The 5.7 gun has carved a unique niche in the firearms world, sparking debates and garnering a dedicated following. Whether you’re a seasoned firearms enthusiast, a law enforcement professional, or simply curious about this intriguing platform, this comprehensive guide provides an in-depth exploration of the 5.7 gun. We’ll delve into its history, technical specifications, advantages, disadvantages, and real-world applications, offering a balanced and expertly informed perspective. This article aims to be the definitive resource, answering your most pressing questions and providing insights you won’t find anywhere else.

Understanding the 5.7x28mm Cartridge

At the heart of the 5.7 gun lies the 5.7x28mm cartridge. This small-caliber, high-velocity round was originally developed by FN Herstal in the late 1980s as a replacement for the 9mm Parabellum in military and law enforcement applications. The goal was to create a cartridge that offered superior armor penetration, a flatter trajectory, and reduced recoil, all while maintaining a manageable platform size. The 5.7x28mm achieves this through its bottlenecked design and lightweight projectile, typically weighing between 23 and 40 grains.

The cartridge’s design allows it to achieve impressive velocities, often exceeding 2,000 feet per second. This high velocity, combined with the projectile’s pointed shape, contributes to its enhanced armor-piercing capabilities compared to traditional handgun rounds. The reduced recoil makes the 5.7 gun easier to control, especially in rapid-fire scenarios, potentially leading to improved accuracy and faster follow-up shots.

The 5.7x28mm isn’t without its detractors. Some argue that its small size compromises its terminal ballistics, meaning its ability to effectively incapacitate a target. Others criticize its higher cost compared to more common cartridges like the 9mm. However, proponents maintain that its advantages in specific situations outweigh these drawbacks.

The FN Five-seveN: A Flagship Firearm

The FN Five-seveN pistol is arguably the most well-known firearm chambered in 5.7x28mm.

The Advantages of the 5.7 Gun System

The 5.7 gun system, encompassing both the cartridge and the firearms chambered for it, offers several distinct advantages:

Armor Penetration: The 5.7x28mm cartridge is known for its ability to penetrate soft body armor, a crucial advantage for law enforcement and military personnel facing adversaries equipped with such protection.
Flat Trajectory: The high velocity of the 5.7x28mm cartridge results in a flatter trajectory compared to slower handgun rounds. This makes it easier to accurately engage targets at longer distances.
Reduced Recoil: The relatively low recoil of the 5.7x28mm cartridge makes the 5.7 gun easier to control, especially in rapid-fire scenarios. This can lead to improved accuracy and faster follow-up shots. Users consistently report increased confidence and control when transitioning from larger caliber handguns.
High Capacity: Firearms chambered in 5.7x28mm typically feature high-capacity magazines, providing a significant advantage in situations where a high volume of fire is required.
Lightweight Ammunition: The 5.7x28mm cartridge is relatively lightweight compared to other handgun rounds, allowing users to carry more ammunition without significantly increasing their load.

These advantages translate to real-world value in various scenarios. Law enforcement officers can benefit from the increased armor penetration and higher capacity, while sport shooters can appreciate the flatter trajectory and reduced recoil. The compact size and lightweight nature of the 5.7 gun also make it a viable option for concealed carry for those who prioritize these factors.
