I don't know about mag springs in .22lr for the PP or PPK/S
however for sure you can call Earl and ask him about it... he might even have some used mags for the .22lr for cheaper than new ones.....

I can give you a lead on new (original Walther/no banner) mags....

I bought a PP in .22lr
and the first thing after getting it was looking for NIW mags
I bought 4 from the above place.... good deal I think
