As the title states today I replaced the original sights on a Kahr K9. Wow what an ordeal. Online research warned me that I should "send it to Kahr to use their huge sight press on because their dovetails are way too tight." Had it not been for the assistance of a machinist friend and his amazing tool selection I'd have been up the creek. Super stoked and proud to have pulled it off. Hoping the new sights will improve my accuracy with this platform. I can't wait to try it out. Also can't believe how tight those suckers were and how much hand fitting was required to install the new ones.
