I've been using the Kaiser sight tool for removal and instalation of dove tail sights and while I think it worked pretty good, I broke the tool. I ordered picked up another Kaiser from a friend who didn't need it anymore, and it broke also in short order. Both tools broke in exactly the same place, the steel frame cracked straight across through one of the holes where the threaded rod goes thu. I'm going to have them both welded up but there's gotta be a better tool out there that can handle most sights. I need something that is pretty universal as i've been getting everything from Kahrs, Kimbers, Glocks.. Sig and the list goes on. Anyone have good experience with a particular model?
