One of the best things about Glocks is that they’re one of the most upgradeable pistols in the world. There’s no other handgun that’s easier to work on and has the extensive aftermarket support that Glocks have.
SPOILER—if you want to buy just one thing for your Glock that will help you get the most from your gun, get new sights. The Ameriglo Hackathorn Night Sight Set is an excellent all-purpose sight set that will improve the performance of your Glock in any shooting context.

The Best Glock Upgrades to Put on Your Glock ASAP
We’re going to do things a little different this time. Rather than go in order of price, we’ve organized the best Glock upgrades in the order of importance, from the upgrades that you should add immediately, to those that could be considered optional.
Let’s check out these parts.
1. Ameriglo Hackathorn Night Sight Set - Glock Sights
As you may have discovered, Glocks come with plastic sights. The Ameriglo Hackathorn Night Sight Set is a great set of steel sights that work for all types of shooting.
Obviously, the first big win about these sights is that they’re steel. They’re durable enough for one-handed weapon manipulations. And they’ll hold securely in your slide for the life of your gun, whereas the plastic sights tend to warp and loosen over time.
Additionally, the steel has a better matte finish than plastic. And the backside of the rear notch is serrated. These features reduce glare and give you a blacker, crisper rear notch for faster and more precise sight alignment.
At the other end, the front sight has a high visibility insert that makes it super easy to pick up and focus on your front sight. So you can get your sights lined up and on target faster for a quicker first shot.
The high visibility front sight and flat black rear notch are ideal for defensive use.
It’s the most efficient iron sight configuration for a defensive gun. But it’s also excellent for any other sort of shooting—competition, recreation, or tactical.
So, if you’re still rocking your plastic Glock sights, grab these sights so every part of your gun will hold up to any abuse.
2. Overwatch Precision Polymer DAT Trigger Kit - Glock Trigger
Glocks are known for their mediocre trigger. It’s not terrible. But there are plenty of guns with better triggers. The Overwatch Precision Polymer DAT Trigger Kit massively improves the trigger press on your gun, without altering any of the key internals.
Since you’re not changing any springs or internal safety parts, this trigger won’t change the pull weight. All you’re really changing is the trigger shoe (the included trigger bar is a stock Glock trigger bar). So your gun remains almost entirely stock, which is necessary for competition and defensive guns in some states.
Also, the trigger shoe is the same polymer that Glock uses in their stock triggers. So the trigger surface feels about the same.
The big difference is the shape of the trigger. The flat-face trigger slightly reduces the length of pull, minimizes the travel and overtravel, and gives you more consistent trigger finger placement.
The end result is a cleaner, straight-to-the-rear trigger press. It makes it much easier to press your trigger without disturbing your point of aim. Additionally, the wider trigger face makes it feel easier to press the trigger, even though the pull weight doesn’t change.
Some shooters may prefer an aluminum trigger shoe. But the polymer will hold up just as long as a stock Glock trigger, which lasts just as long as the rest of the gun. So there’s no durability compromise.
There are trigger kits that upgrade more parts of your gun and have a more dramatic effect on the pull weight. But this trigger is easily the most improvement-per-dollar for your gun.
3. Glock Extended Magazine Release - Glock Magazine Release
The standard Glock magazine release is very streamlined, which is good in many ways. However, many shooters find it difficult to reach the magazine release without breaking their grip on the gun. Glock recognized this and produced the Glock Extended Magazine Release.
The first selling point of this upgrade is that it’s a genuine Glock part. So you know that it’s made just as well as the original magazine release. And it’s guaranteed to fit, as long as you get the one that matches your Glock model.
In terms of design, this magazine release is well thought-out.
It’s just a bit longer than the standard magazine release. So you can reliably release your magazine without compromising your grip on your gun, even if you have short thumbs.
But, Glock rounded the front edge of the magazine release. So it doesn’t catch or snag on things.
The only downside is that it sticks out far enough that you can release the magazine if you lay the gun on its side and push down on it. But this is a minor issue because the magazine doesn’t release without pressing down on the gun to actuate the release.
Overall, this extended magazine release is the most affordable ergonomics upgrade you can add to your gun.
4. Lone Wolf Distributors Extended Slide Lock Lever for Glock - Glock Extended Slide Lock
This is a minor upgrade. But it’s one that you are pretty much guaranteed to use. The Lone Wolf Distributors Extended Slide Lock Lever for Glock makes it much easier to disassemble your gun.
The stock Glock slide lock can be difficult to get a hold of when you’re taking your gun apart.
This slide lock is 3mm longer than the factory slide lock. This makes it much easier to get your fingers on, even when your fingers are oily or wet.
However, the slide lock is low profile enough that it won’t snag or scratch things.
It’s made of the same steel as the factory slide lock. And you can install this part in less than a minute.
The only thing to watch out for is the serrations on the ends. The factory slide lock has fairly rounded-off serrations.
The serrations on this slide lock are not so rounded. So it can be a bit painful if you pinch and pull down on your slide lock really hard.
Even so, an extended slide lock is one of the most affordable and easiest Glock upgrades that improves the overall experience of owning a Glock.
5. TangoDown Enhanced Slide Stop for Glock - Glock Slide Stop
Glocks are extremely well-designed, streamlined guns. There’s almost nothing to catch or snag. The downside to this is that some of the controls can be tricky to reach. The TangoDown Enhanced Slide Stop for Glock makes it much easier to use your slide stop to lock the slide open or release the slide, if you use it for that.
First, this slide stop has more aggressive serrations on the face of the lever. That way you can get a better purchase to push it up or down. This is especially helpful for those who use their slide stop to release their slide.
Also, the top edge of this model protrudes just slightly more than the stock slide stop. This makes it much easier to actuate the slide stop, even with short or slippery thumbs.
But this slide stop is still very streamlined. It won’t snag on stuff. And it fits in almost any holster just fine.
This model is stamped from 4130 steel and heat treated to ensure that it’s just as durable—if not more durable—than the factory slide stop.
So it will last as long as your gun.
Also, the finish seems to be slightly more durable than the Glock slide stop. If you’re not a fan of the classic worn silver slide stop, that’s a bonus for you.
It takes a bit more work to install than an extended magazine release. But an extended slide stop adds more ease of operation to your gun than you might expect.
6. TangoDown Grip Plug/Takedown Tool for Glock - Glock Grip Plug
The Glock grip features a hollow pocket under the palm swell. This makes the gun lighter. But it also attracts a lot of dust and dirt. And it’s unused space. The TangoDown Grip Plug/Takedown Tool for Glock keeps your grip from getting stuffed with dirt. And it uses the space for a handy tool.
In addition to the tool and sealing your frame against dirt, the grip plug has a performance benefit: it helps with reloads.
The grip plug provides a ramp that pushes the magazine into the magazine well if you don’t have it perfectly lined up. That way your magazine never catches on the back of the magazine well during a reload, even if you don’t nail the magazine insertion.
Then, this grip plug includes a takedown tool so you can completely disassemble your gun, if need be. And we mean completely. The takedown tool enables you to remove the trigger, trigger mechanism, and all the other frame components for a complete disassembly.
So, no matter what goes wrong, you can fix it.
It’s certainly not a mandatory upgrade. But it helps keep your gun clean, makes your reloads more consistent, and improves your field service capabilities. It’s an affordable way to make your life easier.
Completing the Installation
That’s it. If you’ve got yourself a bone stock Glock, it’s time to look into some upgrades. A few simple improvements to your gun can actually improve your performance with your handgun more than you might expect.
And these upgrades are super affordable. So, you can boost your performance on any budget.
If you need a place to start, get the Ameriglo Hackathorn Night Sight Set. They’re great sights that will outperform the stock plastic sights in every way.
Now that you know what you can do, get a few parts and start tinkering with your Glock.
