About Glock

Glock is a famous firearm brand founded by Austrian engineer Gaston Glock in 1963. They initially worked as a plastics manufacturer and was asked by the Austrian military to develop a new pistol to replace their existing firearms. Glock had no experience with firearms, but he used his knowledge of plastics to create a new lightweight and durable pistol.

The first Glock pistol, the Glock 17, was introduced in 1982 and quickly gained popularity worldwide among law enforcement and military personnel. The Glock 17 was a revolutionary design, as it was the first pistol to use a polymer frame instead of the traditional metal frame. This made the gun lighter and more durable, as the polymer was resistant to corrosion and could withstand extreme temperatures.

Over the years, Glock has continued to innovate and expand its product line. For example, the company has introduced new models of pistols, including the Glock 19, Glock 26, and Glock 43, each designed for a specific purpose. Glock also produces firearms for law enforcement agencies, military units, and civilians.

Glock’s success has not been without controversy. The company has been criticized for its aggressive marketing tactics. Despite controversies, Glock continues to be a famous brand among firearms enthusiasts and remains one of the most successful firearm companies in the world.

Barrel & Slide

The 43X features a 3.41-inch barrel made of cold-hammered steel, which has been treated with a Tenifer finish to enhance its durability and corrosion resistance. This barrel is designed to provide consistent accuracy and muzzle velocity, making it ideal for self-defense and target shooting.

Glock 43x slide

The slide of the Glock 43X is also made of steel and features a black oxide finish. This finish helps protect it from wear and tear over time. In addition, the slide is designed for cycling smoothly and reliably, allowing for quick and easy follow-up shots.

Glock 43X’s slide features front and rear serrations, which provide an additional gripping surface for manipulating the slide. This can be especially useful when the shooter’s hands are wet or sweaty or when wearing gloves.


Let’s keep it real, the Glocks finish isn’t going to win any “Gun Finish Pageants,” but you likely knew that when you bought it. What the 43X delivers in this arena is a practical, durable, hardy finish.

The finish of the Glock 43X is designed to protect against wear and tear, corrosion, and other forms of damage that can occur with regular use. The slide of the Glock 43X is finished with a black oxide coating, which is a chemical conversion process that converts the surface of the steel slide into a blackened oxide layer. This layer provides a degree of protection against rust and corrosion and also helps to reduce glare and increase resistance to wear.

Glock 43X finish

In addition to the black oxide finish on the slide, the Glock 43X also features a Tenifer finish on the barrel. Tenifer is a nitriding process that hardens the steel and makes it more resistant to wear, corrosion, and other forms of damage. In addition, this process creates a dark gray matte finish that provides a durable and long-lasting layer of protection against wear and tear.

The black oxide finish on the slide and the Tenifer finish on the barrel provides a durable and reliable finish for the Glock 43X. This finish protects it against the elements and other forms of damage. Additionally, the finish is easy to maintain, allowing owners to keep their Glock 43X looking and performing its best with minimal effort.


The frame on the Glock 43X is made of a polymer. It will withstand the wear and tear of regular use while providing a comfortable and secure grip. Additionally, the frame of the Glock 43X features a textured surface that enhances the shooter’s grip and offers additional control when firing the pistol.

Glock 43X Semi-Auto Pistol

One of the critical features of the Glock 43X’s frame is its size. The frame of the Glock 43X is just the right size to accommodate the magazine and slide while also providing enough room for the shooter’s hand to grip the pistol comfortably.

Another critical aspect of the Glock 43X’s frame is its ergonomic design. The frame has a beavertail extension, which helps to prevent the hand from slipping up and over the back of the pistol during recoil. This extension also helps to reduce felt recoil, making it easier to control the gun and maintain accuracy when firing.

In addition, its lightweight, durable polymer construction and ergonomic design make it a top choice for concealed carry.


An essential aspect of any handgun is the grip, and the Glock 43X’s grip is no exception. The grip of the Glock 43X compact has a comfortable and secure hold. In addition, it’s a polymer that is lightweight and strong. In respect of “beauty,” the 43Xs grip, again, isn’t going to win any awards. However, their textured surface provides a solid, comfortable grip and is efficient and functional.

Glock 43X Grip

One of the critical features of the Glock 43X’s grip is its size. The pistol is compact and lightweight, making it ideal for concealed carry. As a result, the grip of the Glock 43X is just the right size to accommodate the shooter’s hand while also providing enough room for the magazine and slide.

Designed with a finger groove and a palm swell that conform to the hand, they provide a comfortable and secure hold.

Additionally, the grip angle of the Glock 43X places the handgun in a natural point of aim, making it easier to maintain accuracy when firing.

The grip can be customized with different backstraps to adjust the size and shape of the grip, and the grip texture can also be modified to provide a more aggressive or smoother surface.


Glock 43X’s magazines are single-stack designs that hold up to 10 rounds of 9mm ammunition. This capacity is sufficient for most self-defense situations and provides the shooter with enough rounds to defend themselves in an emergency.

Glock 43X magazines

One of the key features of the Glock 43X magazine is its construction. The magazine is made with polymer. The polymer construction also helps keep the magazine’s weight down, making it easier for the shooter to carry and handle the pistol.

The magazine baseplates can be removed for cleaning and maintenance.

Finally, the Glock 43X magazine has a variety of customizable options available. Aftermarket magazines are available with different baseplates, extensions, and followers, allowing shooters to tailor their magazines to their preferences. This can include extended magazines, finger extensions, and different baseplates for improved grip and control.


The Glock 43X has several safety features to help prevent accidental discharge and ensure the firearm is safe to handle. They include.

  • Trigger safety: This safety mechanism prevents the trigger from being pulled unless the shooter applies pressure to the center of the trigger. This helps to prevent the trigger from being pulled accidentally or without the shooter’s intent.
  • Firing pin safety: It blocks the firing pin from striking the primer unless the trigger is pulled completely to the rear. This helps to prevent the firearm from discharging if it is dropped or if the firing pin is struck accidentally.
  • Drop safety mechanism: This prevents the firearm from discharging if it is dropped or subjected to impact. This is accomplished by a mechanism that blocks the movement of the firing pin until the trigger is pulled.
  • Loaded chamber indicator: This allows the shooter to check whether there is a round in the chamber visually. This indicator is located on the right side of the slide, where the extractor is. You will see it protrude slightly when a round is in the chamber.

The trigger safety, firing pin safety, drop safety, and loaded chamber indicator all work together to provide a high level of safety for the shooter. However, as with any firearm, it is still important to handle the Glock 43X carefully and follow safe handling practices to ensure that it is used safely and responsibly.


The Glock 43X sights are configured in a way I see more and more. The first time I saw the configuration was on Kimber’s Stainless II Custom, I didn’t think I would like it, but it has grown on me. It’s a single-dot pattern; the front sight is a dot, but the rear sights are blacked out. In the case of the 43X, the front sight is a bright green night dot that makes target acquisition easy.


Glocks trigger has been a constant for their handguns. They may refine it some, but overall, it’s consistent from one Glock to the next. In addition, it features trigger safety, a standard safety mechanism found in Glock pistols. The trigger safety prevents the trigger from moving unless the shooter applies pressure on the safety tab located within the trigger.

The Glock 43X has a specified trigger pull weight of 5.5 pounds, which is relatively light and easy to manage for most users. However, for our trigger tests, it came in right around 6 pounds consistently. That being said, our gauge comes in heavy with handguns with trigger safety.

The travel before the break on the trigger is more than I care for, but it is something you get used to. If you’re a new shooter and have nothing to compare it to, it won’t ever be an issue for you.

The trigger reset is the distance the trigger must travel forward after firing for the trigger to reset for the next shot. A short trigger reset is desirable for quick follow-up shots and improved accuracy. The Glock 43X trigger reset is relatively short and has a distinct tactile and audible click, making it easy for the shooter to know when the trigger is reset.

Overall, The Glock 43X trigger is well-designed and felt, in the very good range. With a respectable trigger pull weight, trigger safety, and short trigger reset.
