The 5.7x28mm cartridge, a relatively small but potent round, has carved a niche for itself in the world of firearms. Developed by Fabrique Nationale (FN) Herstal, this round isn't your typical handgun or rifle cartridge; it occupies a unique space between pistol and submachine gun calibers, offering a compelling blend of features and capabilities. This article will explore the guns that fire this intriguing ammunition, examining their design, applications, and overall impact.
Understanding the 5.7x28mm Cartridge
Before diving into specific firearms, let's understand what makes the 5.7x28mm unique. This high-velocity cartridge is designed for maximum penetration and stopping power at relatively close ranges. Its smaller size allows for higher magazine capacities compared to larger calibers, making it ideal for personal defense and close-quarters combat scenarios. The bullet's lightweight nature also contributes to its flat trajectory, reducing the need for significant adjustments at short to medium ranges. However, its smaller size means it loses velocity more quickly over distance than larger cartridges.
Popular Firearms Chambered in 5.7x28mm
Several firearms have been chambered for this specialized cartridge, each with its own strengths and weaknesses. Let's examine some of the most notable:
1. FN Five-seveN Pistol
Arguably the most iconic firearm chambering the 5.7x28mm, the FN Five-seveN pistol is known for its high-capacity magazines (typically 20 rounds), sleek design, and impressive accuracy. Its relatively lightweight design, while contributing to comfort, can also impact recoil management for some shooters. The FN Five-seveN's primary application is personal defense and law enforcement, although its use extends to various civilian contexts as well.
2. FN P90 Personal Defense Weapon (PDW)
Moving beyond pistols, the FN P90 is a bullpup-style personal defense weapon that also utilizes the 5.7x28mm cartridge. This design offers a compact profile despite its longer barrel, making it well-suited for close-quarters combat situations. Its high-capacity magazine (50 rounds) and impressive rate of fire make it a formidable weapon in the right hands. Used by military and law enforcement units globally, the FN P90 is a testament to the 5.7x28mm's versatility in different firearm platforms.
3. PS90 Carbine
The PS90 is a semi-automatic carbine version of the P90, designed primarily for civilian markets. It retains the unique bullpup design and high-capacity magazines, offering a higher level of accuracy and range compared to the P90's fully automatic capabilities. This makes it a popular choice amongst enthusiasts who value accuracy and a high round count.
Considerations for Choosing a 5.7x28mm Firearm
The decision to acquire a 5.7x28mm firearm should be based on careful consideration of several factors:
- Intended Use: Are you looking for personal defense, competition shooting, or collecting? The purpose significantly influences the best choice.
- Ergonomics and Handling: Different firearms will handle differently. Consider factors such as size, weight, and recoil.
- Ammunition Availability and Cost: The availability and price of 5.7x28mm ammunition should be factored into your decision.
- Legal Restrictions: Always check and comply with all local, state, and federal regulations regarding firearms ownership and use.
Conclusion
The 5.7x28mm cartridge and the firearms that chamber it represent a fascinating segment of the firearms world.
