Italian shops sell versions tuned below 1 J: ask the shop which version they ship.
Energy computed from the velocity with 0.20 g BBs, the standard weight manufacturers and shops use to measure FPS.
The main source does not give the velocity: FPS taken from the page of the same model on www.airsoftzone.com.
For information only, based on the source's data for this version. Not legal advice: always check current local law and the version the shop sells.
