I've got an Umarex HK MP5-22 that's outstanding, and from posts here there are others who feel the same. But I hear nothing good about anything else Umarex makes. And to most buyers, I don't think they distinguish that a P22 is Umarex, not Walther. I don't expect a P22 to be as good a quality as my PPS but when it becomes a jam-o-matic to a new buyer it's left a bad taste in their mouth for all Walther products, Same for the Sig Mosquito, if that's the first Sig you bought it'd probably be your last. I know price is a factor, it's not fair to compare a $250 P22 or Mosquito to a $350-$400 Ruger .22 or S&W MP-22. But that's little consolation when the zinc slide on your 6 month old pistol breaks in half.
