Walther CP99 Compact – Blowback Action Semi-Auto Part 1
Walther’s Concealed Carry P99 model on Air
By Dennis Adler
When Carl Walter GmbH introduced the .177 caliber CP99 air pistol some 15 years ago, it was a bold new design that helped launch the current generation of air pistols based on real, cartridge-firing semi-autos. Today, that same model is still among the most popular of all Umarex Walther CO2 models, but the original CP99 lacked one essential feature that really sells semi-auto air pistols today, a blowback action.
