Seems like history has been re-written.
No, just a different author with a different mission.
As for using ball ammo, compare 9mm ball v. 9 mm JHPs.
The same applied to the 30 carbine. Soft point bullets, made to expand at MV of 1900 fps, have proven the M1 to be a fine defense weapon.
Inside of 50 yards, what you have is a combat accurate, fast shooting 357 mag.
Not a bad tool at all.
