The FN 509, produced by FN America LLC, the US branch of FN Herstal, S.A., a global leader in development and manufacture of high-quality and dependable firearms, is FN-America's Tactical firearm based on FN's submission to the U.S. Army during their Modular Handgun trials. But FN didn’t stop there. FN includes significant improvements to that original design and have included them in the commercial release of the FN509 Tactical FDE.

Right out of the gate, FN-America LLC, produces the FN509 Tactical FDE with the company’s U.S. Patent No. 10/352,654 Low-Profile Optics Mounting System ™ which enables the pistol to accommodate more than ten commercially available red dot (MRD) optics. And if that’s not enough for you, not only do can these red dot (MRD) optics co-witness with the suppressor-height night sights but the platform of the FN509 is adaptable to future optic releases without requiring a direct milling of the slide. Nothing says building for the future, like the FN509 Tactical FDE.FN-America LLC has packed so many improvements into the FN509, including a slide cap used when not shooting with an optic. The cap has raised sight wings that protect the iron sight alignment if the pistol is dropped or bumped. It also has a textured ramp for racking the slide against a belt loop or a pant pocket.With its signature 4.5’ cold hammer-forged, stainless barrel and target crown half inch by 28 threads to accept the bulk of 9mm suppressors available, the FN509 not only can accurately fire a round, but can do it whisper quiet.The thread cap with integrated O-ring designed to prevent loosening during use, is just another in a long list of valued features which places the FN509 in the winner’s circle in the race to develop a premier handgun. And just when you thought FN-America LLC couldn’t possibly build a better firearm what did they do? They built this FN509 to handle 24-round magazines. Which is a huge plus when you consider most standard 9mm pistol magazines average from 6 to 18 rounds.And not only did FN-America LLC, increase the capacity of the FN509, but they did it in such a way it won’t impact convenience of carry. As Tactical pistols go, and for the money, the FN509 Tactical FDE is one of the best on the market today.
