Saw on one of the "G" forums, the titanium safety plunger had a bad rap & from the comparison pics of the titanium and factory one after use, I agree. The factory didn't show much wear, the titanium showed signs of serious wear, almost chewed up.
Given that info, and pics, I'd be hesitant to go this route.
If your gun isn't broke, recommend seriously reconsidering this.
Either way, good luck
