Hi CGN'ers. i recently picked up a Chiappa triple crown but the front sight was beat to crap and has to get replaced but I can't find any info on the thread pitch for them and don't want to buy one of each to find out! if anyone knows what it is that'd be sweet.
I can add that it is not a 2.6mm thread as that's the first one I bought.
