The 5.7x28mm cartridge, known for its high velocity and unique capabilities, isn't found in your average hunting rifle or shotgun. Its niche applications mean a limited, but fascinating, range of firearms utilize this round. This guide will explore the most prominent weapons chambered in 5.7x28mm, delving into their features and intended uses.
The FN Five-seveN Pistol: The Defining Weapon
The FN Five-seveN pistol is arguably the most recognizable firearm chambering the 5.7x28mm round. Developed by Fabrique Nationale (FN) Herstal, this pistol is renowned for its high capacity magazines, often holding 20 rounds or more. Its compact size and manageable recoil make it suitable for personal defense and law enforcement applications. The Five-seveN is favored for its ability to penetrate body armor, a crucial factor in its design philosophy. Key features include:
- High-capacity magazines: Offering superior firepower compared to many other handguns.
- Lightweight design: Enhancing maneuverability and reducing fatigue during extended use.
- Low recoil: Contributing to improved accuracy and faster follow-up shots.
- Penetration capabilities: A key design feature, particularly effective against soft body armor.
The FN P90 Personal Defense Weapon (PDW): A Unique Submachine Gun
The FN P90 stands out as a unique submachine gun specifically designed around the 5.7x28mm cartridge. Its bullpup configuration, meaning the magazine is housed behind the trigger group, allows for a surprisingly compact weapon despite its considerable firepower. The P90 is often favored by military and law enforcement units for its close-quarters combat capabilities. Key features of the P90 include:
- Bullpup design: Maximizes barrel length while maintaining a compact overall size.
- High-capacity magazine: Similar to the Five-seveN, offering superior firepower in close-quarters combat.
- Ergonomic design: Specifically designed for ease of use and rapid target acquisition.
- Low recoil and manageable weight: Contributing to enhanced accuracy and control during rapid fire.
Other Less Common Firearms
While the FN Five-seveN and P90 dominate the 5.7x28mm landscape, other less commonly known firearms have also been chambered in this caliber. These are often limited production runs, custom builds, or modifications for specific niche uses. Researching these requires delving into specialized firearms forums and collector communities. It's important to note that the availability and legality of these weapons vary significantly depending on location and applicable laws.
Understanding the 5.7x28mm Cartridge
The 5.7x28mm cartridge's distinctive features explain its choice in specialized firearms. Its high velocity contributes to its flat trajectory and impressive penetration capabilities, especially against lighter forms of body armor. However, it's crucial to understand its limitations. While effective at close to medium ranges, its relatively small size and light weight can lead to reduced stopping power at longer distances compared to larger calibers.
Conclusion
The 5.7x28mm round, while not ubiquitous, holds a significant place in the world of firearms. The FN Five-seveN and P90 remain the defining weapons showcasing its capabilities, particularly in personal defense and specialized military/law enforcement roles.
