I'm noticing the NIB Walther P22 at a local gunshops getting cheaper and cheaper. Is this because of the influx of new .22 pistols from other companies? Is it because S&W/Walther never improved on the design? Are the one on the shelves now , as bad as the one that had problems back in the day. Anyone still have a Walther P22, with a lot of use and rounds downrange, or have they all been traded away.
