Ergonomics:
The FN 509M is a mid-sized handgun that, although small, has excellent ergonomics. The grip angle is slightly lowered to match the user's arm, while the slide serrations and grip texture provide a reliable grip. The magazine and slide release are easy to access and manipulate, and the ambidextrous slide stop makes it easy to use either hand.

Build Quality:
The FN 509M is built to withstand long-term use and high-stress scenarios. The frame and slide are constructed from steel, with a matte black finish that resists corrosion and wear. The gun is well put together, with tight tolerances, and no noticeable play or rattle when shaken. It is a heavy-duty firearm that is sure to stand up to whatever you throw at it.
Performance:
The FN 509M is an incredibly reliable handgun, with excellent out-of-the-box accuracy. The trigger is smooth and responsive, with minimal creep and a short reset. The trigger itself has a total pull weight of 5.5 pounds, with a distinct click when reset. The gun is also equipped with a recessed target crown, which helps to keep the muzzle centered when shooting and aids in accuracy. Additionally, the FN 509M features a sighting system that can be adapted for any shooting style, with fixed 3-dot sights as well as a MIL-STD-1913 Picatinny rail. The slide is also well-designed, featuring a short slide-lock lever that helps reduce the chance of the slide being inadvertently released when manipulating the slide.
Accuracy:
The FN 509M is incredibly accurate for a mid-sized handgun. From a standard 25 yard bench rest test, the gun was able to consistently produce sub 1-inch groups for center of mass. At 50 yards, the accuracy was better than expected, with groups staying within a 2-inch circle for the entirety of the test.

The recoil is minimal, allowing for quick follow-up shots, while the ergonomic grip makes it easy to maintain a consistent grip on the gun.
