Hi dragonfly,
Take a look at the posts under the Walther Rimfire section.
even though my P22 has the latest "A" magazines, I've had my share of issues with it. Do I still like it? Yes.
I do need to check the firing pin spring tonight, due to those light strikes. Some owners have had no problems after break-in. Just depends on the particular P22.
Regarding NIB price, local here in MA:
3.42", $239
5", $289
