I bought the CP3 that was recently on gunstar.

Shot it for the first time this week, really pleased with it. Also bought a second cylinder off of a well know auction site as it only came with one cylinder.

The CP1,2,3's (or the early Feinwerbau Co2 pistolds) don't appear to sell for very much, maybe because they are Co2 based?

Good to know that someone has spare valves and seals too

Has anyone seen/shot a Walther CP5?
