One of my friends just bought a Walther CCP in 9MM. The pistol felt great in hand . The accuracy was impressive and the trigger was surprisingly good. I took the slide off and it has some kind of gas piston where the recoil spring would be in a Glock or 1911. I found the recoil to be high for a 9mm I thought 40S&W recoil impulse. It is a nice pistol. I own a Kahr PM 9 I picked up used about 10 years age as a comparison . I today would buy a Shield I have tried several at the range and I like them the best. I have a P99 S&W [Walther clone] and that is my Walther experience
