Edited to add:
Other than forgetting to mention the necessity of changing the recoil spring BEFORE it needs to be replaced, I also forgot to mention that in some of the earlier models, reportedly there were some problems with the K-9 in digesting reloaded ammunition. I don't know if it was because of a tight chamber, the poly rifiling, or, most likely, reloaded ammo that wasn't up to spec.
Mine has never 'bobbled' with factory ammunition. That said, its only fair to mention that the only factory ammo that has been fired in this gun in quantity has been mostly Cor-Bon 115 +P JHP and some Wal-Mart Ball.
I tried a box or two of the new Cor-Bon DPX all copper ammunition. No problems there either. If I ever win the lottery, I may buy some more DPX.
Leather Arsenal makes a dandy IWB holster for the Kahrs. For me, I can forget about re-holstering a drawn weapon worn IWB in a leather holster.
If you follow through with your intended purchase, I don't think you will be disappointed.
I liked my K-9 enough that I bought the tupperware frame version also. The steel frame gets more range time, the plastic frame gets more carry time. Both work with Cor-Bon 115 +P ammunition.
The Kahrs are not high in the 'tinker factor'. Other than tritium sights, or a change of grip panels, there isn't much that I am aware of that can be done to 'em that can make them any more dependable or 'user friendly'. That being the case, it may be a bit unlikely that a used Kahr would have been 'smithed on by Bubba' at the kitchen table using a rat-tail file and his trusty cross-peen hammer.
Other folks may have an entirely different opinion. Maybe I was just lucky, I dunno. As I said, I like mine.
