You are correct. Titanium would lack one important feature of steel. You could call it impact resistance. The titanium would beat itself into some unuseable shape in a short time. Maybe someone could work out a steel insert in the titanium, using investment casting. I read a report where someone was considering making a barrel out of titanium. They figured on the first shot the rifling would mashed flat. Due to a lack of impact resistance. You could make several parts out of titanium, but would it be enough to matter. A polymer frame looks more promising and doable, plus easier accomplish
