After tweeking my PM9's Meprolight rear sight the old fashioned way (with a hammer and punch - such high precision ;Q ) I ran across this: Glockmeister Sight Tool Does this come close to working with a Kahr? Is there anything like this that does? I'd rather spend the money for the correct tool than a replacement Tritium sight. Kind of reminds me of the old saying: "When all you have is a hammer the whole world looks like a nail". Don't know who said it but I always try to have a nice selection of hammers to choose from.
