The 5.7x28mm cartridge is a unique and often misunderstood round, known for its high velocity, flat trajectory, and impressive penetration capabilities. This article will delve into the world of firearms chambered in 5.7x28mm, focusing on their characteristics, applications, and potential drawbacks. We'll explore the most prominent firearm in this caliber, the FN Five-seveN pistol, along with other less common weapons.
The FN Five-seveN: The Defining 5.7mm Pistol
The FN Five-seveN pistol, manufactured by Fabrique Nationale de Herstal (FN), is arguably the most recognizable firearm chambered in 5.7x28mm. Its sleek design, high capacity magazines, and unique cartridge have made it a popular choice for both law enforcement and civilian markets, albeit one often surrounded by controversy.
Key Features of the FN Five-seveN:
- High Velocity: The 5.7x28mm cartridge boasts a significantly higher muzzle velocity compared to many other pistol calibers, leading to a flatter trajectory and increased effective range.
- Penetration: The small, lightweight projectile offers impressive penetration through soft barriers, such as clothing and light body armor. This is a significant factor in its appeal for law enforcement and military applications.
- High Capacity Magazines: The Five-seveN typically utilizes high-capacity magazines, enabling users to carry a significant amount of ammunition.
- Ergonomics: The pistol's design often receives praise for its comfortable grip and ease of handling.
Potential Drawbacks of the FN Five-seveN:
- Stopping Power: While penetration is high, the relatively small projectile of the 5.7x28mm cartridge raises questions regarding its stopping power against larger targets. This remains a subject of ongoing debate.
- Cost: Ammunition for the Five-seveN can be more expensive compared to more common pistol calibers.
- Recoil Sensitivity: The high-velocity round can lead to more felt recoil than some shooters might prefer, particularly for those less experienced with firearms.
Beyond the Five-seveN: Other 5.7x28mm Firearms
While the FN Five-seveN dominates the 5.7x28mm market, a few other firearms exist chambered in this caliber, though they are less prevalent. These typically include select-fire submachine guns and personal defense weapons (PDWs). Information on these less common firearms can often be found through specialized firearms forums and publications.
