I have a model 59 9mm in blue that has had the rear sight (lollipop type) broken for years. No new parts are available and the used ones look horrible. I saw somewhere that a person used a 2.5mm screw from local hardware store, but it has the wrong thread pitch. It goes in a couple of threads and then binds. My 38 cents down the drain. The original mics out to 2.5mm. Does anyone know the correct thread pitch? Any other replacement screws or complete rear blade assemblys that would work? With a machine shop in the basement, I may just make a whole complete rear blade and screw from scratch, but I thought that I would try the easy way first.
Thanks in advance! Charles
