Difference Between Glock 43 and 43X: Key Features Compared

What’s the difference between the Glock 43 and Glock 43X? The Glock 43 is slimmer and easier to conceal, while the 43X offers a longer grip and higher capacity—10 rounds versus 6—without adding much bulk.

Both pistols maintain Glock’s reliability and minimalist design. The 43 is ideal if deep concealment is your top priority. The 43X suits those who prefer more control and rounds on tap. If your daily carry depends on comfort, discretion, and fast access, your choice comes down to what you’re willing to trade: size or capacity. Either way, both are practical, proven, and ready to carry.

Similarities Between Glock 43 and 43X

Both the Glock 43 and 43X share Glock’s slimline 9mm philosophy: striker-fired operation with the Safe Action system, low-maintenance reliability, and a narrow, concealment-first footprint. That common design gives both pistols predictable trigger feel, similar recoil behavior for 9mm, and easy, intuitive pointing.

They also behave the same under the user’s hands — identical manual of arms, takedown, and basic manipulation — so draw, reload, and malfunction drills you practice on one transfer directly to the other. Both are built to prioritize deep concealment without sacrificing everyday shootability.

Finally, they occupy the same role in a carry kit: minimal profile, comfortable daily carry, and straightforward servicing. If you master one, you’ll find the other feels instantly familiar.

Quick Verdict — Which Glock is Better for You?

Choosing between the Glock 43 and Glock 43X depends on your priorities in concealed carry, shooting comfort, and magazine capacity. Both models excel in reliability and simplicity but cater to different user needs.

• Glock 43: If deep concealment is your primary concern, the Glock 43 offers an ultra-slim profile with a width of just 1.06 inches. With a standard six-round magazine, it's well-suited for civilian concealed carriers prioritizing minimal printing over extended firepower. This model works best for those with smaller hands or who prefer lightweight firearms during long periods of carry.
• Glock 43X: For users seeking enhanced grip control and higher round count without sacrificing too much concealability, the Glock 43X stands out. Its slightly longer grip accommodates a ten-round magazine while maintaining a slim frame at 1.10 inches wide. The increased surface area improves handling during rapid-fire drills or defensive scenarios under stress.

Consider your daily routine, clothing preferences, and training habits before deciding. The Glock 43 suits minimalist setups where absolute concealment is critical, while the Glock 43X provides better performance for range practice or high-stress environments requiring additional rounds on hand.

Key Specs Breakdown

Design & Ergonomics

The Glock 43 and Glock 43X share a compact design, but their ergonomics cater to different needs. The Glock 43 features an ultra-slim frame with a width of 1.06 inches, making it ideal for deep concealment in IWB or appendix carry holsters. Its shorter grip reduces printing under light clothing, appealing to those prioritizing discretion.

In contrast, the Glock 43X incorporates a slightly wider frame at 1.10 inches and an extended grip length. This design improves handling for shooters with larger hands or those seeking better control during rapid fire.

Caliber & Barrel Length

Both pistols are chambered in 9x19mm (9mm Luger), offering manageable recoil and compatibility with widely available ammunition types. Their shared caliber ensures consistent performance across defensive scenarios and practice sessions.

The barrel lengths differ slightly: the Glock 43 has a 3.41-inch barrel, while the Glock 43X measures at 3.39 inches. This minor variation doesn’t significantly impact accuracy or muzzle velocity but may influence your choice if you prioritize specific aftermarket barrel options for threaded suppressors or compensators.

Capacity &Magazine Options

Magazine capacity is one of the most significant differences between these models. The Glock 43 includes a standard six-round magazine, which keeps its profile slim and lightweight—ideal for concealed carriers who value minimal bulk.

The Glock 43X offers a ten-round magazine as standard, providing increased firepower without requiring extended baseplates or aftermarket solutions. For competitive shooters or law enforcement professionals needing higher capacities, third-party manufacturers like Shield Arms produce flush-fit magazines that expand capacity to up to fifteen rounds for the Glock 43X.

Trigger Performance &Safety Features

Both pistols feature Glock’s Safe Action System with three integrated safeties: trigger safety, firing pin safety, and drop safety. These mechanisms ensure reliable operation while preventing accidental discharges during routine handling or high-stress situations.

Trigger pull weights are similar across both models at approximately 5.5 pounds out of the box; but, some users report smoother break-in periods on the Glock 43X due to its newer-generation components. Aftermarket upgrades such as flat-faced triggers can enhance precision shooting further if factory settings don’t meet your preferences during dry-fire drills or live-fire exercises.

Shooting Performance in the Field

Accuracy &Grouping

The Glock 43 and Glock 43X both deliver consistent accuracy, but their designs cater to different shooting styles. The Glock 43, with its shorter grip and barrel (3.41 inches), is optimized for close-range engagements typical of concealed carry scenarios. At distances up to 15 yards, you can expect tight groupings if you maintain proper trigger control and sight alignment. But, the smaller grip may challenge shooters with larger hands during extended sessions.

The Glock 43X offers a longer grip and slightly improved sight radius due to its identical barrel length but taller frame. This design enhances stability, allowing more precise shot placement at mid-range distances of 20-25 yards.

Competitive shooters or law enforcement officers training for rapid target acquisition often favor this model for its balance between compactness and controllability. Both models perform well with aftermarket sights like Trijicon HD XR or AmeriGlo Bold for enhanced visibility.

Reliability &Durability

Both pistols uphold Glock's reputation for reliability under various conditions. The Glock 43’s slim profile makes it less prone to snagging debris when carried inside-the-waistband (IWB) or appendix holsters, such as those from Alien Gear Holsters made of Boltaron material. It cycles reliably even after exposure to dirt or moisture during everyday carry routines.

The Glock 43X shares the same robust polymer frame and Tenifer-coated slide finish as the Glock 43, ensuring resistance against corrosion and wear over time. Its ten-round magazine provides additional capacity without compromising feeding reliability, making it suitable for high-stress environments like tactical drills or defensive scenarios.

Whether you're conducting range practice or relying on these firearms in extreme weather conditions, both models demonstrate exceptional durability across thousands of rounds fired.

Recoil and Handling for Different Use Cases

Recoil management differs significantly between these two models due to their size variations. The Glock 43’s lighter weight (17.99 ounces unloaded) results in sharper felt recoil compared to the heavier Glock 43X (18.7 ounces unloaded). For new gun owners practicing controlled pairs or double taps, the reduced surface area on the Glock 43’s grip might require adjustments in hand positioning after each shot.

In contrast, the extended grip of the Glock 43X allows better leverage during rapid-fire sequences common in competitive shooting or defensive drills involving multiple targets. Law enforcement professionals often prefer this feature when transitioning between one-handed firing stances under stress.

Concealed Carry &Practical Use

Comfort for Daily Carry

The Glock 43 and Glock 43X cater to different preferences in concealed carry comfort. The Glock 43, with its slim width of 1.06 inches and lightweight frame at approximately 17.99 ounces unloaded, is ideal for deep concealment. Its compact size minimizes printing under fitted clothing, making it suitable for appendix or inside-the-waistband (IWB) holsters. This model works well if you prioritize discretion during daily activities.

In contrast, the Glock 43X offers a slightly larger grip and a width of 1.10 inches but maintains excellent concealability due to its short slide length. Weighing about 18.7 ounces unloaded, it balances added capacity with manageable weight.

The extended grip improves ergonomics for users with medium-to-large hands while still fitting comfortably in IWB or appendix holsters like those made by Alien Gear Holsters from Boltaron material. Choose the Glock 43X if you value enhanced control without sacrificing too much portability.

Draw Speed &Accessibility

Both models provide quick access when paired with appropriate holster setups, though their designs influence draw dynamics differently. The Glock 43's smaller grip reduces snag risks during rapid draws from tight-fitting holsters like IWB options or pocket configurations, which are popular among civilian carriers prioritizing speed in confined spaces.

The Glock 43X’s longer grip aids in achieving a more secure purchase during the draw sequence, especially under stress or while wearing gloves—a feature appreciated by law enforcement officers and competitive shooters alike. But, this increased surface area may require slight adjustments when drawing from high-retention holsters such as OWB rigs designed for active environments.

Selecting between these pistols depends on your training habits and scenarios; the Glock 43 excels in ultra-concealable setups requiring minimal movement, while the Glock 43X supports faster follow-up shots due to improved handling post-draw.

Holster Recommendations

Selecting the right holster for your Glock 43 or 43X ensures secure retention, accessibility, and comfort during concealed carry. Both models accommodate various holster styles depending on your carry position and daily activities.

• OWB (Outside-the-Waistband): OWB holsters provide easy access and are ideal for range use or open carry scenarios. For the Glock 43X's larger grip profile, consider a high-retention option to ensure stability during movement.
• IWB (Inside-the-Waistband): IWB holsters excel in concealment by tucking the firearm close to your body. The slim frame of the Glock 43 fits comfortably under tighter clothing without printing. Adjustable cant options enhance draw speed for both pistols.
• Appendix Carry: Appendix rigs work well with the compact dimensions of either model. Minimalistic designs reduce bulk while maintaining quick access. A single-clip design suits the Glock 43’s lightweight build, while dual clips improve balance for the heavier Glock 43X.
• Chest Rigs: Chest rigs cater to outdoor enthusiasts or law enforcement professionals needing hands-free convenience. These setups fit securely over gear and allow rapid deployment in active environments.
