EMG/FN Herstal FN509 Gas Blowback Airsoft Pistol in Black

Modern, reliable, and ready for any mission—meet the EMG/FN Herstal FN509 Gas Blowback Airsoft Pistol. This fully licensed airsoft pistol is a near-perfect replica of FN Herstal’s striker-fired FN509, known for its real-world use by tactical professionals and its role in the U.S. Army’s XM17 Modular Handgun trials. Thanks to the combined expertise of EMG and Cybergun, this pistol delivers not just visual authenticity but skirmish-grade performance you can count on.

The FN509 immediately impresses with its realistic proportions and construction. A nylon-reinforced polymer frame keeps the weight manageable while offering excellent durability, and the aluminium alloy slide feels crisp and sturdy when racking or firing. The controls are fully ambidextrous—mag release, slide catch, and safety—all positioned for intuitive, fast operation whether you’re right or left-handed.

The slide is pre-cut for RMR optics, so adding a red dot is a breeze. You won’t have to sacrifice iron sight alignment either, as the suppressor-height fibre optic sights offer a bright, high-visibility aim point even when a reflex sight is mounted. Tactical serrations front and rear make racking easy under pressure, and the threaded 14mm CCW barrel lets you add suppressors or compensators to tailor the look and function of your sidearm to your style of play.

Under the hood, this GBB pistol is built with performance in mind. The reinforced internal system includes steel sears and precision ball bearings for smooth operation and improved longevity. The dual recoil spring design and advanced gas nozzle provide satisfying recoil with quick cycling, delivering 295 FPS with 0.20g BBs—ideal for most CQB and mid-range outdoor environments.

It’s not just accurate—it’s consistent. Expect tight groupings at around 20 metres, thanks to the well-tuned hop-up and barrel setup. The included 20+1 round green gas magazine performs reliably and can typically cycle two full loads before needing a refill. Reloads are fast and positive, and gas efficiency is excellent for its size and blowback strength.

Ergonomics are another standout feature. The grip is aggressively textured for a secure hold in all conditions, and you can swap the backstraps to better fit your hand. A Picatinny rail up front gives you the option to mount torches or lasers, making this pistol extremely adaptable for indoor or low-light play. It's a sidearm that doesn't just look the part—it functions like a real tactical tool.

Whether you're looking for a modern alternative to the usual Glock-style builds or want a faithful replica of a battle-tested real-world handgun, the FN509 delivers in spades. With authentic FN trademarks, premium construction, and user-friendly features, this pistol is built for those who want a dependable and stylish backup—or even a primary—in the field.
