I get so many requests for a showdown of the Glock 48 vs 19 that I think high-time we get to it.

The Glock Model 19 stands as Glock's most popular firearm, coveted for its concealable nature without compromising on the feel of a full-size gun. Personally, I've been a devoted fan of the Glock 19 for over 30 years, relying on it as one of my most trusted companions. If I were forced to choose just one handgun, it could easily be the Glock 19.

Many of my friends share this sentiment - though not necessarily because it's the best gun, but rather because of the profound bond we've developed with it over time.

However, the introduction of the G48 provided an intriguing twist. These two pistols share an almost identical profile yet offer distinct differences in ammunition capacity. The G48, like the similar G43X, carries 10 rounds, while the G19 holds up to 15 rounds. The Glock 48 offers a sleeker design compared to the Glock 19, with a slightly slimmer profile of almost a quarter of an inch.

Now, let's delve into the advantages and disadvantages of both these pistols, starting with a Glock 48 vs 19 side-by-side comparison of their main features.




Let's kick this off with a detailed breakdown of the main specs the Glock 48 and Glock 19, shall we?

This comparison shows that while both guns share the same system and similar dimensions, Glock 19 has a higher magazine capacity and is slightly heavier than the Glock 48. The overall length and width of the Glock 19 are also slightly larger. The trigger pull of Glock 19 is stronger compared to Glock 48.




The ergonomics of these firearms are remarkably similar, but the frame of the Glock 48 is noticeably slimmer compared to the Glock 19. Overall, you won't find a substantial difference between the two apart from the width. Personally, I find it easier to grip and shoot the Glock 19 because the frame feels more comfortable in my hand due to its thickness.

I’d say the Glock 48 is going to be a superior choice for individuals with smaller hands. Unlike the Glock 19 in the Gen4 and Gen5 variants, it lacks removable backstraps and modularity to adjust the grip size for larger hands.


Grip Generation Gap


Some of you have likely noticed how the texture of the Glock may vary depending on the generation. Although the manufacturer classifies the Glock 48 as a Glock Gen 5 texture, I think it actually shares more Gen 4 features. In my opinion, the texture of the Glock 19 Gen 5 is slightly more aggressive compared to the Gen 4, making it the ideal choice for a production handgun. It strikes the perfect balance, providing a secure grip without causing any discomfort when carrying it close to the body.

The Gen 4 style texture is certainly functional but not exceptional. Ideally, I would have preferred Glock to adopt the “truer” Gen 5 texture for this particular handgun, considering it was released after the introduction of the Glock Gen 5. Nevertheless, it still performs adequately.

For those who prioritize texture, the difference between the G48 and G19 is a crucial factor to consider.




The slides have remarkable similarities except for their width. Notice a pattern emerging here? Due to its narrower width, manipulating the Glock 48 slide might be slightly more challenging as compared to the 19. You don't get the same level of grip as you do with the latter. However, it's worth noting that both slides are fairly comparable.




With the G48, you get a 10-round magazine, while the G19 offers 15 rounds, giving you an extra five rounds - but with the introduction of a Shield Arms' 15-round mag to your equipment means a 15+1 capacity for your Glock 48 or 43X; effectively matching the G19's 15-round magazine. However, the G19 boasts a thicker slide and grip, that some say evens out the playing field.

Moreover, you have the option with a G19 to use a G17 magazine that holds 17+1, or the G19X with 19-round magazines. Additionally, Glock offers a 33-round magazine fun stick, taking things to a whole new level.

This gives you more choices with the G19, whereas options are more limited for the G48 and 43X, although the S15 magazine is arguably a significant game-changer for the latter.




The Glock 48 differs from the MOS variant in a notable way - it lacks an accessory rail. The Glock 48 MOS, on the other hand, offers a built-in optics modularity feature. (MOS stands for Modular Optic System, enabling the easy integration of various micro red dot sights on its slide cuts.)

While the G48 boasts a slim slide that cannot accommodate most red dot sights, the G48 MOS is specifically designed with slide cuts to accommodate specific micro-optics.

Conversely, the Glock 19 has a standard accessory rail, allowing the attachment of lights and lasers, making it well-suited for home defense purposes. Many concealed carry firearm owners appreciate the addition of a light on their home defense weapon.

Moreover, the MOS version of the Glock 19 comes with RMR cuts, enabling the use of a red dot or electronic sight. Unfortunately, the standard Glock 48 lacks this option due to its slender slide design. Nonetheless, the Glock 48 excels in its compactness while providing limited compatibility with red dot sights.

Those seeking optic versatility may find the Glock 48 MOS to be the ideal choice, thanks to its tailored optics modularity with the micro red dot Shield RMSc.




When it comes to comparing any handgun, the real test comes on the range - and with the G48 and the G19 you can truly notice the distinctions between these two handguns.

Firstly, both pistols feel substantial and offer a secure grip. However, the G48 has a slightly thinner and more ergonomic grip, which was a surprisingly welcome change for many I talked to, as many feel the Glock has been known to feel somewhat bulky. The G48 allows for a solid and high hand placement on the firearm, even with its thinner profile and reduced back strap.

Also, surprisingly, the G48 exhibited a bit more muzzle rise compared to the G19, which I personally prefer shooting. Despite having expected slightly more felt recoil from the heavier slide mass of the G19, the opposite turned out to be true for me. Without a side-by-side comparison available, I’d say the difference would be negligible. Having fired numerous rounds through both the G48 and the G19, I can confidently say that they are both exceptional handguns.




The G48 has the same frame size as the G43X, allowing for that great interchangeability you find with many Glock products. For example, you can replace the G48 frame with the G43X slide, resulting in a shorter slide system. Additionally, if you already own a regular G43, the slide will also fit on this frame.

This flexibility is a significant advantage of owning a G43 and the G48. You have the option to switch between a long slide and a shorter slide, unlike the G19, where you are limited to the G19 slide.However, aftermarket options do exist for getting long slides for the G19 and other parts/upgrades for your G48 non-MOS. If you're interested in adding a laser or a light, there are suitable options available, such as Streamlight and Surefire, which make attachments that can be easily clipped to the front trigger guard.




Undoubtedly, when it comes to concealed carry, the Glock 48 takes the lead. With its slighter, shorter, and lighter design, it's an ideal choice for individuals with a smaller build. However, let's not overlook the longstanding reputation of the Glock 19 as the gold standard in concealed carry – it continues to excel in fulfilling that role.

The G48 is the epitome of uncompromising balance between handling ease and compactness. Shrunken down to the smallest dimensions possible, the G48 is essentially a Glock 19 in a more streamlined form.

With its optimal design for inside-the-waistband (IWB) carry – when paired with suitable Glock 48 holsters – it introduces a new level of comfort and concealed carrying. On the other hand, the Glock 19, in my view, excels in outside-the-waistband (OWB) carry, but with the right Glock 19 IWB holster, it can also be an exceptional inside waistband choice.

If you desire a concealed carry firearm equipped with a weapon light and red dot optic, the Glock 19 is an outstanding option. It provides a perfect balance between compactness, functionality, and enhanced sighting capabilities.

If you prefer a slightly larger firearm with additional features, the Glock 19 is a great option to consider. It is ideal for those seeking a reliable, duty-worthy handgun.

On the other hand, if your goal is to carry a compact firearm without compromising performance, the Glock 48 is the perfect choice. This thin and lightweight gun has redefined concealed carry, presenting new possibilities in the market.

Both firearms offer unique advantages depending on your priorities, ensuring that you have the right tool for your needs.




In conclusion, to anyone comparing the Glock 48 and Glock 19, it’s pretty evident that both firearms are very similar but have their own minor strengths and advantages. Whether you lean towards the Glock 19, with its higher magazine capacity, versatility, and compatibility with accessories, or the Glock 48 with its sleek, compact design ideal for concealed carry, your choice ultimately depends on your specific needs and preferences.

However, one common factor that should not be overlooked, regardless of your choice, is the importance of a dedicated holster. No matter if you opt for the Glock 19 or the Glock 48, ensuring that you pair it with a high-quality, dedicated Glock 19 holster or Glock 48 holster is essential. A well-designed holster not only keeps your firearm secure but also ensures quick and reliable access when you need it most.

So, no matter which Glock model you choose, make sure you invest in the right holster to complement your firearm and enhance your overall preparedness and safety. Your choice of holster can be just as critical as your choice of firearm. Stay safe, stay prepared, and make the most of your Glock's capabilities.
