If you’re in the market for a new Glock handgun, one of the first things you’ll have to take into consideration is the different generations within the Glock platform. This is especially the case with the Glock 19 since the Gen-3, Gen-4, and Gen-5 models are still in production to this day.
Unless you personally favor the Glock Gen-3 version of the G19, you’ll likely be torn between the Gen-4 and Gen-5 versions since they’re newer and more enhanced than their predecessor. This is when the whole Glock 19 Gen-4 vs. Gen-5 debate comes into the picture.
On that account, we’ll be taking a closer look at the Gen-4 and Gen-5 versions of the legendary Glock 19 in hopes of figuring out which version is superior. We’ll cover everything from their overall size and weight to their aesthetics and functionality, so stick around!

Glock 19 Gen 4 vs. Gen 5: Breakdown
As you can tell by reading the above-listed specifications, the Glock Gen-4 and Gen-5 versions of the G19 (designed by Gaston Glock) are almost similar on the surface. There are, however, a few key differences between the two generations that you may not notice at first glance.
Size and Weight
The Gen-4 and Gen-5 may appear similar in size, but the Gen-5 is actually a bit wider than its predecessor. Apart from that, both guns have the same overall length, height, trigger distance, line of sight, and slide design.
In terms of weight, both Glock guns weigh pretty much the same whether they’re loaded or unloaded. With that in mind, size and weight won’t be that influential when trying to choose between the two versions.
Grip and Texture
Both the Gen-4 and Gen-5 versions of the Glock 19 feature interchangeable backstraps, which means that you can easily customize your grip on either generation. The main difference here, however, is that the Gen-5 version enables you to change the grip entirely.
Another notable difference in the grip is that the Gen-5 doesn’t feature finger grooves at the front. Granted, some gun enthusiasts and long-time Glock users found those grooves useful, but others found them uncomfortable. That said, if you want finger grooves, opt for the Gen-4. If you don’t, the Gen-5 is the way to go.
As far as texturing, the Glock 19 Gen-5’s texturing is a little more aggressive than the Gen-4 version, which makes it the better option as far as optimal control. Don’t worry; it’s not too aggressive that it could cause skin chafing when pressed against your body.
Lastly, you’ll notice that the Gen-4 features a beveled rear strap and a straight-cut front strap, whereas the Gen-5’s texturing is a bit different in the sense that it runs all the way from the top to the bottom.
Trigger Mechanism
Both versions of the Glock 19 are equipped a uniform trigger that’s consistent with every shot, thanks to the use of Glock’s Safe Action System.
This fully automatic system consists of three passive mechanical safeties (trigger safety, drop safety, and firing pin safety) that operate independently to ensure a trigger pull that’s always consistent.
However, whereas the Glock Gen-4 has an active trigger, the Gen-5 has a passive one. They’re both extremely safe and reliable, but the Glock 19 Gen-5’s trigger can be a bit tougher to use.
With that in mind, we’d recommend the Gen-4 to those who are looking for the right balance between strength and accuracy. The Glock Gen-5 version is better for those who are more comfortable with a simple, bare-to-the-bone trigger.
Magazine Design
The Gen-4 and Gen-5 have the same mag release function as their predecessor, the Gen-3. Both pistols use 9mm ammo and have the same standard magazine capacity of 15 rounds. Both handguns are also compatible with several extended magazine options.
One thing you should keep in mind here is that the Glock 19 Gen-5’s magazines are a bit longer than your traditional Glock mag. This means that they won’t be compatible with a Glock 19X. With that in mind, if you’re someone who prefers total ammo compatibility, the Gen-4 is the better option.
Another thing that’s worth noting here is that the Gen-5 has a more flared magwell than the Gen-4. This makes the Gen-5 a bit easier to handle when it comes to magazine insertions.
Barrel Design
In terms of barrel rifling, the Glock 19 Gen-4 utilizes polygonal rifling in its barrel, whereas the Gen-5 uses a traditional match crown.
In our experience, the Gen-5’s barrel is more accurate than the Gen-4’s, which explains why it’s marketed as a “match-grade” barrel.
Slide Design
Both the Glock Gen-4 and Gen-5 versions of the G19 have the same slide dimensions, but there are notable differences in coating and serrations.
The Gen-5 features a proprietary finish known as nDLC. It’s said to be much more durable than the finish on previous Glock generations. It also has a deep black color to it that’s semi-glossy. We find it very appealing!
When it comes to serrations, the Gen-5 features front serrations right off the bat, whereas you need to get the special “FS” model of the Glock 19 Gen-4 to enjoy the added convenience of front serrations.
Another strong selling point for the Gen-5 version is that features an ambidextrous slide stop that right-handed and left-handed shooters will find very convenient. Overall, the Gen-5’s slide design and slide stop functionality are clearly superior.
Sight Design
The Glock 19 Gen-4 is equipped with standard polymer Glock sights. These standard factory sights are especially handy for shooting in broad daylight. They’re not that functional for night shooting, though. Luckily, these sights are easily upgradeable.
The Gen-5, on the other hand, is equipped with Ameriglo Glock Spartan Operator night sights, which are excellent for both day and night shooting. The Gen-5’s sights are also upgradeable.
Note that both versions of the legendary Glock 19 don’t come equipped with a laser. However, they’re compatible with a host of aftermarket options, so finding one shouldn’t be a problem.
Aesthetics
When it comes to looks, both versions are about the same size, shape, and weight, so you may not notice much of a difference at first glance. However, upon closer inspection, the finish is the first thing that stands out.
The Melonite coating on the Glock Gen-4 differs from the Gen-5’s nDLC coating significantly. Personally, we’re more fond of the nDLC finish. It just looks and feels more premium. Not to mention that it’s as hardy as diamond!
The thing you need to keep in mind, however, is that nDLC coating isn’t all that resistant to fingerprints. In other words, it will require regular cleaning.
Another noteworthy difference is the rounded nose and lack of finger grooves on the Gen-5. Whether or not you prefer finger grooves, their removal makes for a smoother, cleaner look.
All in all, you shouldn’t concern yourself too much with aesthetics. What’s more important is the functionality and reliability of the handgun, and both generations are highly functional and reliable.
Concealed Carry
Seeing as both pistols have virtually the same form factor, we can’t say that one is better than the other when it comes to concealed carry. They’re both highly concealable and are perfect for everyday carry whether you’re using OWB holsters or IWB holsters.
Conclusion: Which Glock Pistols Generation Is Better?
All things considered, the Gen-4 and Gen-5 versions are both excellent in terms of quality and reliability. They’re two of the most popular handguns on the market, after all, and we’re certain they’ll remain at the top of their class in the foreseeable future.
If we had to choose between the Glock 19 Gen-4 and Gen-5, we’d go with the Gen-5. There’s a lot to like about the Gen-4 model, but the Gen-5 is clearly superior. It exhibits better accuracy, has better factory sights, has a hardier finish, and its grip design is simply fantastic!
