The 5.7x28mm cartridge, initially designed for military and law enforcement applications, has gained popularity among civilian firearm enthusiasts. This article explores guns that shoot this unique round, examining their features, applications, and considerations for responsible ownership. We'll delve into the ballistics, advantages, and disadvantages of the 5.7x28mm, providing you with the information you need to make informed decisions.
Understanding the 5.7x28mm Cartridge
The 5.7x28mm cartridge is a small-caliber, high-velocity round known for its impressive penetration and accuracy at close to medium ranges. Unlike larger rounds, the 5.7x28mm prioritizes velocity over sheer stopping power. This characteristic makes it particularly suitable for certain applications.
Ballistics and Performance
| Characteristic | Value |
|---|---|
| Caliber | 5.7x28mm |
| Bullet Weight (grains) | Typically 28-40 |
| Muzzle Velocity (fps) | Upwards of 2600 fps |
| Effective Range (m) | ~200-250 (depending on bullet type and firearm) |
| Penetration | Significant through soft barriers, reduced penetration in hard barriers |
The high velocity results in a flatter trajectory, meaning less bullet drop over distance compared to larger calibers at the same range. However, the smaller bullet's design and lower mass can make it more susceptible to wind deflection.
Advantages of 5.7x28mm Handguns
- High Velocity: Leads to superior accuracy at longer ranges.
- Penetration: Capable of penetrating soft body armor and light barriers.
- Low Recoil: Makes it easier to control and shoot rapidly.
- Lightweight Ammunition: Reduces the overall weight carried by the user.
Disadvantages of 5.7x28mm Handguns
- Stopping Power: Debate surrounds its effectiveness in stopping threats compared to larger calibers. The smaller bullet may require precise shot placement.
- Cost: 5.7x28mm ammunition can be significantly more expensive than other commonly used calibers.
- Availability: May be less readily available than other calibers in certain regions.
- Overpenetration: Although a concern with most firearms, 5.7x28mm rounds, due to their speed, have a larger overpenetration potential than others.
Popular Guns That Shoot 5.7x28mm
Several manufacturers produce firearms chambered in 5.7x28mm, catering to various needs and preferences. Here are some notable examples:
FN Five-seveN Pistol
The FN Five-seveN is arguably the most well-known pistol chambered in 5.7x28mm. Designed by Fabrique Nationale (FN), it's known for its sleek design, high capacity magazines (often holding 20 rounds or more), and relatively low recoil.
FN PS90 Personal Defense Weapon (PDW)
The FN PS90 is a compact personal defense weapon designed for close-quarters combat. Its bullpup design (where the action is located behind the trigger) contributes to a shorter overall length despite having a longer barrel. This results in improved accuracy and velocity.
Other 5.7x28mm Firearms
While FN holds a dominant position in the 5.7x28mm market, some other manufacturers offer firearms in this caliber, although the selection is smaller. Research and check local laws before purchasing.
Legal Considerations and Responsible Ownership
Before purchasing any firearm, it's crucial to understand and comply with all applicable federal, state, and local laws and regulations. Responsible gun ownership involves safe handling, storage, and proper training. Always prioritize safety and familiarize yourself with the firearm's operation before handling it.
Choosing the Right 5.7x28mm Firearm
The decision of whether or not a 5.7x28mm firearm is right for you depends on your individual needs and circumstances. Consider the following:
- Intended Use: Self-defense, sport shooting, or collection?
- Experience Level: Are you a novice or experienced shooter?
- Budget: Ammunition and maintenance costs can vary significantly.
- Legal Restrictions: Check local laws and regulations.
Conclusion: Weighing the Pros and Cons of 5.7x28mm Firearms
5.7x28mm firearms offer a unique combination of advantages and disadvantages. Their high velocity and penetration capabilities are attractive to some, while concerns about stopping power and cost remain points of debate among shooters. Ultimately, the decision to own a 5.7x28mm firearm should be made after careful consideration of all aspects, including personal needs, legal compliance, and responsible gun ownership practices. Thorough research and consultation with knowledgeable firearm professionals are recommended.
