Introduced in 1982, the Glock pistol had a tumultuous beginning. From the Austrian Army’s adoption to being demonized as the plastic pistol that could supposedly pass through X-ray machines undetected (it can’t), Glock inspires devotion and a certain mystique. 

Today, the Glock is one of the most popular handguns for a reason. Reliable in the extreme, simple to operate, affordable, and incredibly rugged, there’s a Glock to suit every need and occasion from concealed carry and competitive shooting to hunting. But Glock “Perfection” may be something of an exaggeration — there’s always room for improvement. 

If you’re looking for the best Glock upgrades to take your pistol to the next level, the following options are excellent contenders.

Top 7 Best Glock Upgrades Reviews

1. Glock Triggers VOGEL Competition Trigger System: Best Glock Upgrade

Glock Triggers VOGEL Competition Trigger System

Why you’ll love this:

The OEM Glock trigger could use some improvement. If you want to do it yourself, the VOGEL Competition Trigger System substitutes a lighter, crisper, adjustable drop-in replacement.

What We Liked

  • Light, crisp trigger break
  • Polished match-grade trigger system for smooth operation
  • Short trigger reset for faster follow-up shots
  • Over-travel adjustment with hex key

What We Didn’t Like

  • Listed as being for competition use only

One of the parts that most needs to be upgraded on the Glock handgun, regardless of variant, is the trigger. The stock trigger has been described, variously, as “spongy” and “squishy.” 

The drop-in VOGEL Competition Trigger System, made by Glock Triggers, is just what we need. Endorsed by its namesake, USPSA and IPSC national champion Robert Vogel, this kit substitutes a light, crisp trigger break with a short reset to allow faster and more accurate follow-up shots. It’s a crucial upgrade for either winning formal matches or self-defense

With a spring set, the VOGEL allows you to adjust the trigger weight from 3.5 to 5.0 pounds in 1.5-pound increments. All parts are polished to a mirror shine, ensuring smooth operation as the parts glide against each other. A hex key/Allen key is provided for over-travel adjustment. 

As Glock Triggers proudly proclaims, the VOGEL is approved by the IDPA and USPSA for use in all divisions

2. Trijicon HD Night Sights Set For Glock: Best Glock Upgrade for the Money

Trijicon HD Night Sights Set For Glock

Why you’ll love this:

The stock plastic sights on a Glock leave something to be desired. You should get this set if you’d prefer the durability of metal and the glow-in-the-dark tritium capability.

What We Liked

  • Tritium night sights increase visibility in low light
  • Rugged metal construction
  • Front face of rear sight allows 1-handed charging

What We Didn’t Like

  • Installation requires the help of a gunsmith

After the trigger, we should take another look at the sights the Glock ships with. The fixed OEM combat sights are commonly replaced because they’re made from plastic. If you’re anything like me, you’re also not a fan of the U-shaped white marking, which is sometimes referred to as a “goal post.” They’re adequate, but we can do better

Since the Glock is one of the most popular defensive handguns on the market, a set of replacement metallic night sights seems like a good idea.

That’s where the Trijicon HD Night Sights shine. Tritium illuminated, the HD Night Sights increase the front and rear sights’ visibility — helping you rapidly sight picture in low light. The photoluminescence of the sights is a product of their glass lamps, which contain pressurized tritium gas. 

The half-life of tritium is about 12.5 years, which means that you can get well over a decade of bright night sight use from these sights by Trijicon.

3. Glock Extended Slide Stop Lever: Best Glock Slide Stop Upgrade

Glock Extended Slide Stop Lever

Why you’ll love this:

If you’ve ever failed to depress the stock slide stop lever because there wasn’t enough surface area to swipe your thumb across, this is a simple upgrade that works.

What We Liked

  • Extended lever increases 
  • Simple-to-install drop-in replacement
  • Snag-free design grips you, not your clothing

What We Didn’t Like

  • May not be necessary for some

Third on our list of parts to upgrade is the slide stop lever. Many shooters find that the stock slide stop lever that every Glock ships with doesn’t provide enough surface area for their thumb to activate it, especially when reloading quickly consistently. After the trigger and the sights, this is worth addressing. In this case, Glock is offering the upgrade — an extended slide stop lever. 

A drop-in part, the Extended Slide Stop Lever replaces the relatively flat and serrated stock lever, which is more of a button, with an extended post that can be depressed quickly and reliably. Made from steel, the Extended Slide Stop Lever is subjected to Glock’s factory Tenifer finish, a kind of ferritic nitrocarburizing that protects against wear and corrosion. 

This part has rounded edges and is contoured to ensure your thumb grips it and not your clothing or holster. 

When fractions of a second count, you don’t want to swipe your thumb across the slide stop lever and find the slide is still locked open. 

4. Taran Tactical Innovations Firepower Base Pad for Glock 43: Best Glock 43 Upgrade

Taran Tactical Innovations Firepower Base Pad for Glock 43

Why you’ll love this:

You should get this upgrade if you’re carrying a Glock 43 because it’s slim and small but want one or two extra rounds and some additional purchase on the grip.

What We Liked

  • Increases magazine capacity and gripping area
  • Made from machined hard-anodized aluminum 
  • Available in three colors
  • Simple to install

What We Didn’t Like

  • Price may be high for a base pad

The Glock 43 is a slim, single-stack subcompact designed for deep concealment, and in that role, it performs admirably. However, by reducing the pistol’s size for concealed carry, you sacrifice both gripping surface and capacity. 

One of the best Glock 43 upgrades is one that returns some of the capacity and gripping surface. The Firepower Base Pad, made by Taran Tactical Innovations, does precisely that. Made from CNC-machined hard-anodized aluminum and available in three colors — black, flat black, and titanium gray — this base pad increases your magazine capacity by one or two rounds, depending on the model. It also adds some extra length for your little finger. 

Requiring no special tools to install, the 1-piece Firepower Base Pad, using Taran’s patented push-pin design, simply replaces the existing magazine base/floor plate. The +1 model uses the stock factory spring, while the +2 model uses a spring that’s 10% stronger.  

5. Brownells Match Grade Conversion Barrel: Best Glock 22 Upgrade 

Brownells Match Grade Conversion Barrel

Why you’ll love it:

Do you own a .40 S&W Glock 22 or 23? If you’re interested in converting it to 9mm, Brownells offers a drop-in conversion barrel.

What we liked

  • Match-grade conversion barrel
  • Precision-machined for tighter lockup
  • 416R stainless steel and black nitride resist corrosion
  • Drop-in replacement part

What we didn’t like

  • No magazine included to complete conversion

This conversion barrel is one of the best Glock 22 upgrades available.

The Match Grade Conversion Barrel, sold by Brownells, allows you to convert your Glock 22, chambered in .40 S&W, to the lower-recoiling and less expensive 9×19mm Luger cartridge. 

Made from corrosion-resistant 416R stainless steel, the Brownells barrel is machined to exacting tolerances to ensure a tight, repeatable lockup. This is sure to boost the pistol’s inherent or mechanical accuracy. Whatever corrosion the stainless steel can’t fight off on its own is kept at bay by the black nitride finish. 

A drop-in replacement part, all you’ll need to complete the conversion is a Glock 17 9mm magazine (Glock 19 when converting a 23). 

A conversion barrel is also one of the best Glock 23 upgrades, and Brownells offers one for that variant as well.

6. Faxon Firearms Threaded Compact Barrel for Glock 19 Gen 4: Best Glock Barrel Upgrade

Faxon Firearms Threaded Compact Barrel for Glock 19 Gen 4

Why you’ll love it:

If you’re looking to upgrade the accuracy of your Glock 19, or you want to try compensating or suppressing it, the Faxon barrel is a good choice.

What we liked

  • Precision machined from 4150 steel
  • Tighter lockup increases inherent accuracy
  • Nitrided finish protects against wear and corrosion
  • Threaded muzzle allows suppressor or compensator attachment

What we didn’t like

  • Stainless steel would be preferable

Maybe you’re a competitive target shooter who wants to get the most out of your gun, or you want to attach a sound suppressor and need a barrel with a threaded muzzle. In either case, a different barrel is in order. 

The Faxon Firearms Threaded Compact Barrel is one of the best Glock 19 upgrades you can find. Designed for the compact variant, this barrel is machined from 4150 carbon steel, which has been stress-relieved three times. This barrel has precision-machined engagement surfaces, ensuring a repeatable lockup to maximize inherent accuracy. To resist both wear and corrosion, the barrel is nitrided black. 

The barrel has a standard 1-in-10” rifling twist rate, which Faxon advertises as being suitable for stabilizing hard-cast lead bullets — something Glock warns explicitly against using in its factory barrels. 

As the name suggests, this barrel has a threaded muzzle designed to accommodate various accessories, from muzzle brakes/compensators that reduce recoil and muzzle flip to sound suppressors.

7. Ghost Extended Magazine Release: Best Glock Magazine Release Upgrade

Ghost Extended Magazine Release

Why you’ll love it:

You should get this extended magazine catch if you need more surface area to hit with your thumb, or you don’t want to break your firing grip during reloads.

What we liked

  • Extended magazine release for more surface area
  • Allows reloading without breaking your firing grip
  • Simple drop-in replacement part

What we didn’t like

  • Only compatible with Gen 4 Glock pistols

As with the slide stop lever, some shooters find the stock magazine catch on the Glock doesn’t offer enough material to reliably hit with the thumb, especially when done quickly. To remedy this, Ghost has introduced its Gen 4 X-Release — a drop-in replacement extended magazine catch.  

In many handguns with a horizontal push-button magazine catch, many shooters find it necessary to rotate the pistol in the strong hand to reach the catch with the thumb, altering the firing grip and taking the sights off target. 

The X-Release allows you to activate the magazine catch while keeping your sights on target and your wrist straight during reloads. You also won’t have to modify or replace the frame.

This is arguably one of the best Glock 17 upgrades, as it enables the competitive target shooter to reload faster — a plus when every fraction of a second matters.

Best Glock Upgrades Overall: VOGEL Competition Trigger System

Glock Triggers VOGEL Competition Trigger System

The VOGEL Competition Trigger System by Glock Triggers is the best upgrade on the list. As anyone who’s fired a Glock can attest, regardless of whether they think it’s good enough, the trigger can stand to be lighter and crisper

The VOGEL is a trigger system endorsed by a national shooting sports champion that takes a light trigger pull, crisp break, and short reset and combines them with user adjustability, both for weight and over-travel.
