Im working on extending the grip on my c9. I had a c9 10 round mag cap that I had changed out for a c9 8 round mag cap. That way it works in my 995. So I have taken the old 10 round extension and hollowed it out so a 995 magazine will fit through it. Making a permanent grip extension. In doing so I lose the option of using the 8 round magazines but I have big hands and never really liked that magazine anyway.
