And did you need any other part beside the hammer?

Hi all, I would like to install an xtreme hammer, xtreme firing pin and xtreme recoil guide rod on my large frame Stock II. But Eric Graufel's and tanfoglio website have got me a bit confused whether I need additional parts like interruptor, hammer strut, pins and a new sear and maybe other springs as well. Has anyone installed these parts before and would like to share what additional parts I would need? Thanks, uwe
