Compact firearms have always occupied an interesting place in firearm design. The challenge is straightforward: reduce overall size and weight without removing too much of the performance, reliability, and practical versatility associated with larger models. Some manufacturers achieve this through carefully shortened designs, while others introduce lighter materials, improved ergonomics, and more efficient mechanical systems. The results range from remarkably capable compact pistols to portable carbines that retain much of their larger counterparts’ character. These 10 firearms demonstrate how thoughtful engineering can make a smaller package surprisingly capable, without relying on size alone to define performance.
1. Glock 19

The Glock 19 demonstrates how a compact pistol can retain much of the practicality associated with a full-sized service handgun. Introduced in 1988, it uses the 9×19mm Parabellum cartridge and features a 4.02-inch barrel, an overall length of 7.36 inches, and a standard 15-round magazine. Its unloaded weight is approximately 23.63 ounces with an empty magazine. The polymer frame helps keep its construction relatively lightweight, while its familiar design and established reputation have made it an influential model in modern handgun development. Rather than dramatically reducing every dimension, Glock created a balanced package that maintains substantial proportions without becoming unnecessarily large.
2. SIG Sauer P365

The SIG Sauer P365 changed expectations surrounding micro-compact pistols when it appeared in 2018. Chambered in 9×19mm, the original model measures just 5.8 inches in overall length and has a 3.1-inch barrel. It weighs approximately 17.8 ounces and features a standard 10-round magazine, with larger magazine options available depending on configuration. Its defining feature is the ability to accommodate a relatively substantial magazine capacity within an unusually small frame. The design combines a polymer grip module with a stainless-steel slide, creating a compact profile without making the pistol feel like an oversized compromise. The P365 subsequently became the foundation for several related models, demonstrating its influence on micro-compact handgun design.
3. Springfield Armory Hellcat

The Springfield Armory Hellcat illustrates how modern engineering has expanded the capabilities of very small defensive pistols. Introduced in 2019, this 9mm micro-compact model features a barrel measuring approximately 3 inches and an overall length of around 6 inches. Its original standard magazine holds 11 rounds, while an extended magazine provides additional capacity. Depending on the configuration, its unloaded weight is approximately 17.9 ounces. Despite its compact dimensions, the Hellcat incorporates a textured polymer grip and a relatively high-capacity magazine arrangement. Its popularity also encouraged further development of the micro-compact category, where manufacturers compete to balance manageable dimensions with useful features. It remains an interesting example of how much functionality can be incorporated into a remarkably small handgun.
4. Glock 26

The Glock 26 takes the familiar Glock design and reduces its dimensions to create a distinctly smaller 9mm handgun. Introduced in 1995, it features a barrel measuring approximately 3.43 inches and an overall length of 6.42 inches. Its standard magazine holds 10 rounds, although compatible larger Glock magazines are available in certain configurations. The pistol weighs approximately 21.7 ounces without a magazine, making it heavier than some newer micro-compacts but still relatively small. Its double-stack magazine arrangement gives the grip a noticeably thicker profile than slim single-stack designs. The Glock 26 is particularly significant because it helped establish the subcompact double-stack pistol as a practical category, combining reduced dimensions with familiar design characteristics.
5. CZ P-10 S

The CZ P-10 S brings the design philosophy of the P-10 family into a smaller striker-fired handgun. Chambered in 9×19mm, this subcompact model features an approximately 3.5-inch barrel and measures around 6.6 inches in overall length. Its standard magazine capacity is 12 rounds, while alternative magazine configurations depend on the market and model. The unloaded weight is approximately 24.4 ounces, reflecting its relatively substantial construction compared with some lightweight micro-compacts. Its polymer frame, textured grip, and familiar control layout give it the appearance of a reduced-size service pistol rather than an entirely different design. The P-10 S demonstrates that compact dimensions do not necessarily require manufacturers to abandon the proportions and handling characteristics associated with larger handguns.
6. Smith & Wesson Model 60

The Smith & Wesson Model 60 offers a different approach to compact firearm design through its traditional five-shot revolver configuration. Introduced in 1965, it became notable as one of the first commercially successful stainless-steel revolvers. Modern versions are available in .38 Special +P, with certain variants also chambered in .357 Magnum. Depending on the version, barrel lengths include 1.875 and 3 inches, while the standard cylinder accommodates five cartridges. Its stainless-steel construction provides durability, although its weight varies with barrel length and configuration. Unlike compact semi-automatic pistols, the Model 60 retains a traditional exposed-hammer revolver layout. Its long production history makes it an important example of how classic mechanical designs can remain relevant in a changing firearms market.
7. Beretta PX4 Storm Compact

The Beretta PX4 Storm Compact demonstrates how a smaller handgun can retain distinctive engineering features from a larger platform. Chambered in 9×19mm, the compact version generally features a 3.2-inch barrel, an overall length of approximately 6.8 inches, and a standard magazine capacity of 15 rounds. Its unloaded weight is around 27 ounces, depending on the particular configuration. One of its most recognizable characteristics is the rotating-barrel operating system, which distinguishes it from many conventional polymer-framed pistols. The design also incorporates a polymer frame and an ergonomic grip intended to provide a comfortable overall shape. By combining relatively substantial magazine capacity with reduced dimensions, the PX4 Storm Compact occupies an interesting position between traditional service pistols and smaller defensive handguns.
8. Ruger PC Carbine

The Ruger PC Carbine shows that compact firearm design is not limited to handguns. This 9mm semi-automatic carbine features a 16.12-inch barrel and an overall length of approximately 34.37 inches in its standard configuration. It has an unloaded weight of around 6.8 pounds and is available with interchangeable magazine-well configurations for compatible Ruger and Glock magazines, depending on the model. Its most recognizable feature is its takedown construction, which allows the barrel and receiver assembly to separate for convenient storage and transportation. The platform combines familiar rifle-style ergonomics with a pistol cartridge, creating a distinctive alternative to conventional full-sized rifles. Its versatility and relatively compact storage arrangement have helped make it an interesting modern addition to the pistol-caliber carbine category.
9. Kel-Tec SUB2000

The Kel-Tec SUB2000 is an unusual pistol-caliber carbine designed around a folding construction. Chambered in 9mm, it uses a 16.25-inch barrel and measures approximately 29.5 inches when unfolded, depending on the generation and configuration. Its unloaded weight is roughly 4.25 pounds, making it considerably lighter than many conventional carbines. A distinctive feature is its ability to fold at the receiver area, reducing its overall storage length substantially. Different versions accept magazines associated with several popular handgun platforms, although compatibility depends on the specific model. Its polymer components and lightweight construction reflect a design philosophy focused on portability. The SUB2000 stands out because it combines a familiar shoulder-fired format with an unconventional folding arrangement, without adopting the dimensions of a traditional full-sized rifle.
10. CZ Scorpion EVO 3 S2 Micro

The CZ Scorpion EVO 3 S2 Micro demonstrates how compact dimensions can be incorporated into a modern pistol-caliber platform. Chambered in 9×19mm, this model features a barrel measuring approximately 5.5 inches and a standard 10-round magazine in the documented configuration. Its overall length varies with the stock arrangement, measuring approximately 15.2 inches in its folded configuration and extending to around 25 inches when fully extended. The unloaded weight is approximately 5.7 pounds with the stock-equipped version. Its construction combines a fiberglass-reinforced polymer receiver with metal components, creating a distinctive appearance. The S2 Micro belongs to the broader Scorpion family, which is known for its compact proportions and modern materials. It illustrates how manufacturers have explored smaller pistol-caliber platforms beyond conventional handgun designs.
