Where can you get a ppk CO2 gun in the UK?

PPK CO2 guns are not available in the UK due to the Violent Crime Reduction Act of 2006, which prohibits the sale, manufacture, and importation of certain types of firearms, including realistic imitation firearms (RIFs). PPK CO2 guns are considered RIFs because they closely resemble the Walther PPK pistol, a real firearm.
