I got this replica Walther PPK/S with Co2 as a BB gun 6 months ago, and use it for target practise and recreational fun. It feels and acts as a real gun. Plus it is the same gun used in the James Bond movie, so it has gained a lot of popularity for that reason. Maybe unrelated to that, because it is entirely made of metal, and looks, acts and feels like a real gun, even when firing, it is recommended by the NRA for beginners who want to get to know how to use a gun, without the formal paperwork necessary in some states. In Europe, where gun restrictions are even more tight, such a gun is a great place to start if you want to get to do some shooting without the obsessive licensing requirements. A video on youtube shows its characteristics when shooting.
