I acquired a new Walther P22. The first time at the range the second round in each magazine would not feed. I called the factory and sent it back. Upon return the same problem continued. A second call revealed that the factory had no problems; they shot CCI Mini-Mags for their test. I found some CCI Mini-Mags and shot 60 rounds without a problem! Has anyone had a similar problem and were you able to find other brands of ammo that works in the pistol?
