- Reliable design
- Interchangeable backstraps
- Pricey
The FN 509 is designed to be a duty weapon. This striker-fired 9mm is a nice gun packed with small features that add up to a lot. From interchangeable backstraps to an accessory rail, this gun has enough going for it to justify the price. While not a budget option, it’s a mid-tier that offers reliability and smooth shooting.
The FN 509 is a polymer pistol with a weight of around 26 ounces and a length measuring 7.4 inches. It features a fixed 3-dot sight system with combat-style sights and a capacity of 17 rounds (or 10-round mags available for states that require that). The trigger pull comes in around 5.5 to 7.7 pounds and it feels smooth while shooting. The gun is ambidextrous right out of the box, great for those lefties! The FN is a nice pistol that is worth the money.
