The Glock 19 is a popular handgun, and for good reason: it’s a compact handgun chambered in a great defensive caliber. This is a pistol that’s durable, reliable, and definitely capable of withstanding serious use. Of course, if you have a Glock 19, you might want to make a few aftermarket changes, and we’re here to help. These are the top 19 modifications & Glock 19 accessories you might want to make to your favorite handgun—and why.
1. Zaffiri Precision Ported Barrel
Why a ported barrel? Because a quality design like the Zaffiri Precision Ported Barrel is made to reduce muzzle rise and create a flatter shooting experience. That means you get greater accuracy on target as well as less felt recoil, and who doesn’t want that? This barrel is made for Gen 5 models and has a black nitride finish to make it resistant to wear, so it lasts longer.
2. L2D Combat Precision Match Fluted Barrel
Maybe you don’t want a ported barrel, but you do want one made for reduced weight and faster cooling during high round count days. The L2D Combat Precision Match Fluted Barrel is compatible with Gen 2/3/4/5 Glock 19s, and it’s designed to outperform your factory barrel. This barrel is manufactured with tight tolerances and numerous features that improve accuracy. Tighter groups and consistent shot placement are in your future with this barrel (and a little training). Want a threaded barrel so you can add a muzzle device quickly and easily? Try the threaded variant.
3. Tyrant Designs T-Comp Compensator
Having a good compensator on your Glock 19 is a great way to reduce felt recoil and cut down on muzzle rise. A lot of shooters prefer a compensator to a ported barrel for this purpose—or utilize both for even better performance. The Tyrant Designs T-Comp Compensator works with Gen 4 models and is threaded for 1/2×28 (check with the manufacturer if you’re not sure how your barrel is threaded). According to the manufacturer, this compensator on your Gen 4 Glock 19 will fit in a holster for a Glock 34, but you need to be aware that it will likely mean less retention and a looser fit within the holster itself. Tyrant Designs also offers this compensator for your Gen 5 Glock 19.
4. Strike Industries Modular Magazine Release
The magazine release on your handgun might not be as tactile or easy to operate as you want. That’s where something like the Strike Industries Modular Magazine Release comes in, giving you an aftermarket release that’s also offered in different colors. This model is also created to make your mag release more smoothly. It’s compatible with Gen 4/5 Glock 19s and has a polymer body for longevity.
5. Rainier Arms Ambi Mars Magazine Release
If you’ve ever had to adjust your grip to manipulate your gun’s mag release or wished it wasn’t one-sided, you’re in luck. The Rainier Arms Ambi Mars Magazine Release is made to be operated with your index finger instead of your thumb, helping you keep your grip in place during live fire. It helps smooth out and speed up mag changes, which is great whether you’re plinking or focused on self-defense tactics. This mag release is offered in a few colors and is compatible with Gen 4/5 Glock 19s. If you have a Gen 1-3 gun, they make a release for that, too.
6. Tyrant Designs Extended Slide Glock 19 Accessories
The Tyrant Designs Extended Slide Release is meant to make using your slide stop easier. You’ll notice that the use of “slide release” versus “slide stop” often depends on the manufacturer, but it refers to the same part. This part of your gun is meant to lock/stop the slide. Overuse of the slide stop to slingshot the slide forward can be damaging to your handgun. This model is made for Gen 2/3/4 guns and comes in a variety of colors. If you have a Gen 5 you want to upgrade, there’s also a model made for that generation.
7. DPM Systems Technologies Firing Pin Spring
You’re probably wondering why you’d want to swap out your firing pin spring, and we’re going to tell you why. The firing pin spring on your Glock 19 could wear out from extensive use, creating a less reliable gun, or maybe the factory spring just isn’t as well-made as you’d prefer. Or maybe you’re changing your trigger and want the smoothest, most reliable setup possible. The DPM Systems Technologies Firing Pin Spring comes in three lengths and works with various trigger pull weights, meaning it’s versatile. The shortest spring is 5 pounds, the medium-length spring is 6 pounds, and the longest spring is 7 pounds. This spring is compatible with all generations of the Glock 19.
8. Tactical Springs (Sprinco) Recoil Spring
The recoil spring on your Glock 19 is a component that can wear out or need changing for better cycling with different weights of ammo. It can also help you change your recoil spring if you’re trying to create the smoothest shooting gun possible. Tactical Springs (Sprinco) Recoil Spring is available in three different weights: 15-pound blue for enhanced power, 13-pound green for standard power, and 18-pound red for extra power. The manufacturer lists this spring as rated for between 5,000 and 50,000 rounds. Because it’s a recoil spring, it will work with any generation of the Glock 19.
9. Handleit Grips Edge Grip Kit
If you’re interested in a more aggressive grip surface but would prefer not to permanently alter your gun with stippling, check out the Handleit Grips Edge Grip Kit. With an aggressive grip surface, you can maintain your hold on the gun more reliably, even with wet hands. That means both better results on target and a more reliable grip in a high-stress situation. This grip decal works with the Gen 3 but is also offered for the Gen 4.
10. Tactical Springs (Sprinco) Recoil Management Guide Rod System
Sometimes, replacing just the recoil spring isn’t enough, whether due to personal preference or wear on the gun. If you’d like to change out both the recoil spring and the guide rod—the latter of which helps keep the spring moving reliably, among other things. A good guide rod and spring combo can give you a flatter-shooting gun that cycles more reliably and lasts longer. The Tactical Springs (Sprinco) Recoil Management Guide Rod System comes with everything you need to enhance and fine-tune your Gen 3-4 Glock 19 including three spring weights—13 pound, 15 pound, and 17 pound.
11. DPM System Technologies Mechanical Recoil Reduction System
With the right aftermarket system, you can make your Glock 19 recoil less and produce less muzzle rise. That means your shots on target are more consistent, and groups are tighter. The DPM System Technologies Mechanical Recoil Reduction System is a unique setup created to give you a flatter shooting gun for a comfortable, accurate shooting experience. It has multiple springs, including one inside the guide rod, all of which work together for faster follow-up shots and noticeable recoil reduction. This system is compatible with Gen 4 and 5 Glock 19s.
12. Apex Tactical Specialties Failure Resistant Extractor
Reliability is something you should demand from your Glock 19 accessories, and it’s even more vital if it’s on your carry gun. The extractor, which is the component that removes spent brass, can wear out, break, or simply not work as well as it should. To fix that issue, simply install the Apex Tactical Specialties Failure Resistant Extractor. This kit includes the extractor itself as well as an aftermarket extractor spring. It’s compatible with Gen 4 guns and made for use with the Glock factory slide and barrel. Of course, there’s also an extractor kit for Gen 3/4/5 Glock 19s.
13. Magpul Enhanced Mag Well Glock 19 Accessories
Sometimes, you have sticky mags or trouble getting ahold of the magazine during mag changes. Whatever is slowing you down, the solution can be as easy as installing a Magpul Enhanced Mag Well. These aftermarket Glock 19 accessories are made of polymer for durability and create an easier-to-manipulate working surface around your gun’s magazine well. That means faster mag changes and smoother operation overall. Adding this creates a flared magazine well that can take your mag changes to the next level. This product is made for Gen 4 guns.
14. Nomad Defense Magwell Extension and Backstrap Combo
Changing out the backstrap on your Glock 19 can create a grip shape that fits your hand better, translating to greater comfort and accuracy. Add in a swap of the gun’s magazine well, and your mag changes will speed up and smooth out. This kit is made to be compatible with the Nomad 9 frame, which is an aftermarket upgrade for the Glock 19. It’s a great way to enhance your gun further and customize the frame to fit your hands better.
15. Radian Weapons Glock MOS Guardian Optic Guard
Running a red dot on your Glock 19, or do you want to? The Radian Weapons Glock MOS Guardian Optic Guard is designed to help protect your favorite Glock 19 accessories from damage while providing backup, low-profile iron sights. The mounting plate is compatible with red dots and a Trijicon RMR footprint. This accessory is a great way to protect the red dot you invested in and also keep it going in harsh environments. It’s made for Glock MOS systems and comes in black.
16. Apex Tactical Specialties Ultimate Safety Plunger
The safety plunger on your Glock 19 is a small component that’s often overlooked but important. This part is for the trigger, and using an aftermarket model like the Apex Tactical Specialties Ultimate Safety Plunger can smooth out the trigger while keeping the internal safety mechanisms intact. Having a clean, smooth trigger pull is important for trigger control and accuracy, and replacing the safety plunger is one way to get there. This is a drop-in part that doesn’t require gunsmithing. It’s compatible with Gen 2/3/4 guns.
17. Tyrant Designs Diamond Cut Frame Pins
Replacing the frame pins on your Glock 19 can significantly increase the longevity of the parts while also creating a platform with superior stability. Tyrant Designs Diamond Cut Frame Pins kit includes pins to replace the locking block pin, trigger pin, and trigger housing pin. It’s compatible with the Gen 3 Glock 19. You don’t need to wait for a pin to wear out, break, or come loose before replacing them. Sometimes, it’s the seemingly tiny part changes that make the most significant difference.
18. Empire Yumi Micro Glock 19 Accessories Charging Handle
You might be thinking charging handles are only for AR platform rifles, but they’re made for handguns, too. The Empire Yumi Micro Charging Handle is meant to make manipulating the Glock 19’s slide easier. It can be a fantastic tool for shooters with injuries or weak hands. This charging handle is compatible with all generations of the Glock 19. It’s available in black, so it blends in with the standard factory color, and it is incredibly lightweight so that it won’t throw off the balance of your gun.
19. Tyrant Designs Two Piece Sights for Glock
Changing the iron sights on your Glock 19 can make a huge difference in overall performance. Tyrant Designs Two Piece Sights are made to draw the eye to the front sight to improve target acquisition and accuracy. They’re designed to be glare-free and rugged, which is an important feature for sights. And thanks to their smooth profile, they’re resistant to snagging and less likely to scrape the interior of your holster. These sights are compatible with all generations of the Glock 19.
