The Complete Overview of Glock Subcompact Pistols
Glock’s subcompact lineup has long been a favorite for concealed carry enthusiasts, but the Glock 42 vs Glock 43 size comparison cuts to the heart of their distinct roles. The 42, chambered in .22 LR, is the smallest Glock ever produced, weighing just 14.6 ounces unloaded. Its diminutive size makes it a favorite for range practice or light carry, though its low-energy rounds limit its self-defense utility. The 43, in contrast, fires .380 ACP—a caliber that balances concealability with meaningful stopping power. At 17.6 ounces, it’s heavier but far more capable in real-world scenarios.
The Glock 42 vs Glock 43 size debate isn’t just about measurements—it’s about the practical implications of those measurements. The 42’s 0.7-inch narrower grip and 0.1-inch shallower frame mean it slips into a pocket or ankle holster with ease, but its recoil is negligible, making it more of a training tool than a defensive firearm. The 43’s slightly larger dimensions translate to better recoil control and a more substantial trigger pull, though it still struggles to match the ergonomics of full-size pistols.
Historical Background and Evolution
Glock introduced the 42 in 2014 as a response to the growing demand for ultra-compact firearms, particularly in law enforcement training and civilian practice. Its .22 LR chambering was a nod to the Glock 25’s legacy but scaled down for minimalism. The 43 followed in 2015, filling a gap between the 42 and larger Glock models by offering .380 ACP’s balance of concealability and stopping power. Both pistols inherited Glock’s signature polymer frame and internal safety mechanisms, ensuring reliability without the need for manual safeties.
The Glock 42 vs Glock 43 size evolution reflects Glock’s broader strategy of modularity. While the 42 was designed for simplicity and affordability, the 43 aimed to provide a more serious self-defense option without sacrificing concealability. The 43’s slightly larger dimensions allowed for a more robust grip and a longer sight radius, addressing common complaints about the 42’s limited practicality. This incremental scaling became a hallmark of Glock’s approach to subcompact pistols.
Core Mechanisms: How It Works
Both pistols operate on Glock’s signature short-recoil system, where the barrel and slide lock back briefly before unlocking and cycling the action. The Glock 42’s mechanism is optimized for the low recoil of .22 LR, with a lighter trigger pull (typically 6–8 pounds) and a shorter reset distance. The Glock 43, firing .380 ACP, has a slightly heavier trigger (around 8–10 pounds) and a more pronounced reset due to the higher recoil energy. Despite these differences, both pistols maintain Glock’s reputation for simplicity and durability.
The Glock 42 vs Glock 43 size also affects their internal components. The 42’s slide is shallower, allowing for a more compact design, while the 43’s slide accommodates the longer .380 ACP cartridge. The 43’s grip frame is wider to improve recoil control, a critical adaptation for a caliber that can still deliver meaningful recoil despite its small size. Both pistols lack external safeties, relying instead on Glock’s internal drop safety—a design choice that prioritizes speed over additional controls.
Key Benefits and Crucial Impact
The Glock 42’s primary advantage is its unmatched concealability. Its slim profile and light weight make it ideal for discreet carry, particularly for those with smaller hands or limited storage space. However, its .22 LR rounds lack the energy to reliably stop an assailant, making it more of a range tool or backup firearm. The Glock 43, while slightly larger, offers a practical compromise with .380 ACP’s balance of concealability and stopping power. Its slightly heavier recoil is manageable, and its longer sight radius improves accuracy at distance.
The Glock 42 vs Glock 43 size debate often hinges on intended use. The 42 excels in training scenarios, where its low recoil and minimal weight reduce fatigue during extended practice. The 43, meanwhile, is better suited for everyday carry (EDC) or as a secondary firearm, where its .380 ACP rounds provide a more realistic self-defense option. Both pistols benefit from Glock’s reputation for reliability, but their real-world impact differs significantly based on the shooter’s needs.
"The Glock 42 is a toy, but a useful one. The 43 is a real gun—just a small one." — Industry firearms instructor, 2023
Major Advantages
- Concealability: The Glock 42’s extreme compactness makes it the easiest to hide, while the 43 offers a slightly more substantial grip without sacrificing too much concealability.
- Stopping Power: The Glock 43’s .380 ACP rounds provide far more energy than the 42’s .22 LR, making it a better choice for self-defense.
- Trigger Discipline: The 42’s lighter trigger pull is ideal for quick follow-up shots in training, while the 43’s slightly heavier pull improves accuracy in defensive scenarios.
- Recoil Management: The 43’s wider grip and longer sight radius make it easier to control recoil, a critical factor for shooters with less experience.
- Ammunition Availability: The 43 benefits from a wider variety of .380 ACP loads, including hollow points and +P options, whereas the 42 is limited to .22 LR’s softer rounds.

Comprehensive FAQs
Q: Which pistol is better for concealed carry—the Glock 42 or the Glock 43?
The Glock 42 is easier to conceal due to its smaller size, but the Glock 43’s slightly larger dimensions provide a more substantial grip and better recoil control. If stopping power is a priority, the 43 wins. For pure concealability, the 42 is unmatched.
Q: Can the Glock 42 be used for self-defense?
Technically yes, but its .22 LR rounds lack the energy to reliably stop an assailant. It’s better suited for range practice or as a backup firearm rather than primary self-defense.
Q: How does the trigger pull differ between the two?
The Glock 42 has a lighter trigger pull (6–8 lbs), ideal for quick follow-up shots. The Glock 43’s trigger is slightly heavier (8–10 lbs) to manage the higher recoil of .380 ACP.
Q: Are there aftermarket upgrades available for either pistol?
Yes. Both models support extended magazines, textured grips, and sights. The Glock 43 also benefits from a wider variety of .380 ACP loads, including hollow points and +P options.
Q: Which pistol is more reliable?
Both are known for Glock’s reliability, but the Glock 43’s slightly higher recoil energy means it may require more frequent maintenance. The 42’s low recoil makes it slightly more forgiving in terms of wear and tear.
Q: Can I use the same holster for both pistols?
Some holsters are designed to fit both, but the Glock 42’s narrower grip may require a more specialized holster for optimal retention. The 43’s standard subcompact dimensions make it compatible with most .380 ACP holsters.
Q: What’s the best use case for each pistol?
The Glock 42 excels as a training tool or secondary firearm due to its low recoil and compact size. The Glock 43 is better for everyday carry or as a primary self-defense pistol thanks to its .380 ACP chambering and improved ergonomics.
