Walther is also particularly proud of their magazines. For the pps, ppq, and p99 factory mags tend to run in the $40-50 range.
That's why you buy the Magnum Research Fast Action mags for the PPQ and P99 for $32 each. They are the exact-same Mec-Gar manufactured mags as those sold by Walther. The only difference is the name molded into the baseplate.
