Under the Firearms and Ammunition Ordinance, Cap. 238, any person who, without a licence or an exemption issued by the Commissioner of Police, has in his possession any air rifle, air gun or air pistol from which any shot, bullet or missile can be discharged with a muzzle energy greater than 2 joules commits an offence and is liable to a fine of $100,000 and to imprisonment for 14 years.
Guns Galore out Killeen had one of those back in 2006. They also had no clue how to get ammo for it. I think they were selling it as a novelty for $299.Odd revolver AND even odder round. A mere handful (literally) of the rounds have gotten to US collectors, as the round is highly restricted in China. The idea is limited lethality and limited criminal use once the cylinder is empty.
