Best Glock 43X Holster for Concealed Carry: Comfort, Concealment, and Appendix Carry Done Right

The Glock 43X lives in that rare zone where a pistol is small enough to disappear but still feels like a real handgun when you grip it. Not a novelty. Not a compromise you tolerate. A tool you can actually run.

The best Glock 43X holster for concealed carry is a purpose-built IWB Boltaron holster with adjustable retention and ride height that stays stable in appendix carry and reduces printing.
For most carriers, CYA Supply Co’s IWB holsters are the best fit because they’re designed for real daily wear: consistent retention, stable belt attachment, and concealment-focused geometry.

Glock built the 43X around the Slimline idea—thin profile, carry-focused, and a 10-round magazine capacity that fits the concealed carry mission without turning the gun into a brick. You can see Glock’s own positioning of the model right on their product pages for the G43X and the optics-ready G43X MOS.

And that’s why this keyword matters: people searching “Best Glock 43X holster for concealed carry” aren’t window shopping. They’re trying to solve a daily problem. They’ve got a 43X (or they’re about to), and they want the setup that won’t make them quit carrying by week two.

Because here’s the gritty truth: most carriers don’t stop because the gun is “too big.” They stop because the holster turns the gun into a constant irritation—printing, shifting, jabbing, sliding, or rubbing them raw. The 43X is supposed to be easy. If it isn’t, the holster is usually the culprit.

This guide breaks down what actually matters—comfort, concealment, appendix carry—and then points you into the right CYA Supply Co IWB holster lane so your 43X rides like it belongs there.

Why the Glock 43X Is So Common on Real Carry Belts

The 43X hit a sweet spot: slim slide, longer grip than a tiny micro, and enough capacity to feel like you’re not under-equipped. Glock specifically calls out the slim profile and 10-round capacity as part of the concealed carry intent. The NRA’s Shooting Illustrated review also highlights the 43X’s 10-round capacity and concealed-carry design language.

But popularity cuts both ways. When a pistol gets carried this much, people notice the friction points fast—especially with appendix carry. The 43X has a grip length that can print if the holster lets it tip outward. And because the gun is thin, it can feel deceptively “shifty” in a cheap holster that doesn’t anchor well.

So “best holster” isn’t about hype. It’s about controlling those friction points.

What “Best” Actually Means for a Glock 43X Holster

If you want comfort and concealment that holds up through real life, your holster needs three things locked down:

1) Stability (so it doesn’t migrate)

A holster that shifts on your belt turns your draw into a guessing game. In appendix carry, it can also turn into constant adjustment—tug, twist, re-seat, repeat. The best holster is the one that stays put when you move, sit, drive, and bend.

2) Concealment control (so the grip doesn’t print)

With the 43X, printing usually isn’t the slide. It’s the grip. A good IWB holster keeps the grip pulled in so your shirt drapes naturally instead of catching the butt of the gun every time you lean.

3) Consistent retention (so the draw is repeatable)

Retention should feel secure and predictable—not “death grip tight” and not loose. You want a draw that stays the same on day 1 and day 300.

That’s the baseline. Everything else is preference—but those three are non-negotiable.

Why IWB Is the Move for the Glock 43X

If the goal is concealed carry, IWB (inside the waistband) is the workhorse for most people. It keeps the gun tight to the body and reduces the “outside the belt” silhouette that OWB setups can create.

OWB can conceal under heavy layers, sure. But if you’re carrying in normal clothes—T-shirt, hoodie, flannel—an IWB holster is usually what gets you through the day without printing.

And when the focus angle is comfort + concealment + appendix carry, IWB is the answer nine times out of ten.

Appendix Carry with the Glock 43X: Where Holsters Either Shine or Fail

Appendix carry (AIWB) is popular because it’s fast, accessible in tight spaces, and often conceals well… when the holster is right.

When it’s wrong, it’s miserable.

Here’s what makes appendix carry with a 43X either smooth or brutal:

• Ride height: Too high and the grip prints. Too low and you can’t get a clean firing grip.
  
  

• Angle/cant: A few degrees can change everything—comfort, concealment, and draw efficiency.
  
  

• Holster stability: If it rolls outward, the 43X grip becomes a billboard.
  
  

Appendix carry is where “best holster” becomes real. Because AIWB doesn’t tolerate sloppy geometry or weak belt attachment.

Boltaron vs Leather for the 43X: Why Boltaron Wins for Most Carriers

Leather has tradition. But daily concealed carry demands consistency.

Boltaron gives you:

• repeatable retention
  
  

• rigid trigger-guard coverage
  
  

• a holster mouth that stays open for safe reholstering
  
  

• durability against sweat and daily abuse
  
  

For a pistol like the 43X—meant to be carried a lot—Boltaron is usually the best material choice because it holds its shape and keeps performance consistent through heat, humidity, and real wear.

The Best Glock 43X Holsters in the CYA Supply Co Lineup

CYA Supply Co’s lineup is built around what concealed carriers actually need: stable IWB carry, consistent retention, and comfort that makes you keep the gun on your body.

Here’s how to choose inside the CYA family—without overcomplicating it.

CYA Base IWB for Glock 43X: the daily-driver workhorse

If you want a straightforward IWB holster that’s dependable, comfortable, and easy to live with, the Base IWB is the move. It’s the holster you can run all day without feeling like you’re wearing “a rig.” It keeps things clean and functional—exactly what most 43X carriers want.

This is the choice for the carrier who wants:

• solid concealment fundamentals
  
  

• consistent retention
  
  

• an IWB holster that doesn’t demand constant adjustment
  
  

CYA Ridge IWB for Glock 43X: more refined, more dialed-in

If you’re appendix carrying the 43X and you’re serious about comfort and concealment—especially if you’re trying to reduce printing and improve long-wear comfort—the Ridge IWB is where you go.

This is the lane for the carrier who’s optimizing:

• appendix comfort during sitting/driving
  
  

• concealment stability (less grip tip-out)
  
  

• a more “tuned” feel overall
  
  

If you’ve ever made it to lunchtime and thought, “I can’t wait to take this thing off,” that’s a signal. You don’t need a different gun. You need a better holster setup.

Don’t Forget the 43X MOS Factor: Optics and Real-World Setup

A lot of 43X owners end up with the MOS model because optics are normal now, not “tactical extra.” Glock’s own description of the G43X MOS highlights its Slimline design and MOS configuration.

If you run (or plan to run) a red dot:

• make sure your holster is optic-ready
  
  

• make sure the cut clears the sight without rubbing or dragging on the draw
  
  

Buying a holster that can’t support your future setup is how people spend money twice.

Comfort and Concealment Tips That Matter More Than People Admit

If you want the best Glock 43X concealed carry experience, treat it like a system:

Use a real gun belt. A flimsy belt makes even a great holster feel bad. The belt is what prevents roll-out and keeps the grip from tipping and printing.

Tune your retention. Too tight and you won’t train. Too loose and you won’t trust it. Find the “locked in but smooth” zone.

Dress like a carrier, not like you’re hiding a secret. Slightly heavier fabric, a normal drape, and a consistent wardrobe approach beats constant fidgeting.

And if you’re carrying appendix: adjust ride height and angle until you can sit, stand, and move without fighting the gun.

Final Take: The Best Glock 43X Holster Is the One You’ll Still Wear Tomorrow

The Glock 43X became a carry staple because it’s thin, capable, and easy to live with. But the holster decides whether that promise holds up.

If you want a clean, reliable IWB setup that’s built for daily carry, start with the CYA Supply Co Base IWB. If you’re focused on appendix carry comfort and concealment refinement, step into the CYA Supply Co Ridge IWB.

Either way, the mission is the same: a holster that makes carrying the 43X feel normal—not like a chore you negotiate with.
