The Walther CP 88 is a sport and training pistol that shoots pellets using compressed
CO2 according to the principle of an
air gun
An air gun or airgun is a gun that fires projectiles pneumatically with compressed air or other gases that are mechanically pressurized ''without'' involving any chemical reactions, in contrast to a firearm, which pressurizes gases ''chemica ...

Walther P88
The Walther P88 is a semiautomatic pistol developed by German company Walther. Its main feature is a high-capacity double-stacked magazine designed for military and law enforcement use. The P88 was succeeded by the Walther P99 in 1997.

(for example shooting at cans) steel core pellets can also be used, which are offered by some manufacturers in the required maximum length. In order to ensure that the cylinder functions properly, pellet lengths of no more than 6.9 mm (6.5 mm according to the manufacturer's specifications) are possible, as the height of the cylinder is 7 mm.

of standard diabolos with a newly inserted CO
2 cartridge is specified as 120 m/s ("Competition" as 130 m/s). This speed is continuously reduced because the gas pressure decreases after each shot. This is especially important when firing in quick succession, as this leads to a reduction in temperature in the weapon itself as well as in the CO
2 cartridge, which reduces the muzzle velocity. At normal room temperatures, it should be possible to fire about 50 rounds with one CO
2 cartridge without any loss of accuracy. The gun shoots precisely at a distance of up to about 20 m. Both the single-action and the double-action system can be used as

The pistol is made of metal like its model and weighs 1040 g, in the "Competition" version 1150 g. Loaded and with a
silencer attached, up to 1300 g or even more can be achieved. This high degree of similarity to the P88 offers the sports shooter a considerable level of realism for training shooting.

With the aid of an adapter, the pistol can be equipped with a third-party silencer. Depending on the silencer, the noise level is reduced from just under 80

s to about 70 decibels. Depending on the type, the silencer makes it impossible to acquire a target through the attached open sight. In this case, the use of an illuminated
dot sight via an adapter rail would be worth considering. A laterally adjustable, open sight is premounted as standard. This can be replaced by a height-adjustable visor, which is offered as an optional extra. As the CP 88 has an interchangeable
