I have to say that I really wonder about whether Walther got this gun right. I read all of the criticisims out there, but was under the impression that they had corrected the problems as the gun evolved. I went to the range and had the keyholing problem I mentioned on a separate string. Between that, the walking safety, the tendency of screws and bolts to come loose over time, etc., I really have to wonder if I threw my money away on a purchase that I thought would save me money. The main reason why I boiught my P22 is that the controls are very similar to my HK (sights, magazine release, location of safety) and I thought I could shoot .22 ammo cheaply, while still maintaining my "muscle memory" that I will need if I ever ned my .45 for home defense.
