The successful full metal replica from Swiss Arms with an energy of approx. 2.75 joules is operated with Co2. The model has a fixed slide, through which less Co2 is consumed.
Air guns (air pistols and air rifles under 7.5 joules) must have an -F- marking in the pentagon. The acquisition, possession and transport of the weapons is allowed to adults without a gun license. However, they are subject to the ban on carrying (§42 a WaffG).
