How We Tested the Best Glock Upgrades
Whether it be competition, concealed carry, or duty use, it is safe to say that every member of the Pew Pew Tactical team has extensive experience with the Glock platform and the various configurations and clones.
Each part on this list was evaluated based on the following criteria:
- Durability
- Reliability
- Ease of Installation
- Overall Value
Durability & Reliability
Every part on this list has been installed on one of our Glock or Glock clone.
We have fired hundreds to thousands of rounds downrange with each of these parts to assess how they affect the gun's overall functionality and reliability, as well as how well each part holds up to use and abuse.
We note any malfunctions and fitment issues, and we keep an eye out for abnormal wear patterns on any parts.
Ease of Installation
Aftermarket parts are great, but gunsmithing isn't everyone's forte.
Some parts are easier to install than others, but we wanted to avoid choosing any parts that couldn't be installed at home with reasonably proper and affordable tools.
Value
Lastly, we compare the overall performance of each part to the stock part. We then look at the upgrade cost to determine whether the performance bump is worth the price.

Best Home Defense & CCW Glock Upgrades
When it comes to guns you have to rely on to defend yourself, reliability is paramount. For that reason, I like to keep my home defense and carry guns pretty "stock."
Luckily, there are a few OEM Glock parts and other parts that I like to use that have minimal or no impact on reliability.
1. Glock OEM Extended Slide Stop Lever
I like to reload from a locked slide position using the slide stop lever. I know tons of people out there preach the slide racking method, but for me, I prefer using my thumbs to activate the slide stop lever.
It saves some time, and I always practice the same motion for my Glocks & 1911s. If anything, it gives me two options of how I want to reload.
On older Glocks, I find the flat slide lock hard to consistently activate with either thumb. When I upgraded to the OEM extended slide release, it became infinitely easier to drop the slide with my thumb.
Learn how to install it here with video and step-by-step picture walkthroughs.
2. Glock OEM Extended Magazine Release - Best CCW Upgrade
With my hand geometry and strength, I found I always had to shift my right-hand grip in order to reach the stock magazine release.
Once I upgraded to the OEM extended mag release, I was hitting the magazine release every time without losing my grip.
I take the mod one step further and sand the edges to smooth them (me and my dainty hands). I also like to sand away excess material from the bottom left-hand corner of the release to make room for my right-hand middle finger.
You can also check out our video on how to install your extended magazine release.
3. Ghost 3.5 lb Trigger Connector - Most Affordable Trigger Upgrade
The Glock trigger could be a lot better. There are plenty of complete drop-in solutions, but I wanted to keep it as stock as possible to maintain maximum reliability.
So I swapped out the stock 5.5-pound trigger connector with the Ghost 3.5-pound trigger connector.
It doesn't drop the trigger pull weight exactly by 2 pounds, but more like 1 pound and change, which is still a significant factor in making more accurate shots.
The Ghost version is supposedly self-cleaning and has run flawlessly in my Glocks.
Check out how to install the trigger connector here.
4. Holosun 507C X2 - Best Overall Red Dot
Holosun flipped the entire pistol red dot industry on its head by offering sights with 50,000 hours of battery life, selectable reticles, and shake-awake auto on/off technology.
For less than $250, you can get all of those features mentioned above with Holosun's excellent 507C X2 optic. These use a standard RMR footprint and can mount to just about any Glock that is optics-ready.
The shake-awake function and battery life are great, because if you ever have to use your pistol in a defensive situation, you know it will automatically turn on and always be ready to go.
You can check out more options and read more on our favorite choices in our Best Pistol Red Dots article.
5. Talon Grips
For a long time, I was all about doing my own stippling by running a soldering iron over the polymer grip area to make it much grippier.
You can learn how to stipple your Glock, but there is a great non-destructive method to add more grip in the form of Talon Grips.
Talon offers three texture options: a rubberized texture, a sandpaper-like granulate texture, and their "Pro" texture, which combines the rubberized and granulate textures.
I prefer the rubber type, as it's better suited for CCW and doesn't snag on clothing as much as the sandpaper-like granulate type. Here is my G19 with the rubber version compared to a hand-stippled G17.

6. Tyrant CNC Magazine Extensions - Best Capacity Upgrade
If you're running a smaller Glock, such as the G43 or G26, it's possible you may not be able to get a full grip on such a short frame. Or perhaps you just want some extra capacity.
We are fans of the magazine extensions from Tyrant Designs, as they both increase capacity while also providing more surface area to grip.
For those who just want a little extra ledge to rest their pinky on without modifying the capacity, Pearce Grips has you covered with their grip extensions.
7. Streamlight TLR-1 HL - Best Weapon Light
For home-defense guns, being able to positively identify a target in low light is extremely important. For that reason, I highly recommend a pistol light.
Our overall pick goes to the Streamlight TLR-1 HL. These lights have a 1,000 Lumen output, easy-to-use activation switches, and have a ton of holster compatibility.
If you are looking for other weapon light options, check out our hands-on article on the Best Pistol Lights.
8. Ameriglo Night Sights - Best Home Defense Upgrade
If I could choose only one essential upgrade for the Glock, it would be to replace the standard plastic U-notch sights with metal ones.
I prefer night sights for home-defense and self-defense situations since I definitely want to be able to see my sights in the dark if I am not running a red dot.
There are a ton of great aftermarket sights on the market, but I like Ameriglo night sights because they perform well and don't break the bank.
And if you are worried about installing new sights, don't worry, they are relatively easy to install yourself!
Best Competition Glock Upgrades
If you are setting up a Glock for competition use, it is all about speed, accuracy, and capacity.
Since these guns are typically not for defensive use, it is okay to push them a bit farther toward the edge. Here are some of our favorite upgrades for competition.
9. Trijicon SRO - Best Competition Optic
It is no secret that the Trijicon SRO has dominated the competition shooting scene for years. It is only in the last two or so years that there have been any red dots that have challenged it for the throne.
So why did it reign for so long, you ask? The answer is simple --- the viewing window is huge, and the optic can take a beating.
The round window is perfect for quickly acquiring and centering targets, especially steel plates. You also get clear glass and a crisp reticle, a true winning combo.
10. Timney Ultimate Builder's Kit Trigger - Best Competition Trigger
If you want the absolute lightest out-of-the-box Glock trigger for competition, the Timney Ultimate Builder's Kit is tough to beat.
Of all of the Glock triggers we tested, this one was the lightest. Using the included black spring, we recorded a feathery 2.6 lb pull. We also had the fastest split times with this trigger during testing.
But if you aren't looking to spend quite that much money, there are some other outstanding triggers as well. We encourage you to check out our in-depth article (with videos) on the Best Glock Triggers!
11. Radian Ramjet + Afterburner - Best Compensator
The Radian Ramjet barrel and Afterburner compensator combo has taken the Glock community by storm, and for good reason.
These help reduce felt recoil by up to 44% while maintaining a relatively small and reasonable form factor. You also get good accuracy thanks to the match-grade barrel itself.
But most of all, the Radian combo is reliable. Many compensators can be finicky or ammo-picky, but like most users, we have found the Ramjet + Afterburner runs extremely well with just about every type of ammo we have run through it.

12. Tyrant CNC Magwell - Best Magwell
You've probably seen flared-out additions to the bottom of the grip on most race guns.
These are magwell extensions that help your reloads become a little faster and more certain. Flared magwells offer a bigger target by increasing the size of the hole while providing angled walls to help funnel that magazine home, making reloads a snap.
I like the magwell from Tyrant CNC. It is crafted from aluminum, comes in different colors, and is easy to install on your Glock.
Installation requires a single screw into the pre-existing hole in the back of your grip. It doesn't get much simpler than that!
13. TAG Precision TSF Sights
Fiber-optic sights pull in a ton of ambient light, helping you achieve quicker sight acquisition.
I like the TAG Precision TSF sights because they let you easily swap or replace the fiber rods without having to melt or burn the ends.
Other Upgrades
14. Grey Ghost Precision Slides - Best Aftermarket Slide
Getting a customized Glock slide lets you have all the serrations, lightening cuts, and red dots mounting options your heart desires.
Our overall favorite slides are those from Grey Ghost Precision for their tight fit, increased accuracy, and sexy looks.
If you are looking for something more affordable, Brownells makes their own solid aftermarket slides as well.
We cover all the rest of our favorites in Best Glock Slides.
15. Recover Tactical 20/20 Stabilizer Kit - Best Glock Brace Kit
Want to make your Glock a little more like a carbine? There are a couple of Conversion Kits out there, but our favorite is the Recover Tactical 20/20.
It will fit all Glock 9mm models and even works with the PSA Dagger.
It stows away nicely folded up, which is perfect for a larger handgun safe that can be kept bedside or under your car seat.
Then it opens up and gives you near pistol caliber carbine (PCC) performance with a regular ole Glock.
I would opt for the 20/20NB (cheapest) kit and then add the angled mag pouch like I have above for another point of contact and ability to hold another mag.
Note that you want your red dot as high as possible, or else you have an uncomfortable cheek weld. Go with the upper rail add-on or get a high mount like this one.
16. Faxon Barrels - Best Glock Barrels
Although Faxon is known for their great AR-15 barrels, they also produce some quality barrels for Glock handguns.
Whether you just want a match-grade threaded barrel or you want an eye-catching barrel with a gold TiN or Chameleon finish, Faxon has you covered.
And yup, you guessed it. We have a Best Glock Barrels guide, too!
17. Tyrant CNC Accessories
In addition to their mag extensions and magwells, Tyrant CNC also makes some other sweet upgrade parts.
Their magazine release is the perfect length and has a super positive grip, and their extended slide release is equally as nice.
And if you are going for looks, you can even snag a matching backplate.
Final Thoughts
