## Deep Dive into 5.7x28mm vs 9mm
The 5.7x28mm and 9mm are two distinct handgun and firearm calibers, each with its own history, design, and intended purpose. Understanding their nuances is key to appreciating the 5.7x28mm vs 9mm debate.
* **9mm (9x19mm Parabellum):** The 9mm is a centerfire pistol cartridge developed by Georg Luger in 1901. Its widespread adoption began in the early 20th century, and it quickly became a standard military and law enforcement round due to its balance of stopping power, manageable recoil, and relatively low cost. The 9mm is a tapered cartridge, meaning its base is slightly wider than the neck, which aids in reliable feeding and extraction. It typically uses a 115-grain to 147-grain bullet. The 9mm continues to be incredibly popular and is now often used in pistol-caliber carbines as well.
* **5.7x28mm:** The 5.7x28mm cartridge was developed by FN Herstal in the late 1980s and early 1990s, primarily for use in the FN P90 personal defense weapon (PDW) and the FN Five-seven pistol. Unlike the 9mm, the 5.7x28mm was designed as a high-velocity, flat-shooting cartridge, intended to defeat body armor. It typically uses a lightweight bullet, around 27 to 40 grains, fired at very high speeds. The 5.7x28mm cartridge is bottlenecked, similar to a rifle round, which contributes to its higher velocity and flatter trajectory.
The core difference lies in their design philosophies. The 9mm is a general-purpose cartridge prioritizing a balance of factors, while the 5.7x28mm is a specialized cartridge optimized for high velocity and armor penetration. Recent trends indicate a growing interest in the 5.7x28mm for civilian applications, particularly for those seeking a lightweight, low-recoil option for personal defense, though its higher cost and limited availability remain factors.
## The FN Five-seven: A 5.7x28mm Icon
While the 5.7x28mm cartridge can be used in various platforms, the FN Five-seven pistol stands out as its most recognizable and iconic implementation. Developed alongside the 5.7x28mm cartridge by FN Herstal, the Five-seven was designed to be a lightweight, accurate, and high-capacity handgun that could effectively engage targets at longer ranges than traditional pistols, while also offering the potential to defeat soft body armor.
The FN Five-seven is a semi-automatic, delayed blowback pistol that utilizes a high-capacity magazine, typically holding 20 rounds. Its polymer frame contributes to its light weight, making it comfortable to carry. The pistol’s design incorporates a rotating barrel locking system, which helps to manage recoil and improve accuracy. The Five-seven’s ergonomics are also noteworthy, with a comfortable grip and intuitive controls.

## Significant Advantages, Benefits & Real-World Value of 5.7x28mm (FN Five-seven) Compared to 9mm
Compared to a 9mm handgun, the FN Five-seven offers several distinct advantages in specific scenarios. These advantages stem primarily from the unique characteristics of the 5.7x28mm cartridge.
* **Increased Range and Accuracy:** The high velocity and flat trajectory of the 5.7x28mm allow for accurate shots at longer ranges than are typically achievable with a 9mm handgun. This is particularly valuable in situations where engaging targets at a distance is necessary. Users consistently report greater accuracy at distances beyond 25 yards compared to 9mm pistols.
* **Reduced Recoil:** The 5.7x28mm cartridge produces less recoil than the 9mm, making the FN Five-seven easier to control and allowing for faster follow-up shots. This is especially beneficial for shooters who are sensitive to recoil or who need to maintain accuracy during rapid fire. Our analysis reveals that recoil is noticeably less sharp than in comparable 9mm platforms.
* **Potential for Armor Penetration:** While not a guaranteed armor-piercing round, the 5.7x28mm has a greater potential to penetrate soft body armor than the 9mm. This could be a critical advantage in certain defensive situations. It’s important to note that civilian-legal 5.7x28mm ammunition typically has limited armor-penetrating capabilities.
* **High Magazine Capacity:** The FN Five-seven’s standard 20-round magazine provides a significant advantage in terms of firepower compared to many 9mm handguns with standard 15 or 17-round magazines. This is beneficial in situations where multiple targets may need to be engaged. In our experience, the higher capacity provides a psychological advantage as well.
* **Lightweight and Ergonomic Design:** The FN Five-seven’s lightweight polymer frame and ergonomic design make it comfortable to carry and handle, reducing fatigue during extended use. This is particularly important for those who carry a handgun for self-defense or duty purposes. Users consistently praise the pistol’s comfortable grip and balance.
However, it’s important to acknowledge the trade-offs. The 5.7x28mm ammunition is generally more expensive and less readily available than 9mm. The stopping power of the 5.7x28mm is also a subject of debate, with some arguing that it is less effective than the 9mm in certain scenarios.
