About

What it is, and why it matters

Copy a link to this section

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

Studio

Every part that mounts on this, resolved

Not a list the maker typed out: the answer comes from the mounts this firearm exposes and the interface each part needs, so it stays right when either one changes.

  • Every part that mounts on any firearm in the catalogue
  • Interface standards, platforms and fit overrides
  • The same answers through the API and the MCP server

Requires a signed-in GunSpec account on the Studio plan. The answer is computed per part, so it is not part of the public record.
