Glock 19 Upgrades

Glock is one of the most popular pistol brands in the world. Law enforcement agencies, Militaries, and civilians in the US and worldwide use Glock pistols for their simplicity and extreme reliability. However, one of the biggest reasons for the incredible success and following of Glock pistols, especially among civilian shooters, is the aftermarket support.

Glocks easily have the best aftermarket support in the US market. You can make loads of different upgrades to your standard Glock, making it a very versatile firearm. Many people also build Glock pistols with parts kits.

Glock 19s are especially popular among shooters, and here are some of the popular Glock parts that shooters can use to build or upgrade their Glock 19.

Popular Glock 19 Upgrades:


Of course, the barrel is an essential part of any pistol, and there are many brands that make really high-quality barrels for Glock 19s. Some barrels might be fluted to lose weight, and some come in a wide range of finishes to add to the aesthetics of a Glock 19, which works great, but in its stock form, is not the prettiest pistol. Brands like L2D Combat and Faxon make some incredible Glock 19 barrels.


When it comes to improving the aesthetics of a Glock 19, the slide is one of the biggest upgrades you can make. Many aftermarket slides feature lightning cuts and improved serration designs. Slides are also available in a wide range of cool finishes, which can add to the aesthetics of your pistol.

However, one of the most popular reasons many people opt for aftermarket Glock slides is red dot sight compatibility. Most competitive shooters who use Glocks like to have lighter slides that cycle faster and the ability to use red dot sights for faster shooting.

Extended Slide Release

Many shooters, especially those who want to be quick, opt for extended controls on their pistols. An extended slide release allows shooters to engage the slide release more efficiently and reliably, even when wearing gloves or having wet hands. Extended slide releases are also used by competition shooters, as they can help them reload their Glock 19 more quickly.


Glocks are very reliable pistols; however, one of the things that most people don't like about them is the sights. They are usually made from plastic and don't offer a great shooting experience in low light. This is why many people choose to upgrade their Glock sights and use night sights or fiber optic sights instead.


Typically, Glocks have good triggers; however, they are a bit on the heavy side since Glocks are primarily designed as law enforcement and military sidearm. Luckily, loads of competition and adjustable Glock triggers are available in the market. These triggers are great for faster and more accurate shooting.


Magwells are designed to guide a magazine into the pistol more easily and naturally. They are an excellent Glock 19 upgrade and are used by most competition shooters.

Extended Mag Release

An extended Mag release also serves a similar purpose as an extended slide release or magwell. They are designed to make the controls of your Glock faster, allow quicker reloads, and help you clear malfunctions more quickly. These upgrades can make you an overall faster shooter.

Flashlight and Laser

Flashlights and Lasers are another excellent Glock upgrade, and any home defense Glock needs to have a good flashlight on it. Lasers are also great for home defense pistols, and they are also used by law enforcement and special police units.
