Umarex. The powerful blowback effect of this CO₂ pistol makes for very realistic shooting.

One special feature is the magazine with two 8-shot cylinders. After emptying one cylinder, the shooter just has to take out the magazine and turn it around to get eight more shots. This works for BBs as well as 4.5 mm pellets. The Px4 Storm can take both kinds of ammunition. The safety slide for decocking is another important detail.
