Design and Construction

Slim, Single-Stack Frame

The Glock 43X utilizes a slim, single-stack magazine design that keeps the grip narrow—about 1.1 inches wide—making it ideal for shooters seeking a pistol that’s easy to conceal and comfortable to hold. The longer grip length compared to the original Glock 43 allows for a full four-finger grip for many shooters, which improves control and handling.

Compact Slide and Barrel

The pistol features a 3.41-inch barrel paired with a slide that keeps the overall length compact at 6.50 inches. This compact size makes the Glock 43X comfortable for daily carry while maintaining enough barrel length for respectable accuracy and velocity.

Glock Marksman Barrel

Equipped with Glock’s renowned Marksman Barrel, the Glock 43X features polygonal rifling that enhances accuracy, velocity, and barrel life compared to traditional rifling.

Ergonomics and Controls

The Glock 43X is built on the Gen 5 frame platform and includes the following ergonomic features:

• Ambidextrous slide stop levers for left- or right-handed shooters.
• Flared magwell to assist rapid reloads.
• Removal of finger grooves for a universal, comfortable grip.
• Textured grip for secure handling in all conditions.

Durable Slide Finish

The slide features Glock’s nDLC finish, a nitride-based coating that provides exceptional corrosion resistance, scratch resistance, and long-term durability.

Performance and Shooting Experience

Accuracy

With its Marksman Barrel and adequate sight radius for its size, the Glock 43X delivers accurate shooting at typical defensive ranges. The compact 3.41-inch barrel offers a solid balance between concealability and ballistic performance.

Trigger

The Gen 5 Safe Action® trigger system features a smooth, consistent pull of approximately 5.5 pounds with a tactile reset, providing enhanced control and faster follow-up shots.

Recoil and Control

The polymer frame’s ergonomics combined with the single-stack design contribute to manageable recoil and quick target reacquisition. This makes the Glock 43X suitable for shooters of various skill levels.

Reliability

Glock pistols are famous for their near-indestructible reliability, and the Glock 43X lives up to this legacy, performing flawlessly with a wide range of ammunition and under adverse conditions.

Magazine Capacity and Ammunition

One of the key selling points of the Glock 43X is its 10-round single-stack magazine, doubling the capacity of the original Glock 43’s six rounds while maintaining a slim grip profile. The magazines are interchangeable with other Glock Slimline models, making upgrades or replacements easy.

Ideal Applications

Concealed Carry and Everyday Carry

The Glock 43X’s slim, lightweight design combined with a robust 10-round capacity makes it an excellent choice for daily concealed carry. It’s comfortable enough for all-day wear and discreet enough to avoid printing under clothing.

Personal Defense

The reliable Glock 43X offers the firepower and performance necessary for self-defense scenarios, with quick handling and effective stopping power in 9mm.

Backup or Off-Duty Carry

Law enforcement officers often select the Glock 43X as a backup or off-duty carry weapon due to its concealability and Glock reliability.

Range Training and Practice

With its manageable recoil, ergonomic design, and accuracy, the Glock 43X is also a great choice for regular range use and shooting practice.

Customization and Accessories

While the Glock 43X comes stock with excellent features, it also supports a range of aftermarket customization options:

Sights

Upgrading to night sights, fiber optic sights, or Tritium options is popular for improved target acquisition in low-light conditions.

Triggers

Aftermarket trigger upgrades can provide a lighter pull, crisper break, or shorter reset to improve shooting performance.

Holsters

A variety of holster options are available, including inside-the-waistband (IWB), outside-the-waistband (OWB), pocket, and appendix carry holsters specifically designed for the slim profile.

Magazines

Extended magazines and base plates are available to increase capacity or improve grip length for shooters with larger hands.

Optics-Ready Slides

Though the standard Glock 43X does not come optics-ready, aftermarket modifications and slide milling services can accommodate red dot sights.

Maintenance and Care

Routine maintenance is key to keeping the Glock 43X performing reliably:

• Regular Cleaning: Clean the barrel, slide, and frame after each use to prevent buildup.
• Lubrication: Apply proper lubrication to slide rails and moving parts as per Glock’s recommendations.
