Choosing a handgun for personal defense, competition, or even just recreational shooting is a big decision. Two popular choices often top the list for many shooters: the FN 545 and the FN FNX-45. Both are reliable, high-quality firearms from Fabrique Nationale (FN), but they cater to slightly different needs and preferences. This in-depth comparison will help you decide which pistol is the right fit for you.
Caliber and Capacity: A Key Difference
The most significant difference between the FN 545 and the FN FNX-45 lies in their caliber.
-
FN 545: Chambers the increasingly popular 5.45x39mm cartridge. This round, known for its high velocity and flatter trajectory, offers excellent stopping power at longer ranges. The 545 typically holds 15+1 rounds in its standard magazines.
-
FN FNX-45: This pistol fires the potent .45 ACP cartridge, a proven round known for its substantial stopping power at close range. It's a larger, heavier round than the 5.45x39mm. The FNX-45's standard magazine capacity is typically 15+1 rounds.
While both offer high capacity, the choice depends heavily on your intended use and preference for cartridge ballistics. .45 ACP's heavier recoil might make it less suitable for new shooters or those prioritizing rapid follow-up shots. The 5.45x39mm, while powerful, offers less felt recoil which can facilitate faster shooting.
Size and Weight: Ergonomics and Concealed Carry
Size and weight are critical considerations, especially for concealed carry.
| Feature | FN 545 | FN FNX-45 |
|---|---|---|
| Overall Length | Approximately 7.4 inches | Approximately 7.4 inches |
| Weight (Unloaded) | Approximately 26.6 oz | Approximately 32.5 oz |
| Slide Material | Steel | Steel |
| Frame Material | Polymer | Polymer |
While overall length is similar, the FN FNX-45 is noticeably heavier due to the larger and heavier .45 ACP cartridge and its robust construction. The increased weight can be beneficial in mitigating recoil, but can make it less comfortable for all-day carry. The FN 545's lighter weight makes it a more practical choice for concealed carry for those who prioritize comfort and ease of concealment.
Features and Controls: Ambidextrous Options and More
Both pistols share many similar features designed for ease of use and reliability, including:
-
Ambidextrous controls: Both the slide release and magazine release are ambidextrous. This is a huge plus for both left and right-handed shooters.
-
Durable Construction: Both firearms are renowned for their robust construction, able to withstand considerable wear and tear.
-
Accessory Rail: Both feature a Picatinny rail under the barrel for mounting accessories like lights and lasers.
-
Interchangeable Backstraps: Both pistols come with interchangeable backstraps allowing users to customize the grip.
However, subtle differences exist. Some users find the FN FNX-45's grip slightly more ergonomic, particularly for larger hands. The FN 545’s ergonomic design is still excellent and preferred by many shooters.
Accuracy and Reliability: Performance on the Range
Both the FN 545 and the FNX-45 have earned reputations for exceptional accuracy and reliability. These are battle-proven firearms designed for demanding environments. Extensive testing by various sources consistently demonstrate both pistols' ability to function flawlessly under stress, with minimal malfunctions.
The perceived accuracy difference between the two comes down to shooter preference and the ammunition used. The flatter trajectory of the 5.45x39mm cartridge from the FN 545 could arguably give it a slight edge at longer ranges for experienced shooters. However, the .45 ACP's substantial stopping power at close range remains a significant advantage in self-defense situations.
Price Point: A Factor to Consider
Expect to pay more for the FN FNX-45 due to the larger cartridge and some extra features. This is a key factor in deciding which handgun is the better buy for you, based on your budget.
Conclusion: The Best Choice Depends on Your Needs
Choosing between the FN 545 and FN FNX-45 ultimately comes down to individual needs and priorities.
-
Choose the FN 545 if: You prioritize a lighter, more manageable firearm for concealed carry, prefer the ballistics of the 5.45x39mm, and value a slightly more affordable option.
-
Choose the FN FNX-45 if: You require maximum stopping power at close range, prefer the .45 ACP cartridge, and don't mind the extra weight.
No matter your choice, both the FN 545 and FN FNX-45 represent high-quality, reliable firearms that will serve you well. Always remember to practice safe gun handling and seek professional training before carrying any firearm.
