Was shooting my PM9 Saturday and something was very wrong, I was actually shooting pretty good...The pistol now has 250 rounds through it and not missed a beat but when I got it home and started to clean it I noticed the little nut on the end of the recoil spring assembly had fallen off which seems to be a common problem so I called Kahr this morning and Rob picked up right away and was very nice to work with and has a new assembly in the mail to me....Can't ask for better than that....Thanks Rob and Kahr for the great customer service....I hope the new assembly stays together for a little longer this time....
