbow Six Siege player how much time they’ve spent practicing their secondary weapon and watch the silence. The average ranked player has thousands of hours on their primary rifle and essentially zero on the pistol sitting in the second slot. The secondary is the forgotten corner of the loadout screen — picked by default, never trained, and reached for only in desperation.
That neglect costs rounds. The secondary wins fights the primary can’t: the mid-gunfight reload, the range your primary doesn’t cover, the single bullet that decides a clutch. And on certain operators, the secondary isn’t a backup at all — machine pistols like the SMG-11 and Bearing 9 are genuine second primaries that reshape entire loadouts.
This guide is the secondary-as-system masterclass: the three situations where your secondary decides the round, the switch discipline that separates practiced players from panicked ones, and a practice routine that builds it.
Why Secondaries Matter: The 3 Situations
The secondary matters rarely — but when it matters, nothing else substitutes. Learn to recognize the three situations, because each demands a different habit.
Situation 1: the dry primary. You’re mid-gunfight, your magazine runs out, and the enemy is still standing. The instinct is to reload. The correct play is to switch. A weapon switch takes a fraction of a second; a reload takes several times longer. That gap is the difference between winning the trade and dying behind cover with a half-loaded rifle. This is the single most common secondary situation in Siege, and it has a simple rule: switch, don’t reload, when the enemy is close and active. The “switch don’t reload” rule is worth memorizing as a mantra, because in the moment your hands will do whatever you’ve trained them to do.
Situation 2: range coverage. Your primary has a range it doesn’t handle — the shotgun outside its lethal distance, the DMR in a point-blank scramble, the rifle when you’re out of ammo entirely. The secondary fills the gap. This is the pairing logic our loadout guide covers in full: your secondary should cover what your primary can’t. The classic example is the shotgun operator’s SMG-11 — shotgun for the room, machine pistol for the hallway — but the principle applies everywhere. A secondary chosen to cover your primary’s weakness turns a one-dimensional loadout into a complete one.
Situation 3: the “one more bullet” clutch. Late round, low health, one enemy left, and your primary is dry, reloading, or the wrong tool for the angle. The secondary is the gun that finishes the round. Clutches are won on margins — a pistol round that takes two seconds of practice-rep confidence versus a panicked spray that misses everything. Players who practice their secondary win measurably more clutches, not because the pistol is strong, but because they aren’t afraid of it.
The thread connecting all three: the secondary is a skill you build before you need it. Nobody learns to switch weapons mid-gunfight for the first time and succeeds.
Pistol Deep-Dive: The Backup That Wins Fights
Standard pistols — the P9, the 5.7 USG, the P229, the Mk1 9mm, the D-50 and the rest — share a job description: reliable, always available, and good enough to win a fight you shouldn’t have started. They’re not exciting. That’s the point. A pistol is the tool you reach for when the plan broke, and its virtue is that it’s always there.
What pistols do well. They’re fast to draw, accurate on the first shot, and perfectly adequate inside close range. The pistol’s real strength is availability: it’s the gun that’s loaded when your primary isn’t.
When pistols win. The dry-primary switch at close range is the pistol’s signature win. So is the “wrong gun” moment: you rounded a corner with your breaching tool out, or you’re caught mid-gadget. The pistol is the universal answer to being caught wrong-footed.
The practice nobody does. Most players’ pistol skill is whatever carried over from rifle practice, minus everything that makes pistols different. Dedicated pistol practice is rare enough that doing even a little of it puts you ahead of most of the lobby. In your warmup, spend five minutes on pistol-only target work — draw, fire two to three controlled shots, re-holster. Build the draw-and-fire motion as its own muscle memory, separate from your rifle habits.
One caveat worth stating: pistol balance shifts with patches, and some operators’ pistols are meaningfully better than others’. Verify your operator’s secondary options in-game each season. The practice principles here outlast any patch; the specific numbers don’t.
Machine Pistols Deep-Dive: The Second Primary
Machine pistols — the SMG-11, the Bearing 9, the SMG-12 and their cousins — are a different species from standard pistols. They’re automatic, they hit hard, and on the operators who carry them, they function as a genuine second primary rather than a backup.
The SMG-11. The most famous secondary in Siege, and the reason shotgun loadouts work. A blistering fire rate with genuine mid-range effectiveness. For Smoke, Mute, and the other shotgun operators, the SMG-11 is what makes the shotgun viable: shotgun for the room, SMG-11 for everything else. Our shotgun guide covers this pairing in depth — the SMG-11 doesn’t back up the shotgun; it completes it.
The Bearing 9. Hibana’s signature machine pistol and one of the most beloved secondaries in the game. Where the SMG-11 is a range-extender, the Bearing 9 is a close-quarters shredder — an automatic secondary that turns Hibana into a two-gun threat. Operators with machine pistols effectively have no “weak” weapon slot, which changes how you should think about their loadouts: the primary choice becomes about the job (destruction, range, utility) while the machine pistol handles the fighting.
Why they change entire loadouts. A normal pistol is a compromise you accept. A machine pistol is a capability you build around. When your secondary can win mid-range fights, your primary is free to specialize — take the shotgun, take the DMR, take the niche pick — because the secondary covers the general case. This is the loadout-system thinking from our loadout guide: the pair is the weapon, not either gun alone.
Who gets them, and what it means. Machine pistols are concentrated on a handful of operators — mostly defenders with shotguns or utility-heavy kits. If your main has one, your practice priorities shift: the machine pistol deserves real training time, not pistol-afterthought time. Treat it as a primary that lives in the secondary slot.
The Switch Discipline: Timing Is Everything
Knowing the secondary exists isn’t the skill. The skill is the switch — and switches are won or lost on timing and habit.
The “switch don’t reload” rule, precisely. When your primary runs dry and the enemy is within close-to-mid range and actively engaging, switch. The switch is faster by a wide margin, and you need a gun now, not a full magazine in two seconds. The exception: the enemy is far, behind cover, or you’ve broken contact. Then reload behind safety. The rule isn’t “always switch” — it’s “switch when time matters more than ammunition.”
Switch timing in the range-coverage case. This is the harder switch, because it’s proactive rather than reactive. You’re holding a shotgun and rotating through a hallway: the secondary should already be out. Build weapon awareness by position — primary for the job you’re doing, secondary for the space you’re moving through. Shotgun out when holding the close angle; SMG-11 out when crossing open ground.
Building the habit. Add a switch drill to your warmup: fire your primary dry at a target, switch, fire three controlled secondary shots, switch back, reload. Repeat ten times. It takes three minutes and it programs the motion your hands will default to under pressure. The goal is to make the switch as automatic as the reload currently is.
The re-holster trap. After the fight, switch back and reload the primary. Players who win the secondary fight and then push the next angle still holding the pistol are making the mirror-image mistake.
Secondary + Primary Pairing Logic: The System View
The deepest secondary skill isn’t mechanical — it’s loadout thinking. The secondary and primary are one system, and the pairing should be deliberate.
Cover the weakness. Every primary has a gap: shotguns lack range, DMRs struggle up close, rifles run dry. The secondary’s first job is to cover that gap. When you’re choosing between a standard pistol and a machine pistol, ask: what does my primary not do? Pick the secondary that answers that question. This is the pairing logic from our loadout guide applied at the smallest scale.
The two-gun mindset. Stop thinking of your loadout as a primary with a backup. Think of it as two guns with different jobs that you alternate between as the situation demands. The shotgun/SMG-11 operator isn’t a shotgun player — they’re a close-range system player. This reframing changes practice: you stop training “my gun” and start training “my guns.”
When the secondary becomes the primary. On machine-pistol operators, and when your primary is dry with no safe reload, the secondary takes over as the main weapon. Recognizing that shift — and committing to it — is advanced play.
Secondary Practice Routine: How to Actually Train It
Nobody practices the secondary because nobody knows how. Here’s a ten-minute routine that covers everything.
Minutes 1–3: the switch drill. Fire your primary dry at a wall target, switch, fire three controlled secondary shots, switch back, reload. Ten repetitions. This programs the dry-primary response — the highest-value secondary habit in the game.
Minutes 4–6: secondary-only target work. Pistol or machine pistol only: draw, two to three shot groups, re-holster, repeat. Focus on the first shot’s accuracy — the secondary’s job is usually decided in the first few bullets.
Minutes 7–8: range transitions. Start close with the primary out, move to mid-range switching to the secondary as you move, engage, move back switching to the primary. This trains the proactive switch.
Minutes 9–10: pressure reps. Combine everything at speed: dry the primary, switch, engage, switch back, reload, move, repeat. Push the pace until the motions blur. The secondary is a stress weapon, so train it under stress.
Do this three times a week for a month and your secondary will go from liability to asset. Ten minutes, three times a week, against a skill nobody else is training — the return on investment is enormous precisely because the baseline is zero.
The 3 Secondary Mistakes
1. Never practicing it. The meta-mistake that causes all the others. The secondary is the only weapon slot most players never deliberately train, which means every secondary situation is handled with borrowed skill and panic. Ten minutes, three times a week — that’s the entire fix.
2. Wrong switch timing. Two failure modes: the reload-when-you-should-switch (dying behind cover with a half-loaded primary while the enemy pushes), and the switch-when-you-should-reload (winning the close fight with the pistol, then pushing the next angle still holding it). Both come from the same root: no practiced decision rule. Memorize the rule — switch when time matters more than ammunition — and drill it until it’s reflex.
3. Ignoring the machine pistol. Players who have an SMG-11 or Bearing 9 and treat it like a normal pistol are leaving the strongest secondary in the game on the table. Machine pistols deserve primary-level practice and primary-level respect in your loadout thinking. If your operator has one, it’s not a backup — it’s half your kit. And if you’re choosing operators partly by loadout, the machine pistol is a legitimate tiebreaker: it makes everything around it better.
Frequently Asked Questions
Should I ever use my pistol over my primary on purpose?
Rarely, but yes: the dry-primary moment where switching beats reloading, and quiet repositions where the pistol’s softer signature matters. What you should never do is choose the pistol over a loaded primary in a fair fight.
Which operators have machine pistols?
A small set, concentrated among defenders — most famously Smoke with the SMG-11 and Hibana with the Bearing 9. The roster shifts with balance patches, so check your operators’ loadout screens in-game. If your main has one, treat it as a core part of the kit, not a bonus.
Is the SMG-11 really that good?
Yes — it’s widely considered the best secondary in Siege, and the reason is the pairing logic this guide is built on: it gives shotgun operators a genuine mid-range gun, which makes the shotgun pick viable. Verify its current tuning in-game, but the role it plays has been consistent for years.
How do I stop reloading when I should switch?
Drill it. The switch drill in the practice routine exists specifically for this: dry the primary, switch, fire, repeat. Ten reps, three minutes, three times a week. Your hands default to whatever they’ve done most recently — so make the switch the thing they’ve done most recently.
Should beginners practice the secondary?
Yes, but proportionally. Beginners should spend most training time on their primary — that’s where most fights are won. But even five minutes of switch-drill practice a week builds the habit early, before bad defaults set in.
Pistol or machine pistol — which should I pick when I have the choice?
The machine pistol, in almost every case. Higher fire rate, better damage output, more forgiving. If the choice exists, take the machine pistol and practice it.
The Bottom Line
The secondary is the most undertrained slot in Siege, which makes it the highest-leverage one to fix. The system is simple: know the three situations (dry primary, range coverage, the clutch bullet), respect the machine-pistol tier (the SMG-11 and Bearing 9 are second primaries, not backups), live the switch discipline (switch when time matters more than ammunition, and drill it until it’s reflex), and think in pairs (the secondary covers what the primary can’t — choose it deliberately, as our loadout guide teaches).
Ten minutes, three times a week. That’s the price of turning the forgotten slot into a round-winner. Your primary wins most of your fights. Your secondary wins the ones that matter most. Train it like it matters, because it does.
