The Beretta PX4 Storm CO2 air pistol is a lot of fun to shoot and fires both .177 pellet and BB.

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.
