The S&W scandium 1911's are an outstanding carry gun. I literally wore out an old LW Commander, which actually didn't take very long. The frame eventually cracked on the Colt from continued use of duty ammo. Scandium, alloyed with the aluminum, keeps the frame from work hardening and subsequently cracking. Makes the pistol stand up much better to continued use. I worked for Smith during the intro of the Scandium line and saw many thousands of rounds fired through test guns. Great product, great company.
