The FN 509 CO2 BB pistol is a fully licensed replica of the FN Herstal 509 service pistol, made under licence by Cybergun and distributed in the UK by Bisley. It runs on a single 12g CO2 capsule housed in the magazine and cycles a genuine blowback action on every shot, with a metal slide carrying stamped FN Herstal trademarks for an authentic look and feel. The 17-round magazine feeds 4.5mm steel BBs, and an adjustable hop-up helps keep shots consistent for plinking and target work, with power up to 315 fps. Ambidextrous slide and magazine controls suit right- and left-handed shooters alike, and tri-dot combat sights aid a fast, accurate sight picture. A 20mm accessory rail under the ABS frame's dust cover takes lights or lasers from the wider replica range. Compact and light at 21.9cm and 0.80kg, it is built for back-garden and range plinking rather than hunting or pest control, and as an air weapon is restricted to buyers aged 18 and over.
