You’ve decided it’s time for a new everyday carry (EDC) pistol. You’ve done your homework, you know you want the legendary reliability of a Glock, and you’ve narrowed it down to two of their most popular slimline models: the Glock 48 and the Glock 43X. But now you’re stuck. On the surface, they look almost identical. They feel similar in the hand. So, what’s the real difference, and more importantly, which one is the right choice for you? This isn’t just about picking a gun; it’s about choosing the tool that could one day save your life. You need the full story, beyond the spec sheet.
That’s where we come in. This isn’t a quick, surface-level glance. We’re going to dive deep into the nuances of the Glock 48 vs 43x debate. We’ll explore every dimension, from how they feel on the hip during a long day to how they perform on the range when the pressure is on. We’ll talk about concealment, shootability, aftermarket support, and the revolutionary magazines that changed the game for both models. By the end of this guide, you won’t just know the differences—you’ll know exactly which of these two exceptional firearms belongs in your holster.
The Origin Story: Understanding Glock’s Slimline Family
To truly appreciate the Glock 48 vs 43x conversation, we have to rewind a bit. For years, the concealed carry market was dominated by two extremes: subcompact, snappy pistols that were easy to hide but hard to shoot well (like the original Glock 43), and larger, more shootable compact pistols that could be a chore to conceal (like the Glock 19). Shooters were forced to make a compromise. Do you prioritize comfort and concealment, or do you prioritize performance and capacity?
Glock answered this call with the introduction of the “Slimline” series. The genius of this line was its focus on reducing the profile where it matters most for concealment: the width. By slimming the slide and frame down to exactly 1.0 inch, Glock created pistols that disappeared under a t-shirt without sacrificing the crucial grip length that allows for a full, secure hold. The Glock 43X and the Glock 48 were unveiled together at the 2019 SHOT Show, and they immediately captured the attention of the carry world. They weren’t just new guns; they were a new category, offering a “best of both worlds” solution that countless shooters had been waiting for.
The shared DNA between these two models is immense. They both feature that coveted 1-inch slimline frame, identical ergonomics, and the same trigger, sights, and takedown procedure. This shared foundation is precisely why the choice between them is so intriguing. The differences are subtle but significant, focusing on one key aspect: the balance between concealment and a full-size sight radius. This foundational similarity sets the stage for a head-to-head comparison that is less about good versus bad and more about perfect for you versus perfect for someone else.
Breaking Down the Basics: A Side-by-Side Look
Before we get into the nitty-gritty of handling and performance, let’s lay out the cold, hard facts. A side-by-side specification table is the easiest way to see where these two twins diverge. It’s in these numbers that the core of the Glock 48 vs 43x debate takes shape.
| Feature | Glock 43X | Glock 48 |
|---|---|---|
| Overall Length | 6.5 inches | 7.28 inches |
| Barrel Length | 3.41 inches | 4.17 inches |
| Height | 5.04 inches | 5.04 inches |
| Width | 1.0 inch | 1.0 inch |
| Weight (Unloaded) | 18.7 oz | 20.74 oz |
| Sight Radius | 5.6 inches | 6.85 inches |
| Capacity (OEM) | 10+1 | 10+1 |
As you can instantly see, the height, width, and even weight are remarkably similar. The defining difference, the one that creates all the downstream effects, is length. The Glock 48 sports a longer slide and barrel, which in turn creates a longer overall pistol and a significantly longer sight radius. The Glock 43X, with its shorter slide, is the more compact of the two. This simple difference in length is the root of every argument, advantage, and trade-off we will discuss. It affects how the gun carries, how it points, how it shoots, and how it handles recoil.
It’s also crucial to note the one spec that is identical: height. This is why both pistols share the exact same magazine, a 10-round flush-fit mag that gives both guns a slimmer profile and higher capacity than the original Glock 43. This shared magazine platform was a game-changer and is a key reason both models are so popular. The aftermarket community, led by companies like Shield Arms, has further exploited this with 15-round metal magazines that fit both the 43X and 48, effectively blurring the capacity line between them and larger compacts. This means your decision is almost entirely freed from capacity concerns and can be based purely on handling and concealment preferences.
The Feel of the Grip: Ergonomics and Handling
Pick up a Glock 43X. Now, pick up a Glock 48. Close your eyes. Can you feel a difference? For most people, the answer is no, and that’s by design. Since the frame is identical in every dimension except for the dust cover at the front, the grip feel, texture, and overall ergonomics are exactly the same. Both pistols allow for a full three-finger grip for the vast majority of shooters, which is a massive advantage over smaller subcompacts where your pinky finger dangles off the bottom.
This excellent grip is the heart of the Slimline’s shootability. You get a firm, commanding hold on the pistol, which is the first and most important step in controlling recoil and placing accurate shots. The texturing on the frame is the standard Glock Gen5 pattern—aggressive enough to provide a solid purchase without being so rough that it chews up your skin or clothing when carrying inside the waistband. For those who want more, the aftermarket is flooded with options for grip tapes, stippling, and even silicone traction pads to customize the feel to your exact preference.
The controls are also identical. The magazine release is in the same spot, the slide stop lever is the same size and shape, and the trigger feel is indistinguishable out of the box. This means that from an ergonomic and muscle memory perspective, training on one directly translates to proficiency with the other. If you own both a Glock 48 and a 43x, you won’t have to relearn where the mag release is or how to manipulate the slide. This commonality is a huge benefit for shooters who value consistency across their firearms. The handling experience truly begins to diverge once you move past the grip and into how the pistol points and moves.
Concealment and Comfort: Which One Disappears Better?
This is the million-dollar question for anyone looking to carry a gun every day. All the performance in the world doesn’t matter if the pistol is so uncomfortable or prints so obviously that you leave it at home. In the realm of Glock 48 vs 43x, the concealment debate is fascinating because the answer isn’t as straightforward as “shorter gun is easier to hide.”
The Glock 43X, with its shorter slide and barrel, has a clear advantage in one specific area: the grip of the pistol won’t tip outward (a phenomenon known as “printing”) when you bend over or sit down. The shorter lever arm of the slide means there’s less mass below the beltline trying to pivot the grip into your shirt. For individuals with shorter torsos or those who spend a lot of time driving or sitting at a desk, the 43X can be noticeably more comfortable and less prone to revealing its presence during everyday movement.
However, the Glock 48 has its own concealment tricks. The longer slide and barrel actually help in certain carry positions, particularly appendix inside-the-waistband (AIWB), which is the most popular method for concealed carriers today. The longer slide helps to distribute the weight of the pistol more evenly along the belt line, preventing it from “keeling” or tilting outward. Furthermore, the longer barrel can actually aid in concealing the grip by providing a counterbalance that tucks the grip into the body more effectively. Many AIWB shooters find the Glock 48 to be more comfortable and stable, describing it as leaning against them rather than digging into them.
Ultimately, the best answer is to try both with a quality holster. The holster is just as important as the gun itself for concealment. A good holster for the 43X will almost always conceal better than a bad holster for the 48. Your body type, wardrobe, and preferred carry position will have the final say. For most people, the difference in concealment is marginal, but for those on the extremes of body type or those hyper-sensitive to printing, those marginal gains can make all the difference.
Shootability and Recoil Management: Taming the Snap
This is where the rubber meets the road, or more accurately, where the firing pin meets the primer. How a pistol feels in your hand when it’s static is one thing; how it behaves in your hand during the controlled explosion of a 9mm round is another. The Glock 48 vs 43x performance split is defined by physics, specifically the physics of mass, leverage, and pressure.
The Glock 43X, with its shorter, lighter slide, has less mass moving back and forth during the firing cycle. This can result in a perceived recoil impulse that is slightly sharper or “snappier” than its longer sibling. The muzzle may rise a bit more, and the pistol may require a slightly firmer grip to get back on target quickly for follow-up shots. This isn’t to say the 43X is unpleasant to shoot—far from it. It’s one of the softest-shooting pistols in its subcompact class. But when compared directly side-by-side with the Glock 48, the difference is noticeable to most shooters.
The Glock 48 uses its longer slide and barrel to its advantage here. The increased mass of the slide helps to soak up and dampen the recoil impulse, making it feel more like a push back into the hand than a sharp snap. The longer sight radius (the distance between the front and rear sights) also provides a tangible benefit for accuracy. It’s easier to spot small errors in your sight alignment, and it effectively makes the sighting system more precise. This often translates to better practical accuracy, especially at longer distances or for shooters who are still refining their fundamentals.
The legendary firearms instructor Massad Ayoob has often spoken about the advantages of a longer sight radius, noting its benefit for precision shot placement. While he may not have been commenting directly on the Glock 48 vs 43x, the principle holds true: all else being equal, a longer sight radius makes accurate shooting easier.
For new shooters or those with less hand strength, the Glock 48 is often the easier pistol to learn on and shoot well. The slightly softer recoil and easier sight picture can build confidence faster. However, the 43X is by no means unmanageable, and with practice, a skilled shooter can run both pistols with nearly identical speed and precision.
The Holster Ecosystem: Finding a Home for Your Pistol
You can have the perfect pistol, but without a good holster, it’s just a paperweight. Fortunately, both the Glock 48 and 43X are incredibly popular, which means the aftermarket holster support for them is absolutely massive. You will have no trouble finding dozens of high-quality options from every major manufacturer for either model.
There is, however, a crucial detail to be aware of. While the frames are the same width, the slide length is different. This means that most holsters are model-specific. A holster designed for a Glock 48 will have an open bottom to accommodate the longer slide, and a Glock 43X will rattle around inside it. A holster designed for a Glock 43X will have a closed bottom, and a Glock 48 simply will not fit into it. This is the most important practical consideration when choosing between the two.
Many holster makers, recognizing that shooters might own both or be deciding between them, now offer modular systems. For example, a company might sell an AIWB holster “shell” that can be fitted with different “body” pieces to accommodate either the 48 or the 43X. This allows for some flexibility, but you generally can’t mix and match. The good news is that the popularity of both models ensures that you have a wealth of choices in every style—leather, Kydex, hybrid—and for every carry position imaginable, from appendix to strong-side hip to ankle carry.
When shopping for a holster, prioritize quality. Look for durable materials, solid retention adjustment, a solid belt clip or loop, and most importantly for appendix carry, a design that includes features like a “wing” or “claw” to tuck the grip into your body and a “wedge” to comfort the muzzle. A $70 holster that you wear every day is a far better value than a $30 holster that sits in a drawer because it’s uncomfortable.
6.5 Grendel vs 6.5 Creedmoor: The Ultimate Showdown
The Magazine Revolution: OEM vs. Aftermarket
When these pistols were first released, they both shared one potential drawback: a 10-round capacity. In a world where micro-compacts like the Sig Sauer P365 were offering 10, 12, and even 15 rounds in a similarly small package, Glock’s design seemed conservative. Then, the aftermarket came to the rescue in a huge way, and it changed the entire Glock 48 vs 43x calculation.
Companies like Shield Arms developed aftermarket magazines that completely altered the capacity game. Their S15 magazine is a marvel of engineering: a metal-bodied magazine that holds 15 rounds of 9mm ammunition while maintaining the same flush-fit profile as the OEM 10-round plastic magazine. This instantly brings both the 43X and the 48 up to a 15+1 capacity, putting them squarely in the same league as much larger guns like the Glock 19.
This development is a huge point in favor of both models, but it does come with a caveat. Because the S15 magazines are metal, they require a corresponding metal magazine release to be installed. The factory polymer release will be worn down over time by the harder metal magazine. For many, this simple $20 swap is a no-brainer for a 50% increase in capacity. For others, particularly those who prioritize absolute reliability above all else, sticking with the factory Glock magazines is the preferred path.
This aftermarket option effectively neutralizes capacity as a differentiator between the two pistols. Whether you choose the Glock 48 or the 43x, you have the exact same potential for 15+1 rounds on tap. This allows you to make your decision purely based on the shootability and concealment factors we’ve already discussed, without feeling like you’re sacrificing ammunition. It’s a testament to the vibrant aftermarket that supports the Glock platform.
Customization and the Aftermarket World
Glock pistols are famously like the LEGOs of the firearms world: incredibly modular and easy to customize. Both the 48 and 43X benefit from this vast ecosystem, allowing you to tailor your pistol to your exact needs and preferences. From performance upgrades to aesthetic tweaks, the possibilities are nearly endless.
The shared frame between the two models means that any accessory that attaches to the frame is interchangeable. This includes things like magazine releases, slide stops, and grip plugs. More importantly, it includes weapon-mounted lights. The rail on the dust cover of both pistols is identical, meaning all the same lights will fit. Popular models like the Streamlight TLR-7 Sub and various offerings from SureFire will attach perfectly to either the Glock 48 or the 43x, giving you excellent low-light capability.
The slides, being different lengths, are naturally not interchangeable. However, each has a huge market of its own. You can easily find aftermarket slides from companies like Brownells, Zaffiri Precision, and others, offering windows, optic cuts, and different serrations. Speaking of optics, both models are now widely available in MOS (Modular Optic System) configurations from the factory. The Glock 43X MOS and Glock 48 MOS come pre-milled with a plate system to accommodate popular micro red dots like the Shield RMSc, Holosun EPS Carry, and Trijicon RMRcc. Adding a red dot to either of these pistols is a massive force multiplier, dramatically increasing speed and target acquisition.
Whether you want to keep it stock or build a full-blown custom carry piece, both platforms offer a blank canvas. You can change the trigger, add night sights, stipple the frame, or cerakote the slide. This ability to personalize your tool is a key part of the Glock ownership experience and ensures your pistol can evolve with your skills and needs.
Making Your Choice: Who is Each Pistol For?
After all this analysis, it’s decision time. So, which one should you walk out of the store with? Let’s break down the ideal candidate for each model in the Glock 48 vs 43x pairing.
The Glock 43X is the ultimate deep concealment pistol. It is the ideal choice for:
- The individual with a smaller frame or shorter torso who needs the absolute shortest slide possible to maximize comfort when bending and sitting.
- The shooter who values the slight advantage in concealment that the shorter slide provides and is confident in their ability to manage the minimally snappier recoil.
- Anyone whose primary concern is the pistol disappearing completely, whether due to their wardrobe, body type, or profession.
The Glock 48 is the shootability champion. It is the perfect fit for:
- The shooter who prioritizes a smooth, manageable recoil impulse and a longer sight picture for increased accuracy.
- Individuals with medium to larger frames who find the longer slide provides better balance and comfort, especially in appendix carry.
- New shooters who will benefit from the softer-shooting, more forgiving platform as they build their foundational skills.
- Anyone looking for a “do-it-all” pistol that splits the difference between a full-size range gun and a concealed carry tool, offering remarkable performance in a concealable package.
Many experienced shooters and instructors, like the team at Sage Dynamics, have praised the Glock 48 MOS as one of the best overall carry packages on the market, citing its excellent balance of size, capacity, and shootability, especially when paired with a red dot sight.
For many, the best solution might even be to own both. The frames are identical, so your holsters, lights, and muscle memory largely translate. You could have a 43X for ultra-deep concealment in the summer and a 48 for general carry the rest of the year. The beauty of the Slimline family is that you’re not choosing between two completely different systems; you’re choosing between two nuanced variations of an exceptional platform.
Conclusion
The Glock 48 vs 43x debate doesn’t have a single winner. It has a winner for you. These are two of the most refined and effective concealed carry pistols ever made, both offering Glock’s legendary reliability in a sleek, high-capacity package. The Glock 43X leans ever so slightly towards the concealment side of the spectrum, offering a marginally smaller and lighter package.

Frequently Asked Questions
Is the Glock 48 more accurate than the Glock 43X?
In mechanical terms, both pistols are likely equally accurate, as they share the same rifling and manufacturing quality. However, the longer sight radius of the Glock 48 makes it easier for most shooters to achieve accuracy. It provides a clearer, more defined sight picture, which helps in aligning the sights precisely. For a beginner or a shooter looking for every possible advantage, the Glock 48 can often lead to better practical accuracy on the target.
Can I use Glock 43X magazines in a Glock 48?
Yes, absolutely. This is one of the biggest advantages of this platform. The magazines are completely interchangeable because the grip frames and magazine wells are identical on both pistols. The same OEM 10-round magazines and aftermarket options like the Shield Arms S15 magazines will function perfectly in either the Glock 48 or the 43x.
Which one has more recoil, the Glock 48 or 43x?
The Glock 43X generally has a slightly sharper or “snappier” felt recoil due to its shorter, lighter slide. The Glock 48’s additional slide mass helps to dampen the recoil impulse, making it feel a bit softer and more like a push than a snap. The difference is noticeable when shooting them back-to-back but is not dramatic. Most shooters find both to be very manageable, especially compared to other pistols in the micro-compact category.
Is the Glock 48 harder to conceal than the 43X?
It can be, but it’s highly dependent on your body type and how you carry. The longer slide and barrel of the Glock 48 can sometimes print more when bending over for some body types. However, for appendix carry, many find the longer slide actually helps by balancing the gun and tucking the grip in more effectively. For most people, the difference in concealment is minimal, but for those seeking the absolute smallest profile, the 43X has a slight edge.
Should I get the MOS version of either pistol?
If you have any intention of ever using a red dot sight, we highly recommend getting the MOS version. The ability to mount a micro red dot like a Holosun EPS Carry is a significant advantage for target acquisition and speed, especially in a defensive scenario. While you can get a non-MOS slide milled by a gunsmith later, buying the MOS model from the factory is often more cost-effective and gives you the flexibility to use different optic footprints with adapter plates.
