I don't have any experience with the PPS but do with Kahr pistols from the beginning. I owned a K9, P40,CW9, amd CM9. I had some problems with the K9 and P40. Nothing but praise for the CW9 and CM9. Guzyk's Gun shop in Ambridge PA currently has the Cm9/CM40's for $385.00 plus tax.Good luck in your search.tom.
Thank Goodness we're back on line.
An end will come on the world, but love and music will endure.
Thig crioch air an t-saoghail, ach mairidh gaol 's ceol.
