Titanium might be a little much, I come from a sportbike background where every little bit of weight savings counts, including spending hundreds of dollars on titanium nuts bolts and screws but I'm going to stick with stainless steel for these for now as I can't see titanium offering any advantage at this point. I'm in Reno till sat night when I should get home in time to put all the new bits I got from cz custom into my sp01 in time to shoot a match on Sunday. I have new springs, a comp hammer and a single action only trigger waiting for me at home along with the huge oversized safety rocker and aluminum thin Grips with griptape I just installed. Can't wait for Sunday:)
