Bought an early stainless K9 and it's been my daily carry ever since.
People seem to want ultra-light polymer guns these days, but the K9 has a great deal to offer.
One is less recoil, another is a more solid feel in the hand.
The grip feels like a miniature Browning Hi-Power, and the trigger feels like a good S&W double action revolver trigger.
It has a very high "shootability".
People who run the small polymer autos at shooting schools are pretty worn out by the end of the day.
K9 shooters are still good to go.
Once you learn how to shoot double action you'll love it.
It's as safe to carry as a DA revolver, and my K9 has been a true 100% reliable since the day I bought it.
Unlike most other autos the K9 doesn't need anything in the way of alterations or "fluff & buff", and there are very few accessories around because it doesn't need any.
A pocket gun it isn't and it isn't inexpensive.
Kahr started the whole mini and micro gun thing and of them all, I still prefer my K9.
There's only one real quirk and that's that the magazines tend to shed rounds if carried loose. Pick a good mag pouch and that's not a problem.
