Glock pistols are known for their reliability, simplicity, and durability—qualities that make them a top choice for law enforcement, civilians, and concealed carriers worldwide. With so many models on the market, one of the most common questions people ask is: “What is the smallest Glock available?” This guide breaks down the smallest Glock, why it’s so compact, how it compares to the smallest 9mm option, and what to consider when choosing an ultra-concealable handgun.

The Smallest Glock Ever Made

The Glock 42 is officially recognized as the smallest Glock pistol. Chambered in .380 Auto, it is specifically engineered for deep concealment, offering a slim, lightweight build that makes it incredibly easy to carry discreetly. Its small profile and soft recoil make it especially popular among those who need a compact defensive option without sacrificing the well-known Glock reliability.

Why the Glock 42 Holds the “Smallest Glock” Title

Glock designed the G42 to be as small as possible while maintaining consistent performance. Features that make it the smallest Glock include:

• A short overall length ideal for pocket carry or compact holsters
• A narrow, single-stack frame that reduces printing under clothing
• A lightweight polymer build for comfortable all-day carry
• Reduced recoil thanks to the .380 Auto cartridge

These combined features set the G42 apart as the most compact model Glock has ever produced.

The Smallest 9mm Glock

If you prefer the versatility and performance of a 9mm, the smallest Glock in this caliber is the Glock 43. Like the G42, the G43 uses a slim single-stack design but is slightly larger to support the 9mm round. It’s still highly concealable, making it a top choice for everyday carry.

Many shooters consider the G43 the perfect balance between compact size and 9mm performance—offering a small footprint without sacrificing effectiveness.

Comparing the G42 and G43

While both pistols are designed for concealment, their differences come down to caliber, recoil, and size. The G42 is smaller and easier to shoot for those sensitive to recoil, while the G43 offers the stopping power and magazine options of 9mm. Both models carry Glock’s signature reliability and simplicity, making either a solid choice depending on your preferences.

Who Should Choose the Smallest Glock?

The Glock 42 is ideal for:

• Deep concealment carry (pocket, ankle, minimalist IWB holsters)
• Users with smaller hands
• Those who prefer lighter recoil
• Situations where discretion is absolutely essential

Meanwhile, shooters who want a compact yet powerful 9mm option may gravitate toward the G43 or the slightly expanded G43X, which offers a fuller grip while still remaining slim and carry-friendly.

How to Choose the Right Compact Glock

When selecting a compact or subcompact Glock, consider factors like hand size, recoil tolerance, holster compatibility, and preferred ammunition. It’s always best to handle and test-fire different models if possible. Glock’s official website, along with authorized dealers, provides detailed specifications and helpful comparisons to guide your decision.

So, what is the smallest Glock? The answer is clear: the Glock 42 stands as Glock’s smallest pistol ever produced. If you’re looking for a minimal, ultra-concealable firearm that still carries Glock’s trusted performance, the G42 remains unmatched. But if you want the smallest Glock in 9mm, the Glock 43 is the leading choice.

No matter which model you choose, proper training, safe handling, and compliance with local firearm laws are essential for responsible ownership.
