If I ever get a Ruger SR1911 - one of the things that impressed me about the specs was the titanium firing pin. Recently I read a thread where an obviously experienced gunsmith did an extremely thorough review of the gun, checked all dimensions, did a range report and then replaced several parts or reworked them. One of the things he did I do not understand was replace the titanium with a steel firing pin. I figure titanium is a higher strength metal alloy - but maybe there is a good reason why steel is better than titanium? Or maybe the replacement was a particular brand or type of firng pin and that is the real difference. What is wrong with Ruger's titanium firing pin?
