If you have the skills you might want to consider the BHSS SFS system which will give you an ambi safety and decocker function to the SA35.Thanks for the info, not the answer I wanted but it is the answer. Also thanks for the BHSS link. That may well be the one I put on the Israeli Kareen. I made it a lot harder than it needed to be by not checking function before putting on right side lever. The issue of not working was interference with grip rather than fit of safety. Will not make that mistake again. I guess I could always go with a CZ 75 decocker and trade double action first shot for cocked and locked with ambi safety.
