Not easily, not without modification, and not without a sight installation/adjustment/removal tool. I was able to modify the base of the rear sight to fit the dovetail cut in the slide, but the sight still fits too tightly to use the windage adjustment screw. I removed the screw and set the rear sight in with a Universal Pistol Sight installation/adjustment/removal tool I bought on ebay a while back when I needed to install sights on my Glock 42. I decided to try these since I was having trouble locating Night Sights for the CCP M2. Even Walther's website says these fit the CCP M2 and the CCP. Well, not easily. I have read where others have taken their sights and pistol to a gunsmith to have them installed and they report good results. YMMV.
