If you love shooting the Walther PPQ or have always wanted to own one, the Walther PPQ CO2 Air Pistol great economical alternative for training and shooting fun. The PPQ Air Pistol looks and feels just like the real PPQ, and has the same excellent balance in hand. The pistol operates on one 12 gram CO2 cartridge that is stored in the grip. The PPQ will shoot both pellets and BBs. The metal 8-shot rotary magazine is designed to hold pellets, and the polymer 8-shot rotary magazine holds BBs. The BBs should fit tight in the magazine, so if they are loose when you load them the magazine it is probably upside down. Flip the magazine over and the other side should hold the BBs tightly. The fixed front sight and adjustable rear sight, along with the rifled barrel, allow for superb accuracy with pellets. The PPQ also sports a picatinny rail for mounting lasers or a tactical flashlight.
