Glock 43 vs 19: A Detailed Comparison

Listening to user feedback and building on what Glock learned over the years, Glock worked out the kinks, made some changes, and followed up with the 9mm G43 in April 2015, which was an immediate success. It was a good seller then and continues to be today, making it a key model in the Glock 19 vs 43 debate.

Four years later, at Shot Show 2019, Glock announced the G48, and again they were targeting the concealed carry market. Intended to be the do-everything pistol, the G48 is a compact Glock that’s a bit like a scaled-up G43 (or maybe a Slimeline G19?).

It adds more capacity and a longer slide, giving you, on paper, a pistol that’s small enough to conceal but big enough to shoot accurately.

At the same time, they also released the Glock 43X, which shares a frame and has the same grip as the G48 but uses has shorter barrel and slide, so the only real difference between the two is the slide length.

About Slimline

You may have noticed that these Slimline models don’t adhere to a particular generation of Glocks. The G36, G42, G43, and other Slimline Glock models are categorized by their Slimline status, rather than any specific generational features. In fact, Glock lists the Slimline products in a dedicated category on their site. The more you know…

Frame and Grip Design

The frame and grip design of a pistol are crucial factors in determining its comfort, ergonomics, and overall shooting experience. Both the Glock 19 and Glock 43 have a polymer frame, but they differ in terms of size and texture.

Similarities

Since we’re talking about Glocks, especially Glocks released in the past 10 years, there’s going to be a lot of overlap between these two pistols, from their chambering to cerain design choices. Here’s how they’re alike:

• Slimeline build: Both are part of Glock’s Slimline lineup designed for concealed carry.
• Chambering: Both are only chambered in 9mm
• Semi-Automatic Action: The G43 and G48 are semi-automatic handguns that use Glock’s Safe Action trigger system.
• Plastic Sights: They both come with Glock’s standard three-dot fixed sights
• Beavertail Grip: Both have a similar grip design with built-in beavertails
• Reliable Service: They share a record of reliable, consistent performance

Differences

The Glock 48 is surprisingly snappy for the size of the gun. It’s certainly better than the G43, but not as good as most would expect. It handles like a small gun despite the effort Glock put into making it controllable.

The thin frame and slim grip concentrates recoil impulse into the beavertail, which produces more muzzle rise despite the G48 being a larger Glock than its G43 relative.

The built-in beavertail is there to mitigate some of the recoil, but I feel it most in the web of my shooting hand. It’s not a deal breaker–just one of the trade-offs for a streamlined concealed carry gun.

The longer sight radius did help me shoot with reasonable accuracy at 3 yards. I started dropping shots when I took it out to 10 yards. After I shoot mine for a while, the trigger begins to feel heavy, and I anticipate the recoil.

The G43 has the older standard Glock barrel, while the G48 comes with the Glock Marksman Barrel (GMB). The GMB improves the rifling and is designed to improve accuracy. The longer barrel of the G48 also contributes to improved accuracy, making it a better choice for those looking for enhanced firearm performance.

The extra length in the G48 barrel means you eek out a touch more velocity with your shots, which may not matter much in terms of improving accuracy (we’re talking about pistols designed for use within 20 yards here), but the higher muzzle velocity does help with hollow point expansion, which means you can stop threats faster.

Winner: Glock 43

The Glock model 43 and model 48 are Slimline pistols that use single-stack magazines, making them great for concealed carry, with the biggest difference being their relative size.

The G43 is 1.06 inches wide, and the G48 is slightly wider at 1.1 inches. Compared to thicker double-stacks, these two are small guns that are easy to conceal for most people, although their Slimline builds mean you can’t use double-stack mags from non-Slimline Glock models.

Despite being a smaller Glock, the G43 feels surprisingly good in the hands. It’s small, though, and most people probably can’t get their pinky on the grip with a flush magazine.

If that’s the case, I’d suggest getting an extended magazine because the pinky is important for control. It’s small enough that it works well in standard carry positions or deep concealment type pocket or ankle carry. All things being equal a smaller gun will carry more comfortably for most people.

The texture on the G43 could be better. It’s great for concealed carry because it won’t tear up your shirts or skin. But it doesn’t take long to feel like you’re slipping when shooting. I’ve had grip tape on mine for years, and it works.

Although it’s not very ergonomic, I like the way the Glock 48 feels in my small hands. The slim grip feels good and allows me to reach the trigger easier than I would on a Glock 19. Similarly, my husband likes the feel too. This is one pistol that services different hand sizes equally. Many gun owners appreciate the ergonomic design of both models for different reasons.

The grip size is much better for drawing from concealment than the Glock 43. You can get a better purchase on the gun right out of the holster, be it an IWB or OWB holster, but its size puts it more in the waist or appendix carry range than the G43.

The G48 has Glock’s raised squares texture, falling somewhere in the middle on the aggressiveness scale. Once your hands get sweaty, you’ll want something more like the grip tape I use on mine.

It’s also 2.5-3 ounces heavier than the G43, which may not make a huge difference overall by may impact your decision to carry the G48 in certain ways.

They both feature the standard black-polymer Glock frame. And the 43 frame, although slightly more rounded on the back, looks like a shrunken-down version of the 48. They both have built-in beavertails but the G48 has a slightly longer grip to accommodate the 10+1 mag.

Winner: Glock 43

These two pistols are both excellent options for concealed carry, but for me, they serve two distinct purposes. If maximum comfort is the deciding factor, I love carrying the G48 when I can. Its slightly longer slide and grip means there’s more to conceal in both directions.

If it’s all about concealment and wardrobe flexibility, I know I can conceal the G43 in any outfit I own. That said, both models are popular choices for personal protection due to their concealability.

I carry the Glock 48 in every season with the exception of summer when I need something that can easily be concealed in warm weather clothing. I prefer the Glock 48, but if I could only have one, I’d choose the G43 because it’s effortless to conceal.

That said, I’m all of 5 foot 1, so larger humans probably won’t struggle to carry the G48 year-round.

Winner: Glock 43

My biggest complaint with the G43 is the 6+1 capacity, but at the time, that was good. Remember, this gun came out in 2015. You can get up to 15+1 in certain aftermarket extended magazines, but that kind of defeats the purpose of carrying a small pistol. A +2 extender is still easily concealed.

When comparing glock 43 vs Glock 48, the Glock 48 comes with a 10+1 round magazine which may seem low to some. You can pick up the S15 magazines by Shield Arms to increase capacity if ten rounds doesn’t feel like enough. The G48 offers more capacity than the G43 and a MOS version with optics and rail support if you want to run a red dot.

Winner: Glock 48

The Glock 43 is cute. There, I said. It looks like a baby version of other Glocks with a little more rounded backstrap. There are no frills, but it looks good for a subcompact and is finished with the same quality as any other Glock models.

Glocks always have a utilitarian look, which I don’t mind. The G48 looks streamlined with its slim profile. I like that they included front serrations, which are missing from the G43.

Winner: Glock 48

The 43 is reliable and exactly what you’d expect from Glock. I’ve been shooting my G43 for nearly eight years, and I’ve had very few issues. A rare malfunction here and there that can usually be chalked up to an aftermarket magazine or my grip wearing out.

Glocks have always been reliable and have a good track record of consistency. With about 1,000 rounds through my G48, I’ve had zero issues. It takes any ammo I feed it and always shoots as expected. This one’s a draw.

Winner: Draw

Trigger Pull

Ahhh, Glock triggers. What can I say? They’re in between good and not good. The G43’s pull is heavy for a small pistol. I’ve polished mine to help a little, but I can see why people are always hunting for aftermarket triggers. That said, it works fine and consistently.

There’s a short take-up on the G43 before you get to the wall. After that, there’s a little bit of creep before the break. And then a positive, short reset you can feel. With practice, you can shoot the G43 pretty quickly.

The G48 also has a short take-up, but it feels heavier. When you get to the wall, there’s a rolling break and some resistance. Again, the reset is short and positive, and you can feel it.

Winner: Glock 43

Sights & Optics Support

Both the 43 and 48 come with Glock’s plastic filler sights that they know people will upgrade with night or aftermarket sights. You can also choose to upgrade to an Ameriglo option from the factory. These are night sights with a blacked-out rear u-notch and either an orange or yellow dot front sight.

The Glock 43 doesn’t have a MOS version, but the G48 does. Because it’s a Slimline pistol, it can take a micro-reflex optic like the Holosun 507k or Shield RMSc mounted with a plate. The G48 MOS version also supports red dot optics for enhanced shooting precision. Of course, you can always have a slide milled for an optic too.

The G43’s shorter sight radius means it can be a challenge for some users to acquire targets quickly, especially those who are used to larger pistols, but the short stature is a common compromise when considering a compact pistol.

Winner: Glock 48

Slide, Rails & Accessories

The Glock 43 has a basic Gen 4 slide, so there are rear serrations but none at the front. Adding front serrations would have been nice because Glocks can be tight to rack until they break in, and the small slide is a challenge to gain purchase to begin with.

Glock included front serrations on the G48, although I wish they were slightly deeper. If you want features like an accessory rail and optic-cut slide, opt for the Glock 48 MOS because those are missing on the original G48.

Neither of these is available on the G43, which gives the nod in the features category to the G48. For a G43-sized pistol that offers the rail and optics support you’ll need to look into the G43X.

Winner: Glock 48

Since the Glock 43 was released, a lot has changed in the subcompact market. Namely, manufacturers like Sig Sauer are getting more rounds in smaller guns.

Still, the G43 is a good value. It’s affordable, reliable, and easy to conceal, everything I want in an everyday carry gun.

The Glock 48 isn’t loaded with fancy features like other guns, but that’s the trade-off for the affordable price. If you’re looking for a simple pistol that will function with very little maintenance, it’s a good choice.

Of course, you can do all kinds of upgrades to make it your own. Aftermarket parts aren’t cheap, but they are generally in heavy supply for the 48 and all Glocks.

This is another draw.

Glock 43

Glock 48

Let’s start with the scores by category:

Both the Glock 19 and Glock 43 are excellent pistols for concealed carry and personal defense. While they share many similarities, they also have distinct differences in terms of size, capacity, and features.

The Glock 43 is more suitable for concealed carry and smaller hands, offering a compact and easily concealable option for everyday carry. On the other hand, the Glock 19 is more suitable for home defense and personal protection, providing a larger frame and higher capacity for those who prioritize versatility and performance.

Ultimately, the choice between the two pistols depends on your individual needs and preferences, but both the Glock 19 and Glock 43 are reliable and effective options for personal defense and home defense.

So, which is a better choice between the G43 and G48?

That’s a tough question to answer, so I bought both! And it’s not difficult to see why; based on the numbers, it’s a toss-up. Both the Glock 43 and Glock 48 took 4 categories outright and drew twice. But that is my personal experience.

For me, the two guns serve a dedicated purpose — I prefer to carry the G48 but when the weather turns warm it can be challenging to conceal for me, so I turn to the G43 which I can easily conceal with any outfit.

That said, I am a petite woman. If you’re bigger than my whole 5-foot, 1-inch self, you can likely conceal the Glock 48 all year round. In that case, pair it with the Shield S15 magazines, and you have yourself a solid concealed carry setup.
