Update by user Jul 02, 2021 Walther Arms responded quickly and way beyond my expaectations. Original review posted by user Jun 26, 2021 I watched an internet video which showed the P22 being field stripped including removing the barrel nut and sleeve from the barrel. I subsequently followed that procedure and found the barrel nut difficult to remove. Eventually removing forcefully with pliers, I damaged the finish with deep scratches. How can I order a replacement barrel nut for this CA model? I now understand it was installed with locktite. User's recommendation: Don't follow internet blog procedures blindly. The difficulty I had should have warned me something was a problem.
