Congratulations. My experience with the S9 has been completely positive. Compared to my TP9, the S9 has better engraving, triggers are the same and the action is as smooth or maybe a touch better. The only difference is the rifling. Personally I prefer polygonal because it cleans up easier and should last longer, but I shoot both types and can tell no other difference in accuracy or recoil... the factors that really count. Enjoy your new Kahr.
Judging by today's left wing, looks like Senator Joe McCarthy was right after all.
