I have a Walther CCP M2 in 9mm & agree that it does fit the hand well. It’s a delayed blowback, & the only issue I’ve had so so far, is an occasional non firing when pulling the trigger. A re-rack solved the issue each time & I even fired the ejected cartridges in question each time successfully. I was demonstrating several sub compacts at the time so I didn’t look at it closely. I’ll take it separately to the range to see if it happens again after I completely cleaned it a second time. Perhaps it was the ammo, or light primer strikes, who knows. When working properly, it was fine and felt good Shooting.
