If you’re familiar with most firearms, you are surely familiar with the Glock. That’s because Glocks are famous, well-known, and popular for a reason, but that doesn’t mean you can’t make them even better. If you enjoy upgrades and customization, Glocks are the gun to choose. They feature some of the greatest aftermarket equipment for upgrades and tweaks. 

The truth is that Glocks are cool weapons that are well-thought out and well-engineered, and they come with all of the fundamentals right out of the box. This means that none of the modifications are required to use them, but they happen to be enjoyable to install, easy to use, and of course they make your Glock simpler to operate, more dependable, more precise.

You can shoot straight and well with a factory version, but your modified pistol could hit just a touch better, and it’s also faster. Let’s take a good look at some of the best Glock upgrades on the market that can make your favorite little gun even better. 

Best Glock Upgrades

Agency Arms Red Flat-Faced Drop-I Trigger

When it comes to improving your Glock trigger, you want to have something lightweight, quick, and simple to install. The red Agency Arms drop-in Glock trigger is the ideal combination of quality and value.

This trigger is a flat-faced kit with a lacquered red finish to truly draw attention to your handgun. It’s a drop-in design, which means you can put it together in minutes without worrying about running out of parts.

The Agency Arms trigger has a notably snappier reset and a smaller and thinner trigger pull. It’s suitable for both competitive and rapid-fire shooting at the range. Because you won’t be applying as much effort on the trigger while firing, the 3.5-pound draw weight will increase your accuracy. The original trigger pull weight on a fully loaded Glock 17 is six pounds, yet the fully loaded Glock 17 weighs just two pounds. Cutting the draw weight in half will help you become a much more precise shooter.

The update preserves the crucial safety mechanism in the trigger face, which is crucial because Glocks lack a safety switch.

The flat face of this Glock trigger gives the shooter additional control throughout the pull and reset process.

It’s available in a variety of versions to suit Glocks from Generations 1-4 and 5, as well as the G43.

Key Features:

History Of The Glock

A first-generation Glock handgun, the Glock 17, was created in the 80s to participate in Austrian military pistol competitions.

The Glock 17 was introduced to the armed services pistol test as a high-capacity weapon with a magazine that holds 17 shots. It possessed a polymer-based lightweight frame, a polygonal rifling barrel which was more accurate and easier to maintain, and relatively few controls, including no safety and no decocking. A total of t hree internal safety features were included, which happen to be a drop safety and trigger-mounted safety, to name a few. With just a small number of components (34 to be exact) it could be dismantled and rebuilt fast without the use of tools.

The Austrian military handgun testing decided that Glock’s sturdy and dependable design was the best. As a result, it was designated as the P80. Following collaborative trials between Norway and Sweden, it was discovered that the Glock handgun exceeded all NATO durability criterias, prompting both nations to adopt it.

Glock established a branch in Smyrna, Georgia, in 1986. Glock pistols began to be introduced that same year and were formally released in 1988, attracting the interest of both civilian and police enforcement shooters.

By the 1990s, police enforcement agencies throughout the country were in desperate need of new high-capacity semi-automatic handguns to replace their aging.38 special revolvers. To persuade police enforcement organizations to convert to the Glock, Glock launched a comprehensive marketing effort that included significant discounts and favorable trade-in schemes. The idea was a huge success, and Glock handguns are still used by 60 to 65 percent of all police agencies in America to this day.

Glocks swept practically every important shooting activity in the civilian world. They unseated the 1911 as one of the most popular platforms for shooting competitions. Glocks are frequently recommended by experts as being appropriate for concealed carry and home defense too. Glock has even created handguns that could be used for hunting.
