Glock is one of the most reliable names in the firearms industry, but that doesn’t mean you can’t make your Glock even better. Here are the best Glock upgrades.
A Glock is a reliable and effective sidearm that will serve you well for self-defense, target shooting, and competitions. It’s even more effective when you invest in the best Glock upgrades.
The Austrian company has won the hearts and minds of millions of Americans – as well as the disdain of many. Love it or hate it, you can’t deny that Glock revolutionized the firearms industry with their polymer pistols that have since become a go-to for law enforcement, military, and civilians alike.
Guide to the Best Best Glock UpgradesUpgrades for Your Glock
Making upgrades to your Glock will improve your shooting experience, whether you’re carrying the sub-compact G48 or the meatier G17. The main components you want to upgrade are the barrel, the grip, the trigger, the lever, and the sights.
As always, don’t settle for the cheapest option, but also don’t assume that the most expensive will be the best. Here are my recommendations for the best Glock upgrades.
Glock Trigger Upgrades
The trigger is arguably the best upgrade you can make to your Glock. There’s no easier way to improve your accuracy, comfort, and control when shooting. The factory triggers on Glock pistols have a long take up and too much overtravel and the 6-pound pull weight isn’t ideal for repeat fire.
Upgrading your trigger gives you more accuracy thanks to the lighter pull weight and improved control. Aftermarket triggers are also generally more comfortable than their factory cousins. Read our review on the Best Glock Trigger Connectors for Your Money!
If you’re on a budget or you’re only looking to make one upgrade to your Glock, make it this one.
Agency Arms Red Flat-faced Drop-I Trigger
You want to get something light, snappy, and easy to install when upgrading your Glock trigger. The Agency Arms drop-in Glock trigger in red is the perfect balance of quality and affordability.
The trigger is a flat-faced kit that comes in an anodized red finish to really make your pistol catch the eye. It’s a drop-in design, meaning you can install it yourself in minutes without having to worry about not having enough parts.
The Agency Arms trigger gives you a shorter and lighter trigger pull with a noticeably snappy reset. It’s ideal for rapid-fire at the range, as well as competitive shooting. The 3.5-pound pull weight will also improve your accuracy because you won’t be putting as much force on the trigger when firing. A fully-loaded Glock 17 weighs only two pounds, while the factory trigger pull weight is six pounds. Halving the pull weight will go a long way towards making you a more accurate shooter.
The upgrade keeps the important safety lever in the trigger face – which is essential considering Glocks don’t have a safety switch.
The flat face of the trigger allows the shooter to have more control the whole way through the pull and reset.
It comes in different models to fit Gen 1-4 and Gen 5 Glocks, as well as the G43.
- Improves accuracy
- Drop-in design is easy to install
- The stylish red finish looks great
- The flat trigger face is more comfortable
- Shorter overtravel and quick reset
- Variant for Gen 1-4 and Gen 5, plus G43
- Limited Function
- Single-stage trigger
Glock Sights Upgrades
If you’re going to pull your Glock on someone, then the chances are it’ll be at a very close range. Still, it’s essential to learn how to hit targets at a distance and place shots accurately. Shooting for self-defense requires that you can place shots on target.
I recommend you get a pair of aftermarket sights for your Glock from a reputable company that serves law enforcement or military agencies, or both.
A great pair of sights that you can use in the day or night will cover you in any situation. You mustn’t overlook illumination on your sights. You don’t want to risk not being able to shoot straight in a life-threatening situation.
Finally, opt for a pair of drop-in sights that are easy to install. Chances are you won’t be swapping them out frequently, but being able to install them yourself is still a nice bonus.
Ameriglo – Agent Night Sight Set
The Ameriglo Agent Night Sight Set for Glock is one of the best options on the market right now. How do you know they’re reliable? Because they’re the official sight set for the FBI and US Marshals, that’s how.
The sights are made from high-quality steel bar stock and have been dehorned to ensure they don’t catch on your clothes and risk making your gun get stuck when you draw it. The design also allows you to comfortably rack the slide with one hand.
The sights use a popular three-dot configuration. The front blade has a Tritium green illuminated dot circled by an orange ring, making it extremely easy to pick targets and place accurate shots, even in low-light conditions and when under stress.
The rear U-notch sight also features Tritium green lamps to help identify targets quickly and easily. The sights have a matte black finish that matches your Glock slide’s color, so you don’t have to worry about them standing out.
The sights are a simple upgrade to make, but they make a huge difference in how effectively you can aim. This is critical for proper self-defense.
Finally, the Ameriglo Agent Night Sight Set for Glock can be installed at home in just a few minutes thanks to their simple drop-in design.
- Can be used in low-light
- Experienced shooters prefer Three-dot configuration
- Used by the FBI and US Marshals
- Durable and won’t snag your clothes
- Blends in with your Glock slide
- One handed rack sliding is easy
- 12-year warranty
- Relatively affordable
- Still not cheap
Custom Glock Barrels
The barrel is one of the most commonly upgraded components of a Glock. You should certainly upgrade your barrel if you’re looking to shoot competitively, attach a silencer, use non-jacketed bullets, and improve your accuracy. This is a must for anyone using their Glock for home defense. If you’ve ever shot a gun in an enclosed space without ear protection, then you’ll understand why a suppressor comes in handy.
Glock factory barrels aren’t bad, but you can do better. One of the biggest benefits aside from increased accuracy is that you can use cheaper plated bullets with some aftermarket barrels.
The barrel you choose will depend on what you’re using your Glock for. I’ve recommended one that will suit the average shooter or anyone looking to use their gun for concealed carry. Do some more research if you’re planning on shooting competitively.
Silencerco Threaded Barrels
The Silencerco threaded Glock barrel is perfect for the recreational shooter who wants to attach a suppressor to their firearm. The Silenerco Threaded Barrel is machined from 416R stainless steel with black nitride or natural steel finish. The high-quality materials will keep your gun working smoothly for years to come and slightly improve your accuracy.
The end of the 9mm barrel has 1/2×28 threading, as well as a thread protector, so you can easily attach a suppressor and keep everything in good condition when it’s not in use.
While it’s not the most affordable upgrade you can make to your firearm, it’ll certainly improve your shooting experience and the practicality of your Glock. Note that this barrel can only be used with Gen 3 and Gen 4 Glocks. It’s an easy-to-install drop-in design, so you won’t need the assistance of a gunsmith.
- Comes in 9mm or .45 ACP
- Threaded to attach a suppressor
- High-quality build
- Choice of black nitride or natural stainless steel finish
- Drop-in design is easy to install
- Improves accuracy
- Only two calibers available
- Only for Gen 3 and Gen 4 Glocks
Glock Grip Modifications
You want to feel comfortable when holding your firearm, especially if you’re going to be putting in long sessions down at the range. This is where the Glock grip upgrade comes into play.
Not everyone likes handling the pistol’s factory grip for hours on end. This is especially true of Gen 5 Glocks where the finger grooves have been removed. While this is a plus for some shooters, others would rather have groves to rest their fingers in. Upgrading your Glock’s grip allows you to match your preferences and have a more comfortable shooting experience.
Another issue with the Glock is that the skin between your index finger and thumb can get caught in the slider. This is painful and a grip upgrade can protect you from an unwelcome pinch.
Hogue Handall Beavertail Grip Sleeves
Hogue’s Handall Beavertail Grip Sleeves are purpose-built to fit specific firearms. The company prioritizes comfort and a more natural fit for your hand. Their Glock sleeves are made to slip over the frame and their rubber material ensures that they don’t move around once secured.
The rubber used to build them is high-quality and built to last for decades to come. It won’t wear or spoil, even after years of use. It’s also great for giving you more grip, which means more confidence when shooting.
The dots and two-finger grooves on the grip help you to stabilize the weapon and make for a more natural feel when holding it. This is ideal for owners of Gen 5 Glocks who miss having finger grooves on the frame.
The grip sleeve isn’t just there for comfort, it also cushions your hand during recoil and it stops you from getting the skin between your index finger and thumb caught in the slider.
The Hogue Handall Beavertail Grip Sleeve is a quick and easy upgrade to your Glock that will make a big difference.
- Makes your Glock more comfortable to hold
- Stops you from catching your skin in the slider
- Long-lasting and well-made
- Easy to slide on and remove
- Purpose-built for your weapon
- Brings finger grooves back to your Gen 5 Glock
- No flat grip version for Glocks
Glock Magazine Ugrades
Next on the list is a very important part of a Glock or any other handgun for that matter which is the magazine. The magazine is one of the few components that have a great impact on the reliability of a firearm.
No matter the gun’s quality, if the magazine has problems, there’ll also be problems with the performance.
When shopping for magazines, you may want to consider the OEM (Original Equipment Manufacturer) factory magazine. On one hand, it may be a good option, but if you are on a budget, you may want to reconsider. The quality of Glock OEM magazines are undisputed, but they are pricey, and the money adds up pretty quickly since you’ll be needing several.
So for budget-conscious people, the choice to consider is to opt for an aftermarket magazine. This is less costly and works as good as the original.
With this in mind, you may want to take a look at the Elite Tactical Systems Group – Translucent Magazine for Glock
Translucent Magazine for Glock
Elite Tactical Systems Group – Translucent Magazine for Glock. There’s no denying the Elite Tactical Systems (ETS) Translucent Magazine is visually striking. It is built solely from polymer which is responsible for its look and durability.
Apart from the cool look, the see-through nature of the magazine lets you know if you’re running out of ammo.
ETS mags can withstand almost all abuse. Whether you drop it often on different surfaces or you kick it around, the magazine is none the worse for wear. It works smoothly like nothing ever happened.
Our Final Take
Don’t be fooled by the bold aesthetic, the ETS Translucent mag is as sturdy as they come.
Additionally, the ability to easily see the number of rounds remaining makes the mag useful at the range, during a competition, and in potentially life-saving situations.
The only downside to this fantastic accessory while it doubles your capacity, it compromises concealed carry.
- Easy to detect problems
- Highly durable, rigid polymer
- The number of ammo is visible at all times
- As reliable as the factory magazines
- Cheaper than factory mags
- Compatible with aftermarket floorplates
- May not last up to a decade like most Glock OEM magazines
If your Glock’s holster sucks, it’ll defeat the purpose of a concealed carry. Imagine a scenario where you’re facing an assailant/mugger and you need to defend yourself.
Then your worst fear comes to pass. You experience a terrible holster fail at such a critical time. This is a preventable accident and should be avoided at all costs. That’s why the first thing you should look out for in a Glock holster is how good the retention is.
In an ideal situation, your Glock shouldn’t slip out randomly when you step out of the car or bend over. The durability and comfort of a holster material are other attributes that are equally important.
Durability protects your Glock from abrasion and bumps while comfort ensures the weapon is easy as you go about your day.
These 3 major attributes – retention, durability, comfort – are the reasons why you should consider the Fobus Holster.
Fobus Holster – Evolution Holster Right Hand Paddle
Fobus Holster – Evolution Holster Right Hand Paddle has its pros and cons just like other accessories out there. Let’s take a look at some of its advantages.
The first thing you need to know about this product is that it’s an external holster. This makes it easy to put on as well as to take off. The holster features a paddle – which you probably figured out from the name.
In addition, it also stands out for other reasons.
When you slip the paddle in your trousers, it provides a secure platform that keeps your Fobus holster in place. The Safari Land Paddle is a rival holster that gives this model a run for its money when it comes to tight paddle grip.
A prominent feature to note is the paddle’s raised edge, which rests below the belt and prevents the holster from detaching easily. Another advantage of the raised edge is it significantly reduces wear and tear.
Fobus really meant business with this model as you can see from the holster retention. The Right Hand Paddle comes with a retention screw you can adjust to your convenience.
N.B: At this point, we ask that you don’t tighten your holster to the point that it’s hard for you to make a fast draw in an emergency.
To further strengthen the retention ability of the holster, the model has a non-slip rubber surface that stops accidental slip-offs.
Lastly, on the rubber surface is a nice padding that makes the holster comfortable to carry.
Our Final Take
Fobus Right Hand Paddle is developed from a Kydex material that equips the holster with its durability.
The toughness, alongside its comfortable fit and superior retention ability make this holster stand out. As for the cons, the common complaint we occasionally hear about the Fobus Right Hand Paddle is how it doesn’t work under untucked shirts.
When a gun is removed and reholstered, the untucked shirt goes right inside the holster, causing more tightness and making it hard to draw the gun again.
If your shirts are often tucked in when you carry or if you can create the time to hold your shirt when you reholster, there should be no issue.
- Rubber paddle backing for comfort and extra stability
- Compact / Lightweight design
- Doesn’t sweat or breathe. (Doesn’t need oiling either)
- Lifetime Warranty
- Retention adjustment screw
- Passive retention
- Reinforced rivet attachment
- 1-piece holster body construction
- Low-profile design for concealability
- Protected sight channel
- Untucked shirts tend to slide into the holster while reholstering, causing extra tension when you redraw.
Glock Lever Upgrades
The lever is a small and very cheap upgrade for your Glock. It’s also one that’s greatly overlooked due to its modest size. Upgrading the slide lever on your Glock is a quick and simple way to make stripping down your gun much easier.
I recommend you get an extender lever to make it easier to grip. This is the main feature to look for in an upgraded lever. Good quality materials are a must, although the cheap cost of this part ensures that anyone can afford the highest quality parts.
For such a small and unassuming upgrade, the slide lever can make field stripping your Glock much easier, even in bad weather.
Lone Wolf Extended Slide Lock Lever
The Lone Wolf Extended Slide Lock Lever for Glock is a must-have upgrade if you’re looking to make your life easier when it comes to field stripping your weapon. It’s a cheap and cheerful solution and an easy one to tick off the list when upgrading your Glock.
The lever is made from high-quality steel to ensure durability over time. This is a part prone to wearing down with use, so it’s important to have one that will stand the elements’ test.
The Lone Wolf slide lock lever is 3mm longer than the Glock factory variety, making it easier to use when stripping down your pistol. You might not think that this is necessary, but operating the slide lock lever can be difficult when your Glock needs stripping out in the field and you have dirty or wet hands.
You don’t need the help of a gunsmith to install this part. It’s a drop-in design so you can do it yourself in just a few minutes so long as you follow the instructions closely.
The Extended Slide Lock Lever for Glock is made in the USA, so you can count on it to be high-quality and built to meet the expectations of the world’s proudest gun owners.
- Easy to install
- Makes field-stripping your Glock easy
- Made in the USA
- Solid construction
- Extended length for ease of operation
- Not entirely necessary for Gen 5 Glocks
If you’re only going to buy one upgrade for your Glock, then make it the Agency Arms Drop-In Trigger. Upgrading your Glock trigger gives you more control and comfort when shooting and a lighter trigger pull weight will improve your accuracy.
The snappy reset of the Agency Arms trigger, coupled with the 3.5-pound pull weight, will make your Glock much easier to shoot and will allow you to have more confidence when you need it most.
This isn’t a cheap upgrade, but it’s worth every penny. Most of the other upgrades on this list can be added on as side bargains anyway, so it’s worth splurging out on the trigger upgrade as your main point of focus.
