Choosing the right firearm is crucial for tactical professionals. This in-depth comparison analyzes two distinct handguns from FN Herstal: the FN FNX-45 Tactical and the FN Five-seveN (FN 5.7). We'll delve into their features, performance, and suitability for various tactical roles, helping you determine which weapon best fits your operational needs. Both the FNX-45 Tactical and the FN 5.7 are highly regarded, but their strengths lie in different areas.
Caliber and Ballistics: A Fundamental Difference
The most significant difference between these two handguns lies in their caliber. The FNX-45 Tactical utilizes the powerful and widely used .45 ACP cartridge, while the FN 5.7 employs the smaller, high-velocity 5.7x28mm round.
-
FNX-45 Tactical (.45 ACP): This round delivers substantial stopping power, making it effective for close-quarters combat (CQB) and self-defense scenarios. Its larger diameter and heavier weight cause significant tissue damage upon impact. However, its heavier recoil can be a factor for some shooters.
-
FN 5.7 (5.7x28mm): The 5.7x28mm round is known for its high velocity and flatter trajectory. Its smaller size allows for higher magazine capacity, and its piercing capabilities make it effective against soft body armor. While stopping power might be debated compared to the .45 ACP, its superior penetration and reduced recoil can offer tactical advantages in specific situations.
Table 1: Caliber Comparison
| Feature | FNX-45 Tactical (.45 ACP) | FN 5.7 (5.7x28mm) |
|---|---|---|
| Caliber | .45 ACP | 5.7x28mm |
| Stopping Power | High | Moderate to High |
| Penetration | Moderate | High |
| Recoil | Higher | Lower |
| Magazine Capacity | Lower (typically 14 rounds) | Higher (typically 20 rounds) |
Ergonomics and Handling: Comfort and Control
Both pistols are designed with ergonomics in mind, but their differences in size and weight contribute to distinct handling characteristics.
-
FNX-45 Tactical: This full-sized pistol offers a substantial grip, providing excellent control, especially during rapid firing. Its weight helps to mitigate recoil, although some users might find it cumbersome for extended periods.
-
FN 5.7: The FN 5.7 is considerably lighter and more compact than the FNX-45 Tactical. Its smaller size makes it easier to conceal and maneuver in tight spaces. However, its lighter weight can amplify perceived recoil for some shooters.
Features and Accessories: Tailored for Tactical Use
Both models boast features suitable for tactical applications, but with some notable variations.
-
FNX-45 Tactical: Typically features a rail for mounting tactical accessories like lights and lasers. Many models offer ambidextrous controls, making it adaptable for both right- and left-handed users. The larger frame allows for more robust sights.
-
FN 5.7: Often includes an accessory rail and ambidextrous controls. However, the compact size might limit the size and type of accessories that can be effectively mounted.
Ammunition Considerations: Cost and Availability
Ammunition costs and availability are essential factors for any tactical professional.
-
FNX-45 Tactical (.45 ACP): .45 ACP ammunition is widely available and relatively inexpensive compared to some specialty rounds.
-
FN 5.7 (5.7x28mm): 5.7x28mm ammunition is generally more expensive and may have limited availability in some regions.
Conclusion: Selecting the Right Tool for the Job
The choice between the FN FNX-45 Tactical and the FN 5.7 depends heavily on the specific tactical requirements.
-
Choose the FNX-45 Tactical if: You prioritize stopping power, require a robust platform for accessories, and are comfortable managing higher recoil. Its performance in close-quarters combat is superior.
-
Choose the FN 5.7 if: You need a lighter, more concealable handgun with higher magazine capacity and superior penetration against soft body armor. The reduced recoil and flatter trajectory can be advantageous in certain tactical scenarios.
Ultimately, handling both pistols and understanding your specific operational needs will be the most decisive factors in making the right choice. Consider renting or borrowing both handguns for range time before making a significant investment.
