I'm planning on buying my first gun in the near future and need some advice. I have my choice narrowed down to the Kahr K-9, Sig-239 9mm, and HK P-30. The only gun of the three that they have a the local range is the Sig 239 with Houge grips. They also have some p-series Kahrs but no HKs. Whould shooting the P-series tell me anything about the K-9? What are your thoughts of buying a model that you've never shot?
