What about titanium as a Luger frame material??

GT,
I was thinking of the weight factor and using the 7075-T6 for cannon forks and barrel exteriors for lower specific impulse applications. T-"x" is a heat treating specification. Where 0 = dead soft, and 6 = the hardest)
I hardly think that it would be worthwhile to machine a Luger frame from stock 7075 aluminum alloy, the machining characteristics are not that much superior to low carbon steels with sulfur added for fee machining. And the steel machines so much smoother.
The 1100 series carbon steels are probably the best, when balancing the ease of machining against the life expectancy of the Pistol.
I believe that the early types of steels developed by "Krupp" were the best Barrel steels of the day and for many years there were no better steel for rifling.
To my knowlege 1137 was the most frequently used barrel steel from the early 1900's to the 1960's, when sintered carbide and ceramic button drawing tools replaced the tool steel rifling cutters used by "Pope"and the other great barrel makers.
