Does anyone have experience with Infinity titanium handguns? I have heard that titanium is soft and wears rather fast. Infinity titanium is supposed to be harder. I am considering the Tiki-T, it has my globes aching and I cannot get it out of my mind. I am not comfortable with the titanium though.

Titanium is much harder and stronger than steel. It is slightly brittle and can't be rifled as of yet. They require a steel insert for the bore and rifling. I wouldn't expect them to break/crack any faster than a steel frame. They do transfer more recoil back to the shooter due to the lower mass. Titanium is also very sturdy at high temperatures. The SR-71 Blackbird is constructed with a Titanium skin and supports. When it rockets at super sonic speeds, the hulls temperature can run about 900 degrees for hours on end. The Blackbird can do this day after day with very little damage to the metal.
