What is Glock 19 Custom Slide?

The sophisticated metal coatings used in Glock handguns, “stub” slide guides rather than genuine frame rails, and an odd cocking mechanism where the trigger partially cocks the striker are all features designed to increase reliability in challenging circumstances.

The Glock 19 custom slide is a simple modification that can increase your weapon’s accuracy, speed, and performance. Several Glock 19 custom slide options are on the market, each with unique features.

One of the most popular upgrades is ported windows. These allow air to circulate the barrel and mitigate heat buildup.

What is a Glock slide?

Glock 19 custom slides are designed to add a touch of uniqueness to your gun. They’re available in various styles and finishes.

One of the most popular upgrades is the addition of ported windows, which can be found on both sides of the slide and top. These cutouts allow air to circulate the barrel, which can help to avoid excessive heat buildup.

Another option for a Glock 19 custom slide is to add additional serrations in the front. It gives a better grip on the slide when racking, even in wet or muddy conditions.

Another way to add a customized touch is to add RMR cuts designed to support red dot sights. But, again, these are relatively new features for handguns, and they’re a great way to make your Glock 19 more versatile and practical.


A bullnose is an option that instantly transforms the profile of a Glock 19 upper. It also makes the gun more functional by breaking up its square nose and giving it a more functional edge.

Another way to make a Glock 19 custom slide more functional is by adding a compensator. It is a great way to reduce muzzle flips and recoil when shooting with hand loads.

Competition shooters should consider it since it can help level the muzzle of their weapon.

It can be a significant upgrade because it can help prevent the barrel from overheating and possibly damaging its internal components. But on the other hand, it can be a substantial issue for suppressor users or those who don’t want to risk damaging their firearms.

Aside from being a significant upgrade, there are many other reasons to add a bullnose to your Glock 19 custom slide. One of the main reasons is that it is a fantastic method to showcase your high-end barrel.

Window Cuts

The window cuts are one of the most impressive and aesthetically pleasing features on a Glock 19 custom slide. These aren’t just for show; they also help reduce muzzle flips and heat mitigation.

Aside from the benefits mentioned above, this slide modification can be a fun and rewarding process. Numerous businesses carry out this kind of work. Choosing the right company is essential, as you may be modifying something that could save your life in an emergency. Additionally, a quality custom slide will last a long time and be invaluable to your arsenal.


Adding a red dot sight or optic to your Glock 19 custom slide can increase accuracy and precision. RMR (Ruggedized Miniature Reflex) sights provide quick, both-eyes-open target acquisition – even in poor lighting conditions.

When you add an optic or red dot sight to your slide, you must decide where to place the front and rear iron sights. You can relocate the show and rear irons to a position optimal for your specific application, or you can cut them out to install an RMR or red dot sight.

It also comes with distinctive cocking serrations that make it easier to manipulate the slide for check chambering or clearing jams. In addition, it has a unique “window” cutout between the front serrations, enhancing airflow to keep the barrel cooler.
