The 5.7x28mm cartridge, known for its high velocity and small size, has carved a niche for itself in the world of firearms. While not as ubiquitous as 9mm or .45 ACP, pistols chambered in 5.7x28mm offer unique advantages, particularly in personal defense and specialized applications. This guide delves into the world of pistols that shoot 5.7x28mm, exploring their features, uses, and considerations. We'll cover the key characteristics of the round and why you might choose a 5.7x28mm pistol over other options.
Understanding the 5.7x28mm Cartridge
The 5.7x28mm cartridge, developed by FN Herstal, isn't your typical handgun round. Its small size belies its impressive capabilities. Key characteristics include:
- High Velocity: The 5.7x28mm boasts significantly higher velocity than most common pistol calibers, resulting in flatter trajectories and less bullet drop at longer ranges.
- Small Caliber: The small bullet diameter contributes to higher magazine capacity compared to larger calibers.
- Penetration: While capable of penetrating soft targets effectively, the 5.7x28mm's penetration against hard barriers like car doors or body armor is debated and often depends on the specific bullet design. Some bullets are designed for improved penetration, while others prioritize expansion and wounding capability.
- Low Recoil: Its lighter weight and high velocity contribute to relatively low recoil, enhancing controllability and faster follow-up shots.
Popular Pistols Chambered in 5.7x28mm
Several manufacturers produce pistols chambered in 5.7x28mm, each with its own set of features and target market. Here are some of the most well-known examples:
FN Five-seveN
The FN Five-seveN is arguably the most recognizable pistol in this caliber. Designed by FN Herstal, it's known for its:
- High Capacity Magazines: Typically holding 20 rounds.
- Ergonomic Design: Comfortable grip and easy-to-manipulate controls.
- Polymer Frame: Lightweight and durable.
Note: The FN Five-seveN is often associated with law enforcement and military applications due to its penetration capabilities against certain types of body armor.
FN 509 MMR
The FN 509 MMR is a more recent model from FN, a modular handgun that offers more versatility and adjustability to the user. Features include:
- Modular Design: Allows for customization and adaptability to various user preferences.
- High Capacity: Offers similar magazine capacity as the Five-seveN.
- Ambidextrous Controls: Suitable for both right- and left-handed shooters.
Choosing a 5.7x28mm Pistol: Considerations
Selecting the right 5.7x28mm pistol depends heavily on individual needs and preferences. Factors to consider include:
- Intended Use: Personal defense, competition shooting, or other specialized applications will influence your choice. The FN Five-seveN's high capacity is well suited for defense, while other models may be better for competition.
- Ergonomics: A comfortable grip and easily accessible controls are crucial for effective handling.
- Reliability: Opt for a pistol with a proven track record of reliability and consistent performance.
- Cost: 5.7x28mm pistols and ammunition can be more expensive than those in more common calibers.
Ammunition Considerations
Ammunition choices for the 5.7x28mm are important. Different manufacturers offer bullets designed for various purposes, influencing penetration and expansion. Research different ammunition types to determine which best suits your intended application. Factors to consider include:
- Bullet Type: Full metal jacket (FMJ), jacketed hollow point (JHP), or others.
- Weight: Heavier bullets generally have more stopping power but lower velocity.
- Cost: Ammunition prices can vary significantly.
Conclusion: Is a 5.7x28mm Pistol Right for You?
Pistols chambered in 5.7x28mm offer a unique set of advantages, but they are not a one-size-fits-all solution. Their high velocity, small size, and low recoil make them appealing, but their ammunition cost and debated penetration characteristics should be carefully considered. Carefully weigh the pros and cons, considering your intended use and budget, before making a purchase. Thorough research and perhaps even range time with different models will help you make an informed decision. Remember to always prioritize safety and follow all applicable laws and regulations regarding firearm ownership and use.
