I bought these on the Kahr website. I think Hogue makes them to Kahr's specs and design. I bought the checkered grips about 2 years ago, and the smooth grips about 4-5 years ago. Wood color varies a lot, but I was very pleased with both of these. The checkering was really aggressive though and needs some wear to be comfortable. Prices are really good, too, compared to Hogue grips direct.
I bought a set of Hogue wood grips for my P245 and didn't really care for the color at all. Didn't look like their pic. I kept them though, thinking I would like them more as I got used to them. Wrong! Oh well. I've actually put the factory plastic back on.
