Choosing the right handgun is a deeply personal decision, influenced by factors ranging from intended use to individual hand size and shooting style. When comparing two handguns from the same reputable manufacturer, like the FN FNX-45 and the FN Five-seveN (often referred to as the FN 5.7), the choice becomes even more nuanced. This in-depth comparison will analyze the key differences between these two distinct firearms, helping you determine which best suits your needs.
Caliber: The Defining Difference
The most significant distinction between the FNX-45 and the FN 5.7 lies in their caliber. The FNX-45 fires the powerful .45 ACP cartridge, known for its stopping power and substantial recoil. In contrast, the FN 5.7 uses the smaller, high-velocity 5.7x28mm cartridge, renowned for its flat trajectory and penetration capabilities. This fundamental difference dictates many of the other variations between the two pistols.
Stopping Power vs. Penetration: Which is Right for You?
The .45 ACP's large diameter and significant mass translate into exceptional stopping power, making it a favored choice for self-defense and law enforcement. However, this comes at the cost of increased recoil and muzzle flip, demanding more practice and potentially hindering rapid follow-up shots for some shooters.
The 5.7x28mm cartridge offers superior penetration, making it effective against barriers like car doors and body armor (though this effectiveness against modern body armor is debated and dependent on the specific armor's construction). Its lower recoil makes it easier to control and allows for faster follow-up shots, beneficial in rapid-fire scenarios. The trade-off is a perceived reduction in stopping power compared to the .45 ACP, although this is a topic of ongoing discussion amongst firearms experts.
Ergonomics and Handling: A Matter of Preference
Both handguns boast ergonomic designs, although their feel in the hand varies significantly. The FNX-45, with its larger frame to accommodate the .45 ACP cartridge, is better suited for shooters with larger hands. The FN 5.7, being a smaller, lighter pistol, may feel more comfortable for shooters with smaller hands or those who prioritize concealability.
Key Ergonomic Considerations:
- Grip Texture: Both pistols generally feature aggressive texturing for a secure grip. However, the specific texture and overall feel can be subjective.
- Slide Serrations: The location and aggressiveness of the slide serrations can impact ease of manipulation during reloading.
- Ambidextrous Controls: Both pistols offer ambidextrous controls for enhanced usability by left-handed shooters.
Capacity and Magazines
The FNX-45 typically holds 15 rounds in standard magazines, with higher-capacity options available in certain jurisdictions. The FN 5.7 generally carries 20 rounds in standard magazines, significantly increasing its ammunition capacity. The availability of extended magazines for both models can also further impact capacity.
Recoil and Shootability
As previously mentioned, the FNX-45's .45 ACP cartridge produces noticeably more recoil than the 5.7x28mm. While experienced shooters might manage this recoil effectively, it can be challenging for beginners. The FN 5.7's lighter recoil makes it more manageable for a wider range of shooters, especially those new to handguns.
Conclusion: Choosing the Right Tool for the Job
The choice between the FN FNX-45 and the FN 5.7 depends entirely on your individual needs and priorities. The FNX-45 excels in stopping power and is a reliable choice for self-defense where maximum immediate incapacitation is paramount. The FN 5.7, with its higher capacity, flatter trajectory, and lighter recoil, makes an excellent choice for scenarios demanding rapid fire and potential penetration through barriers. Consider your intended use, hand size, and experience level before making a final decision. Visiting a range to test fire both models is strongly recommended.
