I have a K9, the original steel frame compact Kahr 9mm.. I have had it for over 10 years. during an idpa match a couple weeks ago the slide stop lever broke. i called Kahr, they asked the SN, and if I was the original owner, then sent me the part free of charge. The part they sent me is stainless, but I suppose thats my fault for not being specific.. this is still one of the most confortable to carry and shootable little carry guns around in my opinion..
