I have a first generation, pre-M2 "M1" Walther PPS.  These are getting impossible to find/pry away from their owners.  This pistol was a 2nd or backup pistol for a Federal LEO that carried a PPS everyday.  Proportedly it was fired once or twice on the range next to his carry gun to confirm function and otherwise kept in a safe.  The PPS was one of the first polymer-frame single-stack 9mm, striker-fired concealment pistols on the market, and it is still the finest in my opinion.  This is a German made pistol and is made to last, and work everytime.  Please don't hesitate to reach out if you have any questions at all.
