About
What it is, and why it matters
The Walther CP99 is a CO2-powered semi-automatic air pistol chambered for .177 (4.5mm) lead pellets, manufactured by Umarex under official license from Carl Walther. A faithful replica of the Walther P99 service pistol, it uses a 12-gram CO2 cartridge housed in a removable magazine and an 8-shot rotary pellet magazine that seats in the slide. It offers both single- and double-action trigger operation and is widely used for target practice and plinking.
The CP99 mirrors the Walther P99, a pistol closely associated with James Bond, who switched from the classic PPK to the P99 in the film series, making the air-pistol replica a popular collector's item.
Powered by a single 12-gram CO2 capsule giving roughly 80-100 shots. Popularised in film as a screen prop resembling James Bond's Walther P99.

Trajectory
What the round does downrange
Solved from the muzzle figures and the bullet. The dashed rule is the effective range on the record, and the crosses are the steps the solver returned.
No load solved for this record yetThe flight path is computed from a cartridge and a bullet. This record has no ammunition filed against its chambering, so there is nothing to solve.
