The PX4 Storm looks, feels, and shoots just like the real firearm! This 16-shot repeater will have you shooting as fast as you can pull the trigger. There's an 8-shot rotary clip on one end of the stick mag, and another one at the other end. After you're done shooting the first clip, flip the mag for the rest of the shots! Since it shoots BBs or pellets, you'll have more flexibility with ammo choice. A 12-gram CO2 is easily loaded into the grip and gives you plenty of shots before you need a refill. There's even an accessory rail under the barrel. Like the handgun, it has real blowback action giving you a feeling of power that most airguns only hope to achieve! Once you start shooting, you won't want to stop, so get lots of RWS pellets, BBs and Walther CO2.
