I haven't gotten to look at any titanium parts per-se, I know that they are particularly fond of making compensators out of titanium because it increases their longevity many-fold (relative to aluminum). I believe that they used to offer slides in titanium as well, but now that the GunBuilder software is down for some reason, I can't say with certainty. I know there was a small list of external titanium components available (the magwell for example as well), and I stayed away from it because I didn't want to pay close to $10K for my pistol
