The CX22 by American Arms is a Walther PPK look-alike in .22LR. I have one and it is not too bad, although I won't use Stingers in it again. I had one stinger blow out part of it's rim, since the rim is not supported 360 degrees. There is a gap at the top, where the Stinger rim blew out. I believe they were originally built by Erma in Germany. Although they are a casualty to the anti's lawsuits, they were being made in Kansas City when I bought mine. Curiously, the frame is marked "made in USA", while the slide is stamped "made in Germany"..
It does however, shoot good with regular high speed rounds. Just wanted to get comments from others that may own, or have used one.
