Trigger Mechanism: The Umarex Walther CP99 features a medium-strength double-action trigger, with the primary effort focused on the initial and middle phases for hammer cocking and magazine indexing. It provides a consistent point of release, aiding in accurately firing pellets. Engaging the rear slide switches the CP99 to a single-action mode, significantly reducing trigger weight and enhancing shot precision.

Shot Accuracy: In my testing from a semi-supported stance 20 feet away, the CP99 exhibited commendable accuracy, grouping shots within one inch to the left of the target. The adjustable sights for windage compensate for off-center aiming. Preliminary speed tests with 6.9-grain RWS lead pellets showed an average velocity of approximately 346 fps, closely aligning with the stated 360 fps.

Construction: The Umarex Walther CP99, a blend of metal and polymer, boasts substantial internal metal components, contributing to its overall solid feel. A notable feature is the full-size magazine that holds the CO2 cartridge, adding to the pistol's weight and functionality. This German-made air pistol showcases excellent craftsmanship and high-grade plastic components.

Realistic Design: Officially licensed by Walther, the CP99 mimics the Walther P99’s frame but differs slightly in the slide design. While the CP99 replicates the P99’s appearance, its safety feature deviates from the original, with an oversized safety placed on the right slide. Despite this, the functioning de-cocker, slide catch, and full-size magazine enhance its realistic attributes.


  • Realistic and functional slide catch and de-cocker.
  • Precision rifled barrel.
  • Windage-adjustable sights.
  • Fully operational slide catch and magazine release.
  • Substantial full-size CO2 magazine.
  • Effective balance of power, accuracy, and CO2 efficiency, yielding about 100 shots per cartridge.
  • Accessory rail included.
  • Walther license.
  • German manufacturing quality.


  • Priced at the higher end of the spectrum.
  • Occasional stiffness in double-action shots.
  • Unconventional safety feature, differing from the genuine Walther P99.
  • Absence of a recessed barrel.


The Umarex Walther CP99 CO2 Pellet Air Pistol represents an upgrade from the previously reviewed Walther CP Sport. More accurately resembling the P99, it incorporates additional metal components and both single and double-action triggers, enhancing its authenticity. Though this model comes with an increased price tag of around $100, it justifies its value through improved features. For Walther enthusiasts, the CP99 is a highly recommended addition to any airgun collection, offering a balance of quality, realism, and functionality.
