Looking at the 10mm. What advantages does it have over the standard .45 Auto?
Depends on what you mean by "advantage". 10mm has higher muzzle velocity and energy, greater recoil, and better penetration than a 45acp. It's a cartridge best suited for hunting mid to large size animals. For self-defense, IMHO, it's overkill and not necessary compared to the 45.Looking at the 10mm.
